I wrote C because an increase in resistance meant less current will go through it I don't know
Yes C as a V=I x R so to achieve the same voltage with a LOWER current youd need a hugher resistanxe x

I'm not wrong!! Charge is measured in m/s squared because it is the flow of electrons!! JESUS christ did u revise anything
in EVERY textbook it says charge is measured in COULOMBS
JESUS christ did U revise anything

THIS IS WHY EVERYONE GOT 17M/S and this is why its wrong
170/10 ----------> 17m/s
You cannot do this because the line is not directly proportional on the whole line, it needs to be a straight line to take the gradient, you can't just take the whole line and work out the gradient and therefore the speed if its not a straight line as different parts have different speeds.

You have to take a section of the line from the steepest part. As this was straight you could work out the gradient.
The difference was from 125 to 170 over 2 seconds

SO 45/2----------> 22.5m/s
are you sure? i think you must be th eonly person who got that answer...

btw who has OCR maths tomorrow?

cool, i know i prob made a ton of mistakes on the paper, but we are all human and that is our nature. lets leave it at that peace
true.
5. How on earth is the max speed 22.5m/s?? The line was directly diagonal so all you had to do was do 170/10?? Can someone actually properly explain it please?

True, the topic is perhaps the most obscure of all of P2 tbh, but to be fair it was a ridiculously straightforward 6 marker. So much so I suspect there must be more to it.
