I got ABBBBDCAACDBDBA for the multiple choice questions - did you get anything different?
7.5 x 10^-14
9 x 10^8 particles
6.9 x 10^-14
How did you guys find it?

I have some numerical answers stored in my calculator, not sure which questions they match up to but they’re in order of the paper I think.

in the capacitors question, did you have to find the emf or permittivity? I heard someone on twitter say that they thought it was permittivity but you were meant to find emf. May have gotten confused cos they have the same symbol. Does any1 remember?

I got Max resistance was high at around 8000 ish ohms can’t quite remember what on first 6 marker. Time period distance from start of rise to next start of rise. Therefore f =1/T. I think time taken to travel in the refraction question was 3.6x10^-10

Definitely permittivity. The follow up question was about permitivity

Yes that's what I got for the refraction one. You had to use the hypotenuse didn't you since it wasn't actually travelling directly downwards? Quite a lot for 2 marks though I thought...

Yeah. I only realised with 2 minutes left to go and speed calculated it hahaha. I originally had it in the original direction of the light, without considering the vertical component. The word depth was bolded so I just can’t read apparently

Unless I'm mistaken lol.
