# 2016 Official AQA New Spec AS Level Physics Paper 1 - 24th of May 2016 watch

1. No basically the voltage in parallel is the same therefore the potential difference between the two sides will always be 0 as the volts are equal in parallel. Even if it is replaced by a battery with significant internal resistance the difference in volts will still equal 0, because in parallel the voltage is the same.

Question was
1.5v battery is replaced with one with significant internal resistance. explain why the value on the voltmemter at A and B doesnt change

I got 0.79 as well
I got -60.% point something

I guessed that one and just put it'll always be zero think I'll get a mark? That was the only question I was unsure on

You should get at least 1 mark for that (i think it was out of 2 marks)
7. Sorry if people have already asked, but is there an uniffivial mark scheme?

Sweet! Also what did you get for the stopping voltage or whatever it was called?

What did you get for the percentage change in the diameter of the probe?
I got -60 (point something) %

For the stopping voltage i did my previous answer (the maximum kenetic energy) devided by the charge of an electron however i'm unsure.

Pretty sure thats right

I completely screwed that up, got ot wrong and still don't know it

That's what I did so that's makes me a bit more confident

I put A and D, as an elevator wire cannot stretch. And D because a bungee wire cannot plastically deform, and must stretch easily
I put A for the lift too, but thinking about it I don't think you could use a brittle material. Theres a reason why the cables aren't made from ceramic...
18. Part of the unofficial mark scheme has been posted in another thread

That's the link to it ^

Pretty sure it was B for lift and C for Bungee.

A is too brittle, will snap the second someone steps in lift, needs to strain a little to accoint for weight, but not to much.

C for Bungee as it strains and won't snap easily. Also wont strain so much thay the person hits the ground, which is what would happend with D

Yeah I agree does anyone fancy comparing their answers privately with me or something? Desperate to speak to somebody about the paper!
