oh damn!!.....

the paper is ok. i found number 2 hard...the other stuff is challenging but manageable
6. same as kosy91 its not too bad just glancing at it, not great either but doable i think, at least it doesn't have stupid questions where anything could be the answer like the spec paper.

cheers for the paper though need any questions i can get
7. Looks quite easy? I'm on AQA though so maybe it doesn't cover all the same stuff?
9. For the multichoice first page I got the solutions;

1. B
2. A
3. B
4. C
10. i also got
1.B
2.A
3.B
4.C

then section B 1
a)1
b)1.4 x10^-2
c)2.1 x10^-2
d)1.4 x10^-2
11. How would you explain the shape of the graph fo 2b(i)?

well the direction of the magnetic field from the magnet depends on where the N and S are, since its spinning this keeps changing therefore meaning the direction of the induced current keeps changing, switching from one direction to another if that makes sense?? its the same reason we have AC electricity

3. B
4. C
For section A i got

A
A
B
C

T=RC

1x10^-3/1x10^3 = 10^-6 F Therefore A is correct surely?

Or have I missed something??

i did the same first but i think it comes out to 1microfarad not 10

so if you use C=Q/V and use the 1 microfarad as capacitance you get 10V

You guys, don't you think you got question 3 wrong? An Alpha particle has 2 protons, not 1. So its supposed to go:

1.B
2.A
3.A
4.C

hmm i would say not as it says the electric charge as though referring to the thing as a whole not just the proton though i get what your saying, quite a few things on here are ambiguous

The "whole thing" is 2 protons and 2 neutrons. Therefore the charge is not just that of one proton, i think

aye i get what you mean just not entirely what the question means as technically it would be whatever it said on wikianswers but the question makes it look like for that specific question that the overall charge is the one given and therefore the one used

meh who knows hope we get better questions tbh
Live long!
21. keep the answers coming ppl!
