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

I put:
(1,0)n --> (1,-1)P + (0, 1)e+ + (0,0)Ve

I think that's the same?

same here

Such mixed reactions from what I've heard... A lot found it "not bad", a lot found it hard, and just a few found it easy... Personally I found the questions to be a lot more abstract especially the engine one and the chocolate bar question compared to past exam papers. Definitely more "application" based physics (Which is good, but I REALLY hate it because I do well in tests that is fundamentally rote learning rather than applications). It was certainly better than the Specimen papers though.

Also, did anyone put C as the bungee cord? I put D down at first but I thought surely you don't want it to stretch that much and you want it to have a certain amount of strength rather than just completely stretching?

I reckon the boundaries will be relatively standard.

Also, did people get a small force for the Young's Modulus/Stress question?

Right, I'm going to create a skype group in order to get the unofficial mark scheme sorted? Send me a message of skype names and ill add you and then add you to the group

I also put C for the bungee cord and got something like 21 for the stress I think

we already have the google doc setting up

Would you still get the mark if you said beta plus instead of e+?

I was in there for a second and everyone was messing about?

For the frequency question of the microwaves I did this:
The wavelength was 12 cm => 0.12 m
f = c/wavelength. => f = 3 x 10^8/0.12 = 2.5 x 10^9 Hz
But that chocolate was kept in the microwave for one minute (60 seconds).
Frequency is waves per second so:
2.5 x 10^9/60 = 4.17 x 10^7 Hz (to 3sf).

Is this right?

I seem to remember get 23N

I don't think time needed to be included because it specified it was only "about a minute"

This seems like the best answer I have seen so far for warranting the full 5 marks. I dont even remember seeing that is was in for one minute. Therefore I got your answer before you multiplied by 60.

(Also I used 0.118m)
