the hard part was finding the right value for a, since you have to use f=ma with force from your first answer and m from the back of the sheet, dont think you'll get any marks for that q tbh
You think so? I think that the hard part was knowing what to do with a, i found a using f=ma but didnt know what to do with it, hopefully i get 1 mark.

$\bg_white Once you got a, isn't it just basically v^2 = u^2 + 2as?$

Yeah it was, but i was too used to doing projectile motion and subbed a=9.8 and got a massive number despite having worked out the actualy acceleration.

Can you sketch the graph and put everyone out of their misery ?

I read that you can lose marks for writing too much. I've never had a problem in the past but in the exam I wrote a bit more than usual probably out of the adrenaline. All my stuff was relevant to the question but a few times I elaborated a bit on points that may have been unnecessary like explaining in detail for the superconductors questions. Am I likely to be penalised for adding too much detail (even though my response answers the question and contains all correct information)?
Losing marks for writing too much? Where did you get this info????

you don't lose marks for writing too much, but generally when ppl do they contradict themselves or talk about irrelevant points which makes you lose marks

Question number 1 guys: What did people do for the Hertz proving Max Planck's postulations? I hope I was right in talking about the spark being reproduced in a disconnected, broken conducting circle. You know what I mean.
