I've made a website to help students like me to access past papers faster. Check out signature below and share with friends.

P.S. I made it for myself earlier this year and got amazing reviews from friends and so I made it publicly available.

question 1 (d) does is it make sense if I rite

No

As seen by the gradient of slope ,as x increases at first T^2 increases but then it decreases

Question 4 (c) is it okay if I rite

No, because a difference of 4 is seen

Question 5 (a)

Its just like this (with a metre rule added)

I think you got the answer

A mistake:
q will have lower tension I think..

it would be:

p= 60N
q= 30N

Moment = l x force.
you can get more notes on moments at www.xtremenotes.wordpress.com

If length is more, the force would be less

Is Mark Scheme wrong for physics may/june 2012, second variant paper 1, question number 18. I think the correct answer is B. But in mark scheme, it is A.
Which one is correct? Please help. If that question is asked next time, it will be confused for the students. Thanks.

End Q of the wood will be hottest because the heat is not conducted away from the source by the wood.

This can be demonstrated by using the apparatus shown in the diagram. If a piece of
paper is fixed tightly around the wood / copper joint, the paper will singe on the wood side (high temperature)
but not on the copper side (lower temperature).

this forum is more heated than what i had imagined.
