Yusuf bhaiya🙏🏻

Where are u guys having confusion with that answer?

jee copies some questions from clayden directly

@hansika do clayden problems for a challenge

All the best to my dudes who have jee tomorrow!

@JohnRennie yes sir, noted.

Presence of god hence confirmed

god

but who built the walls there?

that means the universe has rigid immovable walls

we say that the universe is an isolated system

An isolated system has rigid immovable walls

All the best to everyone who have JEE Advanced tomorrow!

Thanks!

@EVO Ahh I did suspect this

Then i guess that's what the paper setter might be asking and if we solve it in ground frame we won't get N as integer and the paper instructions say that N should be an integer

@satan29 ikr like all inpho lvl questions

@LalitTolani Yeah but some people might want to attempt in the last month before jee

@JohnRennie Does this mean that the pressure right next to the train is what we get when we use Bernoulli equation in the train's frame?

Jk

@satan29 They won't ask similar questions in consecutive years xD

Let's hoard some rep xD

Oh ok then

Maybe I'll ask it in the main site after adv

Yes sir ans is 9

Yes sir, this is the problem :(

Yes sir

Because they also said assume laminar and steady flow

Yes sir, I did the same thing

Yes sir

Sir, I solved this one in the train's frame but if I try it in ground frame then I am getting wrong answer

spoiler alert for anyone who hasn't attempted jee 2020 paper yet

@JohnRennie Hello sir :-)

@Buraian Sweet! Thanks

Thank you sir :-)

Ahh I think I can do it now

Yes sir

Yes sir

Yes sir

Sir, how do i get started with this one?

@JohnRennie Hello sir :)

@RaMathuzen Is that a "yea thanks I understood" yeah or a "bad worded question and i am not really satisfied" yeah? xD

@RaMathuzen I reckon that first they sealed the tube and then put it in water coz note that l=110mm but water actually rises to a height of 10.3m. So if what u say is correct then the water would just come out of the upper open end of the tube in the first case

@RaMathuzen what do u mean by "we can only use P_o*(l-h)"?

@Lllt ah yes u will get plenty of time to clear backlogs after ur syllabus is finished. Even I didn't attend a coaching in 11th so had a lot of backlog but now it's all good. But I'll have to give half of the credit to corona for delaying jee

@Lllt cool, hope u r going good

@Lllt Thanks bro! I think u told me but are u 2021 too?

Ah alright sir. I think I can do the actual question now
