    A2 physix p5!!! help me pweez! :(

    While calculating uncertainity in log you should subtract the highest value and lowest value and divide it by 2. For eg: if it is log(4.0+- 0.2) then uncertainity would be[log(4.2)-log(3.8)/2]. Hoped it helped. If you have any problems you can ask me freely.

    Physics: Post your doubts here!

    yeah! mark scheme says to construct this equation and says nothing about statement. so i think we should construct the eqn and state the relationship. This is all we can do.

    Physics: Post your doubts here!

    I think after writing this eqn we should say that that are directly propotional and if one changes it affects to another..

    Physics: Post your doubts here!

    to calculate the error in gradient firstly calculate the gradient of worst fit line and subtract the gradient if worst fit line and the gradient of best fit line. to calculate the value of rho in qno 2 d firstly re arrange the equation to R/L^2=rho/V+Ro. where Ro is constant. R/L^2 is gradient...

    Physics Paper 5 tips

    No, log is only used you have been asked to calculate unceratinity in log and ln(mostly when powers are given). in other cases like squares you should not use log. May be it helped. ;-)

    Physics Paper 5 tips

    We have been taught by this. Firstly calculate valie of log upper limit. then calculate the value of log lower limit. Now subtract these two and divide it by two. For eg: if it is 50+/- 5 then. firstly calculate value of log(55) now calculate the value of log(45) and now subtract...

    How was Physics 42?

    i think it was 50 or 80 pF.

    How was physics paper 4

    There were lot of descriptive questions, where it is easy to cut marks. so i tjink gt would be around 58-60-65.

    any1 good in graphs??

    yup. In chemistry it can be a curve too.

    any1 good in graphs??

    It can be a curve too. Bit in physics most of them are line. except some of them.
