[shrewd galleon]

Good Evening/Day, I would like to ask if anyone has any good material (research, thesis, dissertation) or anything that would contain the C3-type plant respiratory apparatus.

Yo when trying to draw the lewisstructure of IF_5 i cant seem to figure out the amount of bonds
Valence electrons: 42
Then 6.8 = 48 (for the octect rule)
48-42 = 6
6/2 = 3
So i get 3 bonds, but that is not correct, someone whom can help me?

[lyric dove]

sorry for the late reply my guy, but IF5 has an expanded octet: 5 bonds w/ one lone pair of e- (square pyramidal)

i don't think u can draw that one without violating the octet rule, as you can when drawing a structure like SO3

[quartz comet]

preciate you ma guy

Hello there! I found out today that I am getting into pharmacy school. My ultimate goal was to get into med school but it didn’t work out. I really like pharmacy though. What should I do? Should I go to pharmacy school or retake the exam next year to try and get into med school?

[lost thunder]

If you really like Pharmacy, look into options once you get out of school. A few of my friends who did pharmacy are doing research for a drug manufacturing company.

[cunning crescent]

if you are on pc it looks like this
if you are on mobile it should be similar i dont really remember

Does anyone have any good resources on how to determine how a compound will react at high pH levels?

[lyric dove]

any of the homies wanna explain why this reaction favors the products even though the products consist of two hydroxide ions?

i thought the reaction favors the side w/ the weaker acid and base? or does the rxn favor the right because oh- as an acid has negligible acidity?

[quartz comet]

the reaction favors the products (two hydroxide ions) because the oxide ion is a very strong base that reacts readily with water, and the resulting hydroxide ions are more thermodynamically stable. This drives the equilibrium towards the formation of OH −ions.

[untold spruce]

Why is tension in so many direction in string

[queen loom]

Tension is only in one direction, I think you must be reffering to the Tension's force components? TCosthta and TSintheta?

[untold spruce]

No

[queen loom]

I don't understand then, can you elaborate?

[untold spruce]

How to send photo ?

[queen loom]

You can add an attachment

The plus icon

[untold spruce]

Only poll option is there 😐

[queen loom]

That's weird

Maybe try another device?

[untold spruce]

Don't have rn

|--><-------><-----O -->mg
T T T T

The object is supposed to be hanging

[queen loom]

Wouldn't all T be equal? as same tension on entire string? unless the string is made of sections of different materials.
Also I feel like that is negitive tension, (idk if this is relevant to you you can still call that force "tension" but the arrows represent direction of compression instead)
Accurate arrows: |--<->-----<->-----O -->mg

[untold spruce]

Yeah all tension are the same

Also , it is supposed to be hanging

The direction are correct
But why are they reversing directions

[queen loom]

yeah then it is just one Tension you don't have to bother about all,
you can just solve it considering it as:
|------------>-----O -->mg
T

[untold spruce]

I see

[queen loom]

Well I mean all the science I have studied and learned, Tension is in that direction as it kinda "pulls" any part of the string
while compression compresses a string or a rod
an example would be if it was a rod that is vertical and the weight is on top of it, then the weight is compressing it and the compression would be shown as:
|-------><-----O-->mg (weight on top)

[untold spruce]

Thanks

[queen loom]

You should google or youtube direction of tension and compression force on string

it'll be clearer

[untold spruce]

Well I can't actually use Google or yt till 3am tho

Anyway thanks

[queen loom]

ah alright

[queen loom]

@untold spruce oh and btw the reason this is is because all those T that are represented are because the tension is applied to every single part of the string so you can represent it as many times as you want, but in the end it is just one force acting over the entire string, so while solving for forces it's just one T that matters

[untold spruce]

What do

[wanton sparrow]

Hey, is the answer b?

Sorry, 2)??

...

I'll explain it here

We know that horizontal components of velocity in projectile motion remain the same as there's no acceleration along that axis (g is perpendicular to it, so it's not considered)
Thus, taking x component,
V cos alpha= u cos theta
V=u cos theta/cos alpha
V=ucos theta sec alpha

@solemn cave

[solemn cave]

i dont hav the answer key but i think ur right 😭

thank you so much man

yes i did

i was doing hte same thing but then i

Is there a way we can identify the starting and ending of an intron sequence in hnRNA?
Do ping me while replying

[lost thunder]

Isn't there splice sites with 5' GU, 3'AG

There's also ML Algs that do this, that's what atleast what i did in my lab a few years ago

[lost thunder]

^

[midnight jolt]

Our instructor gave us a dna strand and asked us to make hnrna..we made...now he asked us to splice introns andmake mrna...manually pen and paper...so how is that GU and AG? I have no idea literally

[lost thunder]

Oh that's a different question

[midnight jolt]

Like how do I identify introns sequences in my strand?

[lost thunder]

I was using canonical splice sites

[midnight jolt]

Okay I have noidea what it is supposed to be

Can we dm?

[lost thunder]

I prefer not so now, cause I'm going back to work.

[sand cloak]

Anyone from india??
I have a paper tomorrow and want to study biotech principles chapter

[hot prairie]

pls help i need to find the vertical acceleration

[queen loom]

what is the direction of the vertical acc.? up?

[hot prairie]

i got to this point

[hot prairie]

down

[queen loom]

why's it in minus then

[queen loom]

no that's weong because you should also consider other forces not just the 5440 because it is opposite to it

[hot prairie]

i did consider the other forces

i considered the air resistance and gravity

i considered 3 vertical forces air res, gravity and the engine thrust

to find net force i just did engine thrust - air res - gravity

[queen loom]

wait yeah

you solved it vertical so I didn't understand sorry lol

but then

I think maybe the question wants g net?

as in find the Fg and then find g?

I don't understand what you mean by vertical accelaration, if it the accelaration put upwards to counter all downward forces then the signs will be reversed and your value would be correct

actually yeah

but you say it's downwards

so idk

[queen loom]

Do you think someone who is bad at chemistry (and hence dislikes it since a long time) can actually figure it out and get a good grip of the fundamentals and hence proceed to do research and deep studies in it?

Context: That someone is me and I have to really start working towards deep studies in it because of my major but I will have to clearup my fundaments first, but because of my past dislikes for it, my confidence is low as to if I will be able to do it or not

[lost thunder]

Anything is possible if you work at it.

[lost thunder]

Your confidence is related to your dislike which maybe because you probably didn't do too well in it. Tie your confidence into the idea that you'll aim to learn and acquire it. It's only the actions you can control that should be the most confident you are.

[queen loom]

Thanks lol I will try

[lost thunder]

Trust me, if you don't know something ask for help and be to explain why

Then practice it religiously

This applies to anything you want to learn and approach

[queen loom]

yeah

I will do it properly and throughly obviously I just wanted confirmation from somebody that it is doable cuz in my head it was impossible lol

Can anyone explain to me positive, neutral and negative control in experimental setups for biology?
(Ping me while replying)

[timid kindle]

right so the positive control: reagent that always gives the expected result from your hypothesis

negative control: gives the baseline for the experiment eg. water

neutral control

This is murky but its a lot like negative control (these are more found in group studies) where eg. one group acts as the neutral baseline

for instance in an IKI test for coiled polysaccharides

Starch from potatoes would be the positive control

Water the negative control

Glucose monomers/ simple sugars the neutral control

both of them are aromatic lol ph stands for phenyl

[shut hornet]

yea ik what Ph is lol (i meant im bad in remembering chem stuff anyways not logic)
in the second case the charge is fully delocalized in the aromatic ring of 6pi e- and also idk if u know the order but its AERHI which stands for aromatic electron then resonance so aromatization is given more priority
also the ring is going from a non-aromatic to aromatic ring so obv it would be more reactive compared to A which is just resonance stabilised

is there any onewho know where i can find the free components of tailwind css web?

[quaint remnant]

can someone pls explain how to solve this?

[clever rose]

The reaction is = 2A + B ↔ C + D
The Equili Constant is kc = 10^12

[A]0 = 2
[B]0 = 1
[C]0 = 0
[D}0 = 0

A is 2x because A has a coefficient of 2
C & D, both increase by x and 3x

so that makes it
[A) = 2 - 2x
[B] = 1 - x
[C] = 7 + x
[D} = 3 + x

So then the Equilibrium expression is Kc = [C][D]/[A]^2[B]
and then B = 1

I think that's right (its prob completely wrong)

[open cargo]

i just wanted to know why the sign for friction in eq (i) is in negative?

[shut hornet]

becuase the friction acts to appose the motion cause by F

[open cargo]

so in that case won't friction generate angular velocity like clockwise which will support the force

[shut hornet]

ok so when F is applied point of contact tends to slide forward so friction acts backwards
and we have to maintain v=rw so friction causes rotation to increase rw

this is basically how brakes in cars work

if you cant understand , friction acts to avoid slipping which is true when v_com=rw to oppose rw friction acts in the opposite direction so that v=rw

[tulip bridge]

Alakh sir?

[open cargo]

thanks

[open cargo]

ofc I ain't getting fooled again by a coaching already made a very pricey mistake in hs but not again😭

[tulip bridge]

OMG TWIN 😭

[open cargo]

dude istg they didn't even lemme take a scholarship test and told me that they will give 75% scholarship because I scored 96% in 10th boards and guess what was the price after the said scholarship

[tulip bridge]

How much,2L?

Like whole fee I'm saying without deduction

[open cargo]

first they said 3.2 is the best price and made it look like they reduced a lot as we insisted by making it to a 2.7

you get me?

like outrageous

[tulip bridge]

WTH

I say why don't they just ask us for our organs instead

Even that wouldn't be enough

[open cargo]

fr

[tulip bridge]

3.2 is like .. shit (ACTUALLY I PAID THIS MUCH) still drop

[open cargo]

and the worst of all I didn't even go in 11th cuz I got sick due to yk both schooling and coaching

[open cargo]

the mufuking coaching tshirt even gave me a dermatitis a fucking allergic reaction my whole skin grew small bumps💀

i feel like this convo should happen in #venting lmao

[solemn cave]

how do i do the naming

[normal girder]

Start with f. grp side to left side

[thorny gyro]

3-chloro-2,4-dimethylhexane

[normal girder]

4-Chloro-5-Methly-Octane

Wait what

[solemn cave]

Wait what

konsa

wala

[thorny gyro]

what question are we doing

[normal girder]

How di??

[solemn cave]

yeah what

4?

[normal girder]

Mine is correct

[thorny gyro]

isnt chloro 3

idk i dont have chem lol

[solemn cave]

I don't know where to start from, left or right

[normal girder]

Nopen4

[thorny gyro]

but chloro should be 3

[thorny gyro]

right ig cuz its closer?

[solemn cave]

it's the same

[normal girder]

Do you know the priority rule?

[solemn cave]

toh we will go alphabeticallt

[normal girder]

NOOO

[thorny gyro]

woot check answer or ask your teacher

[solemn cave]

OH WAIT

[normal girder]

Which is close to f. Grp

[thorny gyro]

i stared from bottom

[normal girder]

Start from there

[solemn cave]

What the fuck is f group

[normal girder]

Functional groups

[thorny gyro]

so 3 chloro 2,4 di methyl hexane

[solemn cave]

OH

[normal girder]

😭😭BRO

[solemn cave]

OHHHHH

no listen to me

[thorny gyro]

WOOT CHECK THE ANSWER

[solemn cave]

im asking abt th 4th one

[thorny gyro]

WHICH ONE IS CORRECT

[solemn cave]

I don't have it

[normal girder]

Do you study chemistry?

[thorny gyro]

yeah 4th is 3 chloro thinfy

[thorny gyro]

nope lmao, im a cs student

[solemn cave]

yeah this is right

thanks miki

you're right

smartass

[normal girder]

WOAHAH

[solemn cave]

The other two I also wan

There is no chlorine in third

[thorny gyro]

nvm what the fuck am i doing

idk chem

jm just guessing

dont rely on me woot

😭😭🤣

[normal girder]

3,4-diMethly- Hexane

[solemn cave]

kh

[normal girder]

Yes

[solemn cave]

oh

[solemn cave]

ye kese ho gya

[thorny gyro]

cuz 2 has bromine, 1 has chlorine 😅

[solemn cave]

But

[normal girder]

Start numbering from no. of f.grp if it's tie

[solemn cave]

chlorine bhi toh 2 ho skta

Oh

[thorny gyro]

1 has iodine as well

[normal girder]

And write iupac alphabetetlicy

[thorny gyro]

too many fucking rules

i hate chem

[normal girder]

Alphabetically

[solemn cave]

OKE

[thorny gyro]

especially organic

[solemn cave]

oih

[thorny gyro]

i have to do it next sem

im gonna learn from yt

[normal girder]

Gotta learn it anyway

[solemn cave]

then bromo 1 hona chaiy

😂😂😂

[normal girder]

LLN? pata h?

[solemn cave]

yeah it's true

What is this

[normal girder]

Lowest locant rule*

[solemn cave]

Yes I do

[normal girder]

Vo use karlo

[solemn cave]

oh

[normal girder]

If we started from bromo

It would be 1,2,2

[solemn cave]

han

[normal girder]

If from other side

It would be 1,1,2

[solemn cave]

Wait

OH

OKAY

[normal girder]

We want the lowest number

[plain knoll]

hey everyone i need some help with an assignment i have in my computer architecture course. Assignment requirements are:

To build a Direct Mapped Cache with 4 bit memory address and 2 bit data address without any replacement policy, we need:

1. Decoder with enable and decoder without enable
2. Multiplexer with enable and multiplexer without enable
3. Single bit memory elements
4. XOR gates, NOR gates, AND gates
5. Bit switches to give inputs
6. Display units to check the outputs.
7. Wires to connect.

and the 'starting point' is the below image (which ive already built)
edit: can't post it, but would appreciate some general guidelines on how to link all of this together. Also taking stimulator recommendations.

[compact plover]

Uh

[plain knoll]

same

[manic herald]

anyone know the mechanism for this?

[dark cliff]

Guyz is there any way to learn chemistry or roadmap to start with it bcz I found it difficult to learn chemical reactions?!?

Guys can someone please help me with a Chem ques?

[lyric dove]

ask the question

[thorny gyro]

I am unable to upload files in this channel 😦

Can I DM you?

[thorny gyro]

Hello guys
Is anyone here from India preparing for medical entrance exam?

[clever rose]

anyone know any good self study material for neuroscience?

[thorny gyro]

Meee!

[thorny gyro]

Can we talk pls

Ofc!

Dm?

[thorny gyro]

Hey are you okay if we talk ?

Yees!

[tawny jewel]

depends on what specifically in neuro/how you learn. what topics?

im a phd student in neuroscience, i think i can point u in the right direction

[blissful parcel]

wow did not expect computer arch here

[plain knoll]

figured it out btw

but yeah its kicking my ass a bit cuz my teacher sucks

[blissful parcel]

oh cool, which uni are you from?

[plain knoll]

balkans

shitty as public uni

[blissful parcel]

ooh, I would recommend you to watch onur mutlus lecs

they are good

[plain knoll]

thank u for the rec, will check it out

[blissful parcel]

yes and please post comparch questions here ( I would love to try to solve them)

[plain knoll]

oh ive seen some lectures from him

[blissful parcel]

He is a really good prof too

[plain knoll]

next assignment is building a single instruction cpu

[blissful parcel]

verilog?

single cycle

?

[plain knoll]

nope one of those drag and drop stimulators

[blissful parcel]

ahh, I only know verilog and ASM

[plain knoll]

ill give u the full requirement when i start workin on it again

[blissful parcel]

yes, my intended field is comparch as well

[clever rose]

Just any good starting point would be nice if that makes sense

[tawny jewel]

the textbook Foundations of Cellular Neurophysiology by Johnston and Wu has practice problem sets for a more math/physiology focus

https://compneuro.neuromatch.io/tutorials/intro.html

neuromatch academy has full courses walking you through a lot of the basics of compneuro, applying research papers into programming

really just depends on what specifically ur studying

[clever rose]

alright i see anything on Neurophysics if thats even a real thing

also if you don't mind how is your experience in Neuroscience, i think that's what I'm going to major for my ba and than do grad school and sorts

[plain knoll]

this is the site our prof took the assignment from:
https://cse.iitkgp.ac.in/~chitta/coldvl/comp.html

I also found this, and it seems relevant:
http://simplecpudesign.com/simple_cpu_v1/index.html

[blissful parcel]

I see

[tawny jewel]

neurophysics isn’t a super real field, give me some specific interests

check out christof koch’s work his stuff might be up your alley. Also a must is the allen institute. they have open datasets and some really ambitious projects in that realm that might interest you

[tawny jewel]

are you still in hs? that’s great you’re getting into it so early. i was interested in neuroscience at your age and now im pursuing my phd and planning on staying in academia afterwards. i have no regrets

an area of study that you’d might be interested in with neurophysics is the open study of consciousness; it’s a burgeoning area of interest that’s popular right now in neuroscience

both the allen institute and christof koch’s work are heavily focused on it

david mccormick at university of oregon is also studying it

feel free to PM me and i can send paper/lecture links and some good book reviews

and of course, you should start learning programmming now!!!!! if i had one piece of advice, download a text editor and start coding ANYTHING, you will be a god at my age if you become best friends with Python, or even MATLAB

[plain knoll]

I dont know if ur still intertested, but i basically have to build this:

Can anyone help me sovle this question?

[copper python]

Idk

Lemme know if ma solution is correct or not

[thorny gyro]

it should be none of these as the reflected ray is making zero degree angle with the horizontal

[rain abyss]

for those who do engineering, is this a suitable way for splitting the wall into regular shapes cause I dont see how else I can solve this

[tranquil holly]

The answer is B. 2θ, mate.

[thorny gyro]

🥲 sorry then

[tranquil holly]

I apologize mate, that was a typo, sorry sorry. The answer is correct, The Ray of reflection is parallel to the horizontal, sorry sorry.

The answer would be D., then.

[tranquil holly]

Yes, this is correct.

[polar vale]

oopsies

@tranquil holly any equatons involved?

[thorny gyro]

https://tenor.com/view/iu-cute-pretty-hae-soo-moon-lovers-gif-23052153

[tranquil holly]

It was just some common sense. 😔

I got option D. First too, but I didn't have the answer key and Google said the answer was option B. so I thought I might be mistaken.

[thorny gyro]

btw, you study in which grade?

[tranquil holly]

I am 16, grade 12.

[thorny gyro]

ohh

[tranquil holly]

You?

[thorny gyro]

ididn't know how i solved this question but,i just did it...
im in 10th

[tranquil holly]

Where are you from?

[thorny gyro]

India

[tranquil holly]

Yeah, this question was a mere common sense one, I was just complicating it with useless equations.

[thorny gyro]

yeah..

[tranquil holly]

Good luck with your Boards, man.

[thorny gyro]

thanks bro

same to you

[tranquil holly]

You must be having it in your syllabus, right?

[thorny gyro]

yup light chapter

[tranquil holly]

I just transitioned to 12th, so I'll be giving my exams in 2026.

[thorny gyro]

10th and 12th is quit similar

[thorny gyro]

ahhh got it

[tranquil holly]

Yeah, our syllabus only started a week ago, we started off with Ray optics.

[thorny gyro]

ohh niocee

[tranquil holly]

Anyways, just work hard.
Keep your concepts strong, that'll help you a lot in 11th. Don't be memorizing solutions unless you know it is 100% to come in the exam. Solve PYQs on a daily basis.
Everyone in the server will be rooting for your success.

[thorny gyro]

Thank you for the advice! I really appreciate it. I'll make sure to focus on understanding the concepts and practice regularly with PYQs. It’s motivating to know that everyone is supporting me. I'll give my best effort!"

guys please help (This is from CBSE sample paper 2025)

which is anode which is cathode, and how did you conclude that

theres a trick

its called LOAN

only for galvanic cell

LEFT OXIDATION ANDOE NEGATIVE

@mystic rose for any other help related to 12th , DM me !! always happy to help !!

[mystic rose]

I meant we have to identify from figure which is anode

[willow parcel]

in elecrtolytic cell oxidation happens on anode but there it is taken as positive

[mystic rose]

with respect to electrolyte right?

[willow parcel]

in the diagram we see current going from left to right , so electrons flow from right to left indicating that right side is our anode , Y--->Y+2

[mystic rose]

Ohh okay... I got it now

55 proton means, 55 electron, unipositive means 54 electrons. Now if you were to fill the orbitals using aufbau principle
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p
this is the config, and until 5p there are 5 s orbitals = 8 electron.

[solemn cave]

ohh so thats what unipositive means

aight got it thanks :)

[vivid lantern]

sorry wrong answer it should be 10 s electrons!! 5 s orbits = 10 electrons since 2 electrons per shell

[solemn cave]

yeah i got it dw

[copper python]

Yo guys can i get some tips on salt analysis (class 11th) practicals are eating my brains out

[spark crown]

Hi I have a project at school in physics or math about " cycles and loops ", any ideas ?

[rough bramble]

Learn it

Drink it

very interesting

math, physics but philosophy as well!

hi guys can anyone help me as i have my finals in a week i can barely study a year back i used to top in everysubject poeple were not even close to me my lowest was their their best. I dont know what happened now i dont feel like working hard or do anything i am not addicted to porn and jerking . Pls help me i am fed of my life right now i request pls soemone help me

[rough bramble]

First of all break that ego, that people were not even close to you, "people best was my lowest", destroy your ego. Well if you do it you will automatically feel amazed and not caring about anything, "ਹੁਕਮੈ ਅੰਦਰਿ ਸਭੁ ਕੋ ਬਾਹਰਿ ਹੁਕਮ ਨ ਕੋਇ ॥ ਨਾਨਕ ਹੁਕਮੈ ਜੇ ਬੁਝੈ ਤ ਹਉਮੈ ਕਹੈ ਨ ਕੋਇ ॥੨॥" ~Guru Granth Sahib ji -> Everyone is subject to His Command; no one is beyond His Command. O Nanak, one who understands His Command, does not speak in ego <- ima say it if you understood the line you might have chance to go out of trap .second of all i know you are feeling like shit, Well that happened with me tbh, i used to scroll through all the study methods or tips or tricks, it did work but not as much i needed, so i watched jamescholz mindset video and it made me go into consistency.

• you have a plus point as u aint addicted to porn

Start by 5 hours study (that usally works for me ) go 3 days with it then change to 6 or 7 hours then do it till 5 days and then go for 9 hours and then 10

(I am following it and i am on 8 hours per day)

By the way try 25/5 pomodoro to just start and then increase it gradually

Lmk if any help needed

[minor otter]

i am addicted too with porn some says its natural some says anything else dont know what to d o]

[rough bramble]

I hope you saw the whole message it was a bit long but still. Watching porn is not a natural thing? Watching it makes your dopamine go so high, which makes you feel depressed, so dont do it.

I would suggest stay focused app, its premium version is best!

It helps you reduce the way or just stop the way to reach that sin

[minor otter]

btw cann u tellthe title of james video u saw

and yes i read it all

[rough bramble]

On his channel

First video

thanks ! APPRECIATE IT

[minor otter]

and i suffer from porn addiction what to do about it

[rough bramble]

It cant be defeated, but can be controlled

[minor otter]

Tiips pls

[rough bramble]

Well looks like you havent read anything i said earlier..

[solemn cave]

can vectors be added algebraically

wait no

vectors cannot be added algebraically

but this isnt always true bcoz if two vectors have angle between them as 0 which means they r in the same direction they can be added algebraically

[solemn cave]

but a teacher said that this is always true

im confusion

[bleak oyster]

yeah in general but there are special cases where you can add them algebrically just as ya mentioned, if angle is zero you will treat them as regular number and add algebrically and if angle is 180, you can subratct them as, you get the idea

lmk if you still have some doubt about it

[solemn cave]

yeah so is the answer that it's always false or its isn't always true

[bleak oyster]

isn't always true, special cases exists

[solemn cave]

yesssssss

oke thanks

[minor otter]

i have read every word u said

but like in general u said to divine urself to the almighty any god u love but its easier said then done there are always urges that keeps holding u back i dont know how to block them

[rough bramble]

Yea thats true, read bible, Quran, Guru granth sahib ji bannis, bhagwat gita or any god you love. Read it everyday, dont try to read whole thing in 1 day, divide it have, consistency. So urges come but if you keep urself busy it is neglegible.

Find points from where you get triggered, and yes if you dont know you have to find it when u get an urge, write it. Everytime you have urge, try to eliminate that distraction

Btw man if you want to improve ur studies u should keep that shitty valorant game aside

I saw u were playing it

[minor otter]

Right man but how did u know i was playing

Tips to leave video game
As for an instance i can stop porn as i did avoid for a month whole no urges but video games nahhh i always fail max i went was 3 days

[minor otter]

Btw like video games affect ur studying as i have no knowledge on this

[minor otter]

@rough bramble

[autumn turtle]

you prolly study and play video games on the same computer in the same place

so when you try to study you're still habituated to playing video games in that place

so study in a different place or maybe not use your laptop ?

[minor otter]

Thanks

[lyric dove]

would path B be favored bc of sterics?

[vivid lantern]

Path b I would guess, since path a has phenyl?

What is the source of this question? @lyric dove

[bleak oyster]

yup path b coz of less steric

[lyric dove]

lab report concerning diasteroselectivity

[vivid lantern]

So is path b correct?

[lyric dove]

idk yet but i assume so

i just don't know if the carbonyl's pi bonds occlude the attack

[vivid lantern]

Pi electrons, electron density but it doesn't mean the obvious ph won't give any effect?

[placid brook]

pls help

someone

[rough bramble]

Alright easy peazy, just leave the question

[rough bramble]

See upper first triangle and 2 quadrilateral are wheatstone bridge so all centre lines will be cut. Try now

[storm crown]

please someone help me w this question

helpp😭

[thorny gyro]

is it 8?

[storm crown]

how did u solved?

[woeful talon]

i dont understand when do we equate forces compoments perpendicularly(Ncos30=200) and when do we equate in an angle(N=200cos30)

[rough bramble]

Use cell formulla of cell combination in parllel

Its Vnet = (e1r2 + e2r1/ r1+r2) +Inet(r1r2/r1+r2)

Try leme know ( i am not that sure let me pls ) !

[queen loom]

It's not about equating, you should understand how components of forces are calculated

[queen loom]

You should watch a youtube animation about vector forces and their components if you don't understand it by this, the animation will make it clear

[storm crown]

how will i get Inet?

the part after + is not needed

we found value of v from e1r2+e2r1/r1+r2 only

thankuuu so muchhh

u helped alotttt

[placid brook]

its not about that

well nvm

i solved

[thorny gyro]

can anyone explain wtf we're supposed to do for 9.20

all the solutions im finding online have formulas that aren't in ncert

[forest hollow]

9.10 1/feq = 1/f1 + 1/f2 (you can find it on pg 238)

[past axle]

Oh wait

Ahhh

[thorny gyro]

yeah but they have distance between them

[forest hollow]

in 9.10 they are in contact

[past axle]

I think you will have to solve it manually

[forest hollow]

and they're also saying to ignore the thickness of the lenses

[thorny gyro]

theres a formula 1/f=1/f1+1/f2-d/f1f2 but its nowhere in ncert

[past axle]

Like just how the derivation goes

[thorny gyro]

the manual solution isnt making sense

[past axle]

Wait let me try first

[thorny gyro]

yeah but even then answer doesnt match

[forest hollow]

it does though

60cm focal length and its diverging in nature?

the nature of the focal length of the concave lens is negative and that of the convex lens is positive

so you end up subtracting 1/30 - 1/20

that way you'll get -1/60 or -60cm

[thorny gyro]

nah 60s nowhere in the solution

[past axle]

But thats in 8.10

9.10*

In 9.20 there is an 8cm gap
