Physics: Post your doubts here!

What was the answer for the diffraction grating double slit question where they asked which had greater separation between fringes and which was sharper?

Guys, I'm expecting at least 44 in Paper 21, 33-35 in Paper 11 and 25-27 in Paper 31. What grade will I get with these marks?

well you cant exactly say but i think it would be an A or a B
but more chances of an A

 

[Wolfgangs]

For the practical paper, how many marks do I lose in the table question if I have a wrong trend only, but everything else is correct. And, do I lose marks for the graph due to wrong trend? What about the gradient and y-intercept I found out using the graph with wrong readings?

r u serious man? -_-

u r right if the cake is more bitter thn bittergourd then uni n all tht would be other parts of the cake
==> the cake= our life

aww im genius!! *_*

i wont come for socialising to be precise.i came for papers only n my thread.i suck at physics.im like "taare zameen par" my frnds says with physics these days.whn the topper topples -_-'

aacha???? pg 510 pe q-4 zara solve karo

Ek aur doubt hai: From the formula in electrostats F=(1/4pi E0 K)(q1q2/r^2) me metal ka dielectric constant(K) infinite hota hai to fir electron circuit me kyu move kar te hai???????????????????

Jab ke us ke upar force zero hota hai

Hey guys, can help me with 2(b) (iii) R to P that column, work done on gas? Why?

 

[Thought blocker]

internal energy = (heat supplied) + workdone
for P-Q u find wd in part1
so just add
for Q-R workdone = 0 so U= 720
for R-P
u know sum of all IE are 0
now calc third IE
put in formula IE = q + WD
and get the wd

Use David Sang course book. Wait for someone else reply.

Guys for the practicals in Q1, there is a table drawing and taking the readings and adding it to it. Well, what if the table is correct, units and significant figures, but only the trend of readings is wrong. How much will I lose from that table question. Will they then subtract marks from my graph and gradient, even though they are correct with my results>?
