    Hello! May I know why the 10^-3 on the y axis was not considered when calculating the gradient but considered when finding part (d)?

      gradient is for the line of the graph drawn, where the prefix is embedded/frozen in the y-axis. However in (d) you are asked to calculate the value of p, which required you to take antilog, including the prefix in the final answer. - Ms Lee.

      @@suitlinlee8903 thank you so much I think I attempted 3 or 4 qs, I had the same doubt and I was so confused about this. My mind was about to explode but now it makes sense, thank you soo much teacher!

    I was taught absolute uncertainties aree to be written to one significant figure only??? isnt it the case???

    @ 30:43 can we use under root with value of -1.43 on both sides instead of log? because still the answer is the same

    is ms wrong in (e) theta = root q (100/p). Shouldn't it be 0.10 instead of 100 since we are substituting p and q values into the original eqn so everything's in SI?

    Can we mark a plotted point as anomalous before drawing best fit if it looks very sketchy? Also, tysm for all the help

    @saviaidres1800 Рік тому

    If my line of best fit doesn't pass the ranges specified in the mark scheme, for all the calculations after it like the gradient and y-intercept, does that mean I lose the marks there too even if my methods are correct?

    why didnt we take 10^-3 while finding gradient at 13:25

    Hello miss,
    Can we use one triangle to get gradients for both best fit, and worst fit lines? Or do we have to draw 2 triangles ( one for each line ).

    • @ETphysics

      If you can choose a triangle that cuts through both lines nicely at the corners, then you can just use one triangle!
