    The last question was weak nuclear right?
    Yeah, nuclear decay is always weak nuclear (I hope).

    Can't remember the answer but the method was:

    2 x the rest energies
    Convert to joules
    Divide by planck's

    This was by far not an "easy paper", and people who are saying it was are just those 1 or 2 geniuses everyone has in their class. Not only did you have to revise the FULL spec (eg Stopping potential) but you had to apply your knowledge across the whole exam. Also there was like 2 questions on Particles? (Discounting the Photoelectric effect) and Particles is the easiest topic of the lot (Amirite)? I think the examiners know the particles topic is just a revision exercise hence why they kept the easy questions on there at a minimal.
    Tbf, I don't think examiners intentionally try to avoid easy topics, they probably just want to use interesting questions to see how students respond and if they can think it through. And by the time they had done all of that, they probably didn't have many marks left for particles. You shouldn't worry either because the specification will be covered across both papers, just what you prefer might not come up in both...

    Have you seen paper 2 on the second set? Its virtually impossible and by no means is the multiple choice "easy marks".
    Not yet no. But if its anything like paper 1 second set I can imagine. That thing put me close to tears last night. I got to the point where I thought, "is it even worth me turning up because it would be better to have no AS Physics than a U or something".

    Glad I did go though, because the real thing, IMO, was nowhere near as bad as the specimen and so I expect the same for the real paper 2 as well.

    Calling them easy marks was perhaps a bit of an exaggeration, but if you find the answer and then look at the options, I find it make multiple choice much easier as it confirms your answer you got it wrong. The practical questions usually require little knowledge, only how to carry out practicals "practical skills" which means they could be a gift (or hellish if you don't know how to practicals, uncertainty well).

    You also need to divide the total energy by two to find the frequency of 1 photon by using the energy of one photon

    Yes same that exactly what I wrote and I just wrote the wire stretches thats fine right ? Theres not much words you could use , I was going to write elasticity but like that wouldn't work.

    And Yes I wrote ductile , Also I don't think there was a definite answer because in the mark scheme it said state your reasons why so as long as its logical to some extent it should be ok. But Yeah hopefully we did well on the QWC and well the whole paper haha
    Yeah. I don't like this whole holistic approach to marking though. When I was marking past papers I found it very hard to give myself an accurate mark and I bet ductile is one of the required words. Ah well, too late now.

    Thats what I put so hopefully. Only one mark if it isn't anyway

    Multiple choice is one of the hardest elements in reality as if you do work something out incorrectly for one of them, your answer will be one of the 4 options. And you'll go on your merry way thinking you've aced then crying on results day. Be careful lols

    Momentum increases.

    It stated that the air was a higher speed after it had been heated up in the engine.

    momentum = mass x velocity

    A constant mass but an increase in velocity gives a greater momentum
    The question specified that the speed stayed the same. The air changed direction so the velocity changed so that caused momentum to change.

    Pretty sure I read that it was the frequency of both photons. If you'd divided total energy by 2 you'd just end up at where you started.

    For the last question on the helium nucleis annihalating, id anyone get something x 10^42 (10 to the power of 42) for the frequency?

    Think you forgot to convert to joules haha should have been something along the lines of x10^24

    Wasn't it the frequency of both no need to divide by 2

    I don't want to say you are wrong because I cant remember the question exactly.

    But I remember the question saying it left at a higher speed that is entered, quite vividly. I think you may have the question mixed up?

    Or I do, but lets try find out if someone has the question
