the one where the satellite was lifted 200km above earth radius, i did v =root/6.67*10^-11 * 6*10^24/(6380000+200000) if i recall correctly, so one line
oh alright, do you know why the one im thinking about was worth 3 marks? you literally do it in one line. For that 6 marker did you talk about how the planets are attracted by the sun and orbit it and stuff
sick, i got this and i did the other formula, v^2 = u^2 + 2 (a) (s), im guessing we're right cause we used different formulas and still got the exact answer. Edit: I got 4.19 so ~ 4.2 actually
does anybody know if my reasoning that the electric circuit wasn't closed (that 2 cm gap) means electrons cant be liberated from cathode and accel towards anode? i wrote that + electrons are - charge so its deflecting wrong way

1-2am, need a bit of beauty sleep tonight
btw, is there 10, 15 or 20 mc for physics? some papers have differing amounts

Reckon there will be a big question on MRI? It's pretty hard to remember mri compared to the rest
Sure but it's about the demand for labour too. I was always under the preconception that there's less demand for comp field than commerce field (haven't researched but I'm assuming that's the case)
