    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

    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?

    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.
