for 22 apply the formula of Young modulus
FL/AX=E
SO WE Need to find the change in length
f=20,a=pie*(5*10^-4/2)^2
e=2*10^11
u will get 5*10^-4
and for percentage multiply by 100
25) formula for diffraction grating ----> nλ = dsinΘ
check this out ---->http://www.s-cool.co.uk/a-level/physics/diffraction/revise-it/diffraction-from-a-diffraction-grating
so d = 1/N, N = no of lines
So, the formula = nλ = sinΘ/N
gradient = sinΘ/λ
So, rearranging the abv formula, sinΘ/λ = Nn
Ans = C
Hope i helped.

yeah i thought that too but the answers A :/
Any one understand the diagram for November 2010 paper 51? How do you draw it? It says coil Y is winded up tightly around coil X? How's that possible and mark scheme says there should be two independent coil labelled X and Y? Please help
its a simple transformer :/
the pic I have uploaded shows the 2wires winded..
plus the bold wire shows wire y, and the other one is x..
if u gt ths diagram abt how they will wind up.lemme know, othrwse I will make the whole diagram..
can you guys help me to draw a
diagram for Specimen paper 5 q
no 1.

please post the diagram.
please post which paper you are asking..
9) when the mass is at the lowest point, its kinetic energy = 0.
hence its velocity is also = 0 m/s
that means, either B or D.
since the first part of the graph shows the "UPWARD" velocity of the mass, hence the ans is D
Hope u gt it!

Hello everyoneI am new to this part of Xtremepapers cuz i hv just finished my O levels n in these vacations i wanna study for A levels .Although i created a thread but there was no reply. Actually i need the name of the best books for Physics A levels that most renown skools follow.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
