oh cool
thanks again

oh.. our scores are very close
thanks for that
what do you plan to take?

do you know about BITS hyderabad
i want to know about my chances of getting ECE there

my BITSAT score is 325 .what are my chances?

well they shoot photons carrying enormous energy
thats the only way they can achieve something like that

what no one wants to even try??

no i wont contradict you
but the force in this case is no different from any other
it is the same as any other force but acts only for zero s
but there is definite impulse as there is a definite change in momentum but since time interval is zero the average force tends to infinity acting over a zero distance and you cannot calculate work by F x s
but the important fact is such collisions do not occur in reality
so one can always calculate work this way also

but this is out of JEE portions
as long as JEE IS CONSERNED kirchoff's law is very well applicable and what shikhar told goes.
the concept is confusing and my best suggestion is that you read about it after JEE (experience)

who told kirchoff's law is applicable in an AC circuit
almost all books use kirchoff's law in AC circuits
but trust me they are all wrong
kirchoff's law states
integral of E.ds = 0
Faradays law states integral of E.ds = d fi/ dt
even though the resulting equations are the same
its completely wrong to use kirchoff's law where there is a changing magnetic field, in such a case only faradays laws hold
if you want to know more tell me.

a billiard ball strikes an other elastically.

the other ball was initially at rest

now the work done by the first ball on the second ball is obviously its energy right?

this is the indirect way , i want you to try and find the work done by applying force x distance and tell your conclusions.

alright i know many of you here watch dragon ball zbut have you ever wondered why actually its not possible to simply convert energy within you in pure light energy and shoot it at some one?

if you have tell me, if you havent tell me by 24 hrs , by then i will tell my answer.

the best answer gets two hats.

when will CET solutions be out

hey yar i dont think that can be
see the mass distribution about AC and EF are different

you mean d-orbitals
