# 2016 Official AQA New Spec AS Level Physics Paper 2 - 9th June 2016 watch

1. 0.62 for moment question anyone ?
2. (Original post by money-for-all)
phase difference pi/6 ?

for mcq
I got pi/4?

10 ohm resistor connected to battery. Battery cinnected to voltmeter in parallel. When switch is open voltmeter reads 1.45. When closed it reads 1.26. Calculate internal resistance of battery?
that gets me 1.5 ohms, does anyone know if that was an answer? (for the last question)

What did you guys get for moment question I got 0.73
5×(12×10-2)=f × 8×10-2

The multiple choice one? Think I put 4lambda
is it not lambda/4? I thought cause the mass of alpha particle is 4x that of a proton, it would be 1/4 as its inversely proportional😁

Yes it was, i got 1.5 ohms as well

8. Any ideas on boundaries
9. seriously did AQA forget optics was on the spec

0.62 ?

5×(12×10-2)=f × 8×10-2
But I assumed the centre of mass was at the centre of the ball so surely the distance of the ball would be 12+5/2cm

5×(12×10-2)=f × 8×10-2
You had to take the centre of the ball as the line of action didn't you? So the radius length was added on

chill it with the optics bruh

thats what i got
15. Ugh i didnt understand what that one evn meant, i did (100/114)^2 but its probably wrong
16. i put 100w even though i worked out it to be 114w due to one of the pieces of info that i used being to one sig fig. do you think that is still correct?
17. (Original post by Lola1244)
thats what i got
i got the same
18. The strangeness could be +/-1. so I think there were two answers to the question
19. 51 for A?

Think you had to use lambda = h/mv. With an alpha particle, there are 4 protons/neutrons, so the equation turns into lambda = h/4mv, leading to 4lambda = h/mv.
