i guess u r talking about the bi) part right???
yes

Then I advise u NOT to look at the mark scheme. First.
Secondly there are different methods of doing the same questions. U try it urself first. if u have a doubt ask someone. And then if u still have a doubt look at the mark scheme. They only give u direct answers. They dont write each and every step.
Thats what my teachers advise me to do.

why this xtremepapers not opening papers link ???
Mene paper download karne hain or inn loogoon se site hi band kar diSome Error I guess. Its the same for everyone. Khudi theek ho jaye ga.

Q-5 Where they are asked to find out how long does each pulse rate last... See the graph in the form of a wave pattern. The line is constant between the two waves. So dont take that into account. For the first wave, see how long was the wave at its peak. It is 2 blocks. They have told that 1 block is 1 micrometer second. So 2 blocks will be 2x1 = 2 Micrometer second.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s05_qp_1.pdf
Can someone explain me q 5,7,11 and 13 of this paper

Q-13. Upward force = Down ward force.
w1 d1 = w2 d2.
upward force =5 x 2 ( 2 because the whole length is 4. see the rest of the length written as 2m.) (from 5N till 10N)( So 4-2 = 2m )
downward force = 20 x 3 = 60
Look at the clockwise moment now. The one perpendicular to the vertical length 2m.
again w1 d1 10 x 2 = 20
Equate all the three.
5 x 2 = 20 x 3 = 10 x 2
Resultant = (subtract the three) 60 - 20 - 10 = 30

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.
