Oh right! Thank youon P , arrow will be towards right, for N arrow will be towards left.
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!

Ahhh my gosh! Thankyoooooooooou!!! :'D(a) (i) A & C
Treat A to C as a straight line and forget everything else. The resistance will only be R.
(ii) B & X
The total resistance in parallel here is R/2, so the resistance at any point there is R/2.
(iii) This is equal to the total resistance in series + total resistance in parallel, that's 2R + R/2 = 2.5R.
Definition sheet for As physics pleaseeeeeeee? I'm freaking out. Help
well its easy . look, continue the line of sphere B till the time (t) where the graph of A starts to descend. ! then ,contiune the graph by ascending the line wid constanst positive gradient , now the tricky part is , that till where the gradient must b kept constant, for this, u have to consider the change in velocity of sphere A , like, it changed from 6 to -3 which makes it 6+3=9 (change in momentum) , same way , sphere B starts wid Momentum -4,Oh yes, the electric field. How stupid of me x_x Thank you! Could you help me with this one?

can u pls say what year is this..i got an answer and need to check if it is rightor wrongView attachment 11456
how do you find Q 2 part b???
why do we assume plus minus 1 digit means 0.01, for example why cant it be 3.05?um first of all it was question 1 a ii....ok and yes the answer is 2.08 because as u answered in the first part a change would be +or- 0.0205...so maximum vlaue must be 2.05 + 0.0205=2.0705..then he said in the question that there is +or - 1digit..so 1 digit means 0.01 so 2.0705+0.01=2.0805..wish u understood.
because he gave you the voltage which is 2.05..so when he says 1 digit, it means to start count from the end which is in this case the 5..so its is 0.01...maybe im wrong but this is the way i was teached and it worked!!why do we assume plus minus 1 digit means 0.01, for example why cant it be 3.05?
June 11 paper 21can u pls say what year is this..i got an answer and need to check if it is rightor wrong
in series: Vtotal=V1+V2+V3 .... Itotal=I1=I2=I3 .... Rtotal=R1+R2+R3..What is the difference between cells arranged in parallel and in series!!, In series I know just to add them up and get the final emf, but how parallel work?
ok the question asked for the component of the weight DOWN THE SLOPE...so resolving the forces gives us the W component as mg sin (theta) so m=850kg, 850 x 9.81 sin (7.5)= 1088 so about 1090NJune 11 paper 21
Yes, I did! Thank you so much! Also, what is eVand MeV? I'm afraid I haven't ever come across these. http://www.xtremepapers.com/papers/...nd AS Level/Physics (9702)/9702_s10_qp_23.pdf Q.7(b)(i)well its easy . look, continue the line of sphere B till the time (t) where the graph of A starts to descend. ! then ,contiune the graph by ascending the line wid constanst positive gradient , now the tricky part is , that till where the gradient must b kept constant, for this, u have to consider the change in velocity of sphere A , like, it changed from 6 to -3 which makes it 6+3=9 (change in momentum) , same way , sphere B starts wid Momentum -4,
so by keeping constant the change in momentum, we can calculate the final momentum of sphere B ,
X-(-4)=9 , answer will b 5 , so the graph will ascend till the momentum is 5 , after which it will continue as a straight line wid zero gradient , hope u got it
Oh yes, the electric field. How stupid of me x_x Thank you! Could you help me with this one?

eV = electron volt, and MeV = mega electron volt.Yes, I did! Thank you so much! Also, what is eVand MeV? I'm afraid I haven't ever come across these. http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s10_qp_23.pdf Q.7(b)(i)
and wont you multiply that value by 1.4 after that? :OeV = electron volt, and MeV = mega electron volt.
e = magnitude of charge on electron = 1.6 x 10^-19. Units = C.
V = voltage. Units = J/C.
When they multiply, the units of C cancel out so you are left with J, meanings its a energy quantity. The M just means mega (10^6).
So if you want to calculate for example, the value of 1.4 MeV, then it would be:
10^6 * 1.6 * 10^-19 J.
