threshold for physis p42

[samy]

i noe =/ chalo lets hope for de best.gd luck for p5

hmmm yea same to ya

CAn anyone tell me about the calculation involving moles of gas in two containers, connected with a tube?
Did you just calculate the moles individually and then add them up...?
OR was there some other logic...?

almost all of my friends did the same.but i added up the volume and temperature..i too need help in it!
can anyone tell me the answer??

Well, i'll be asking my teacher about it.

We have to add the moles of both containers

 

[nisurju]

ugghh..bad luck!anyway,thanks for ur help

 

[Xam]

mine was 300 something
i forgot to change Cm3 to m3...

 

[nisurju]

which qsn are u talkin abt?3??

 

[Xam]

moles ques 2

 

[boy2011]

i forgot to change cm^3 to m^3.other wrkng was perfect so how many marks will i loose???????plsssss tell me..i thnk il lose 1 mark??as answer will be wrong other working was ok..?

 

[skyfox]

what is a mole btw ? im not sure with my ans..

 

[Xam]

@skyfox

n = PV / RT

 

[saadkhan]

there was a question about faraday's law of EM induction, and in the last part, they switched the voltmeter with a current supply, and we were asked to draw a graph... what kind of graph did you draw? damping one or the resonance one...?

PS. @ nisurju My teacher tells me that there wasn't any complication with the question, and all you had to do was to find out the moles individually using the formula ' PV=nRT ' and then add up the number of moles. :Yahoo!:

 

[WellWIshER]

i am actually surprised cuz their was not even a single challenging question!!!

 

[nisurju]

ok.thanks saadkhan.actually i had done a qsn of 2002 may june where there was a similar question n i messed up with it.the questions were not at all challenging.but dear,it sometimes depends upon the luck too!u cant do well in exam sometimes if ur stressed n so..but....let's see what happens.leave it to the god!

 

[nisurju]

btw,what do u think gt will b?

[samy]

ahhhhhhhhhhhhhhh...luks lyk i also messed up with the capacitor ques...
man i always did capacitors so well n in papers i messed up

 

[saadkhan]

i am actually surprised cuz their was not even a single challenging question!!!

how did you cope with the weird question about Op-Amps...?

@ Samy, how did you mess up with it...?

 

[saadkhan]

btw,what do u think gt will b?

Got to be 75, in my opinion, was pretty much easy, compared to past papers that i had attempted while practicing... IMO, the only difficult question was about Op-Amps...

i dont think i found the correct charge...and waxnt able explain well that why capacitors dont store charge...anddddddd also i think messed up finding C thru graph making it a mocro farad..goshh!!!
