Any one can tell me how to start with paper 5 analysis? It's really confusing
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

22) Volume = mass/density = 3.5 x 10^-25 kg / 9.2 x 10^3 kg m^-3
= 3.36 x 10^-10 m^3
So, answer is C.
thanks very helpful
No problem
Hi please help me solve this, 71. answer is B but how can it be 20 J? I tried 8=4+Fs but it doesn't work
The change in energy is 4 joules (as 8 -4). So the change in kinetic energy will be twice = 4 x 2 = 16 joules.
But remember this is the change, not the final energy. So the 4 joules will become 16 + 4 = 20 joules.
Hope this was helpful. Sorry about the delayed reply.
hey there how r uHi everyone, AsSalamoAlaikum Wr Wb...
To get things organized in a better way, I am making this thread. As othewise, some queries remain unanswered!
So post your PHYSICS doubts in this thread. InshaAllah other people here will help me and you all.
NOTE: If any doubts in the pastpapers, please post the link! You can find links here!
Any Physics related notes and links will be added here in this post. Feel free to provide the links to your notes around the forum, or any other websites!
Thanks!
Jazak Allah Khair!

question no. 6, 9,15,25,33
to calculate the error in gradient firstly calculate the gradient of worst fit line and subtract the gradient if worst fit line and the gradient of best fit line.Can anyone please help me out in Q2.c.iii ?
I have found the gradient, which is 0.56. But I am having difficulties in finding the errors of the gradient.
The absolute errors that I've got on the table are: 0.13, 0.08, 0.06, 0.04, 0.04 and 0.03.
Please help me how to find the gradient errors!!!
And also Q2d!!!
PLEASE!

need help here http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s07_qp_5.pdf Q.No.2(a)....after we convert the equation into R=(Pl^2/V) + Ro ( P= rho) what do we write as conclusion???
The change in energy is 4 joules (as 8 -4). So the change in kinetic energy will be twice = 4 x 2 = 16 joules.
But remember this is the change, not the final energy. So the 4 joules will become 16 + 4 = 20 joules.

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.
