11Which Variant?
Thanks a lot brotherx=lambda*D/a
(Lambda/2*D)/2a
x=1/4*Lambda*D/a
so answer should be.. 0.75. A
33
Two Equations
1) R = pL/A
2) Strain = F/A
If strain increases area decreases... according to 2.
Then according to 1 .. If A decreases R increases. So answer is D.
34 ..
draw a line from origin to each of the points... whichever has the lease gradient will give you the answer.. since gradient of the graph is I/V .. and resistance is V/I.. so we need the least gradient. as resistance is 1/gradient so Answer is C
Thanks a lot brother
For no. 33, isnt it strain = extension/original length?

The collision is inelastic so the speed of the ball after rebounding will be less than v but greater than 0. the answer cant be A or B because the change has to be greater than 2mv since it changes direction. d also cant be because it would make the collision elastic thus c as rebound speed is 0.5v which is in possible rangeA particle of mass 2m and velocity v strikes a wall.
The particle rebounds along the same path after colliding with the wall. The collision is inelastic.
What is a possible change in the momentum of the ball during the collision?
A mv B 2mv C 3mv D 4mv
answer is C.. plz someone explain
this one too?

question 36 ... syed1995 h4rriet . Thanks in advance guys!
You have to understand projectile motion to understand 14. The vertical component of the velocity at the highest point during a parabolic trajectory will be 0, and its horizontal component will stay the same throughout.Ty, I still don't understand 14, 19
Got it.. thanksAh my bad.. you'd use
E=Stress/Strain
Strain*E=F/A
If strain increases then Area decreases.
