    The turning points question on measuring light speed.. Anyone do distance over time?
    Other than that it was fine, some answers i got:
    24V
    11m
    250 muons
    First box
    4.69x10^5V

    Apart from the 6 marker on nuclear and thermal. I thought that was good. I had literally 0 idea how to answer that 6 marker!
    I guess the graph of v against temp (or p against temp) is one of those things you remember or don't.

    Yes that's what I got! A very small negative.

    Think I put this in my calc:

    1.981 - 5log(25/10)

    Very close to zero I think it was -8.7X10-3

    Think I got all of them but not sure if they're actually right...

    Sweet, I guess the difference is just rounding

    The only two others doing TP at my school got them too, how did you find TP overall?

    I did medical. I hate lens equations so I know my answers is most likely wrong, but I got 0.19m. How about you?
    Wasn't the object at 0.25m? I did get 0.19m meters initially but realised that a diverging lens should have made the image further away than the object, so I fiddled around with the equation til I got a value over 0.25m, can't remember what it was though...

    Did you write about getting values for V when T is lowered incrementally and P is kept constant? And then extrapolating your line down to the x-axis to find absolute zero?

    Feel sorry for the examiner that gets my papers, both of my 6 markers had 20% full of scribble and crossed out
    We were supposed to do this?

    That sounds much more logical, but I expected to screw up the lens equation anyway. how did you find the rest of the medical paper?

    Yes, like 000alex' sketch but in words (also explained you could plot P against T as well), so with V against t pressure was constant and P against T, V was constant
