    I know, but when writing an electron the top number above the e is 0 and the bottom number -1, I just meant the number where the proton number usually is.

    Basically I wrote a +1 and not a -1 but only put e not e+
    I put:
    (1,0)n --> (1,-1)P + (0, 1)e+ + (0,0)Ve

    I think that's the same?

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

    Can someone help why does the positron have a 1 at the bottom??

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

    In the specimen paper it had a question with electron emission and it was given as beta minus not e minus. Since the spec paper is the closet thing to our exam I would e+ is correct

    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 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)

    Perhaps but just one question. In either case the frequency is quite high and I was under the misconception that microwaves have relatively small frequencies and high wavelength?

    I forgot this bit so probably lost 2. Looks fine.
