guys i hate being paranoid but for 42, the graph for emf. It was a digital shaped graph with both in the same direction but the second voltage was greater right? because gradient was in same direction.

yh it was 7.2
-12, it was inverting

Guys i messed up in finding the gain...i got confused and used the formula for the inverting op-amp so will i get ecf

GUYS, ANYONE REMEMBER THE SHM QUESTION. VARIENT 42. DID IT SAY STATE AND EXPLAIN HOW THE TROLLEY IS DAMPED ??? OR DID IT SAY '' STATE '' ONLY.. I WROTE ' LIGHTLY DAMPED ' ONLY.

The gradient was in the same direction but one line was passing through positive values of B and other through -ve.
So wont they be in opposite directions? Does sign of B make any difference?

http://physics-ref.blogspot.com/2014/11/physics-9702-doubts-help-page-5.html read the explanation for Q34ii. it says"that since the gradient is in opposite directions emf would be in opposite direction to but in paper the gradient was in same direction

ik thaz wut made me draw the peaks in opposite directions
m still not sure y they were post to be in the same directions but many of my friends said that it was the gradient which had to be considered
because both gradiants are negative. So in the same direction the second line was steeper so the peek is larger.

Idk but over there values of B are GREATER THAN Zero only. There arent any -ve values as were in our paper

ok m a lil worried now
wut was the definition of bandwidth? i wrote 'the maximum signal frequency carried by a carrier wave x 2' is that right?
and like i dint mention the 'no increase in kinetic energy 'during melting...i just wrote abt increase in potential energy of particles
do u think there will be a mark for Ek as well?
