Shouldnt that be in whole numbers? 2*3 +1=78
3.5 in top half 3.5 in bottom half = 7 + 1 central = 8

Oh that was D I chose the option with the force of table on book, whatever option that was There is some exam paper of before 2013 with that same question I remember it now as I got it in my school exam paper 2 times and I always used to do it wrong by choosing what you chose. Im still confused as to whether Im correct now or not!LOL I chose D. I hope it's correct. It would be if:
1. Zaki doesn't remember right and W was just the weight as in the 2015 question
2. Option D said 'force on Earth from book"
I guess I wrote 6 in this one hmm... didn't know how to solve it. but what I do know that 3.5 becomes 3 +3 +1 ---> 7.8
3.5 in top half 3.5 in bottom half = 7 + 1 central = 8
No thats not how its done,the ans was 3.5.You dont round up to nearest integer for maxima,3 at the top 3 at bottom and one central so total of 7.

What about the graph question which was a friction less slope?
I did A at first too but if you had looked closely the point S was at lower level than the original point from where it started so the loss in pe was converted to Kinetic energy hence the greater speed.
"That q about sqrtmgh was C, the sum of m sqrt 2gh1 and m sqrt 2gh2"
and "the The one about air resistance was C, the scary looking equations. I got it wrong"
How can it be C both of them?
The question with the 10 revolutions per second and we had to find wavelength of wave ??
What about the phase difference question?
Yay these 3 questions are correct!
i am absolutely sure that the second slope ( the one in which the ball fall) was more steep in the picture, as well as the graph of 2nd slope was steeper than first onesI did A at first too but if you had looked closely the point S was at lower level than the original point from where it started so the loss in pe was converted to Kinetic energy hence the greater speed.
what did you chooseWhat was the load unload graphs answer?
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.
