Haha I said increased as well.

what was q11 of light and matter?
it was the one asking about which excited state the electrons in the atoms were initially in

i put the initial excited state as the 3rd one. is this correct??
Nah it's the 1st one isn't it?

It absorbs, so it must be in a lower state.


FML EVEN MORE!!!

What was Q4 (diagram ??? )
you had to mark the direction the force on the side UV, or whatever it was, on the diagram of the motor

oops, i mean it was the one where you had to draw the magnetic field lines through electromagnet

For the transformers coils question I wrote 480000 or something, then at the very last second I crossed out the last few 0s to get 480. Do you think I'll be able to get that mark? the crossing out looked really dodgy and the working is all wrong.

i don't think they're up yet,
i think that other guy who said he had itute solutions was trolling, or at least i couldn't find the solutions on itute myself

Lines up from the electromagnet and going around and back into it at the bottom?
