Physics: Post your doubts here!

[Peter Check]

ANYONE HAVE REVISION SHEET OF THE PRACTICALS???

 

[Cem]

Hey ya,

second attempt at AS Physics tomorrow.... :/

And I'm in Year 13. Do you guys know if I can still resit this AS Physics exam even when I'm not going to school anymore? because I'm pretty sure that I'm gonna mess it up tomorrow....

Physics is my life and I love it. Only problem is that my grades are not good at school because these CIE exams are so weird. They also sometimes ask stuff which is totally unneccessary to study Physics at Uni and they only do it to make CIE more sophisticated and only Top students who learn EVERYTHING possible are gonna get top marks ....

But yeah back to my question: Is it possible to resit it when you're not going to school anymore (ie between school and uni)?

How?

we got the stess 9.1 *10^8.so stress=force/area.u will get the area of the rod.then subtract the cross sectional area with the area of the rod

q.5 part b.... and q6. part b...

http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s06_qp_2.pdf
Q.5. part b... and Q.6 part a...

q5b
w= f * s
f = k * x

therefore w= kx^2 since s is same as x

to show the answer simply find area from 0 to x2 and 0 to x1 and subtract

6a can't really draw it for you :\

6b
distance between 2 nodes is 0.5λ and distance is 32.4cm so λ= 64.8cm

s=f * λ therefore 512 * 0.648 = 332

http://www.xtremepapers.com/papers/...el/Physics (9702)/9702_s03_ms_1 2 3 4 5 6.pdf

bcoz previously it states at the beginning of the qn that the lamp functions normally at 6V and from the graph at 6V current is 40 mA
hope that helps...please help with my qn too....tx
