8 is A I read the question wrong. 9 is A because only eddy currents are produced (not so confidant about this) 10 is A because a battery is a DC power source so there will only be a change in flux when it is switched on and off. So there is a current in X the whole time but only a current...

For q15 you use E=V/d then c=fwavelength to find frequency of 1.6 then follow the graph up to 2.5 then see that its aluminium. hence A

for no. 9 i thought of Lenz's law and i didnt think any current would be produced just eddy currents in the disc

1. C 2. B 3. D ? 4. B 5. D 6. A ? 7. D 8. C 9. A 10. A 11. A 12. C 13. D 14. C 15. A Im pretty confident about all of these tell me any you disagree with
