To be honest i am not sure, i guessed that one and by accident put the one that didnt show anything ... I only had 10 second to think for that
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

What did everyone got for explaining why one graogh is better than other or something like? All i put is that straight is better because it shows linear relationship which means that they will be less error on the value found either using gradient or y intercept etc hence this will make it more accurate ... I dont think if this is rught though
Yeah I pput something like that saying how you could use y=mx+c

Wait do you mean there was a grapgh of diodes but one showed V/I and other showed I/V
4. 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

got the same

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
10. (Original post by 11234)
50 for an A maybe?
Noooo, i reckon a lot lower. Even my physics teacher thinks it'll be like... 65% for an A
11. (Original post by 83457)
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
14. For the mcq with K0 did anyone put B
15. 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....👀
16. I got 2f for the frequency mutiple choice
17. Hitler reacts to paper 2:https://www.youtube.com/watch?v=ztc43dC0320
18. did anyone get f/square root 2 for the a mcq
19. (Original post by Sam Webb)
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.
20. what did everyone get for the diameter of the wire (the question that contained a zero error)
