    Apparently it was a V-I graph not an I-V graph so it wouldn't have looked like A if that's the case
    Wait do you mean there was a grapgh of diodes but one showed V/I and other showed I/V

    What did everyone put for effects on % uncertainty. I put increase % u in area but decrease in extension because greater extension so more measurable and thus less % uncertainty

    No some guy commented earlier that it wasn't an I-V graph, but most people would have assumed so given the rush to finish, but a V-I graph. But I'm not too sure about this

    Im pretty sure it was a regular I-V so A
    Im guessing the flipped one might have been used to catch out people who thought its reversed because of the resistor

    I put the uncertainity increases on measuring diameter using calliper if it decreased and i couldnt think of second one so i put systematic error eill increase as accuracy is decreased :/

    Was that the SECOND smallest gap by any chance
    surely it was e1 to ground state because that was the only one larger in energy difference

    50 for an A maybe?
    Noooo, i reckon a lot lower. Even my physics teacher thinks it'll be like... 65% for an A

    did you round it to 10 or keep it as 3sf?
    I kept my answer to 3sf as it didnt state in the question any marks would be rewarded for the correct sif figs

    so 45 for an A what about 90 ums?

    The put the one that the biggest gap (ground state to the one above the ground state), I cant remember the numbers am I right?
    I put that as an energy difference bigger than the visible light means a higher frequency than visible light

    For the mcq with K0 did anyone put B

    This is what I remember...
    114W for power...
    2.11*10^whatever for ym in MCQ
    4 resistors
    10,000microvolts(or volts unsure)
    Y=mx+c so line graph was better for section A question
    Lamda/4 for alpha in MCQ
    f stayed the same in MCQ
    The rest is a blur....👀

    I think it asked "What is the maximum amount of components you can add without reaching maximum power" or something. So I imagine you have to round down or you will go over the max power.
    Ah, I see, I think I read it wrong then since I would usually round down unless something said otherwise - my bad.

    what did everyone get for the diameter of the wire (the question that contained a zero error)

    What was the last multiple choice answer, I had no time just but B down somet like 0.7??? But what was the real answer?

    You had to realise that UV has a higher frequency therefore a higher energy therefore the biggest gap
