    Physics Paper 52 - Discussion

    My planck's constant was 6.9x10^-34 Js What additional points did you all write for the first question?

    When calculating the error in the gradient do we need to draw construction lines to show that we calculated the gradient for the worst acceptable line?

    We write "Lg(T/s)" But the function itself doesnt have the unit. A graph of "lg(T/s)"and "X/m" will have a gradient with unit m^-1.

    In question 2 did you all write down units for log(a-x)? A log function has no units. Although the second question was easy a lot of people will end up losing marks because of this mistake.

    How was Physics P42

    The question on the graph of a comparator is an exact copy of the mj12 variant 2 question. There are many reasons for the photo-electric question however you cannot mention that "Emission is instantaneous" as the question already said that.

    How was Physics P42

    Yes the K.E was 9.something x 10^7 J The graph for the comparator was a square curve with maximum and minimum amplitude at the input supply. The attenuation per length was 17dB/Km The face was not upper or lower it was the side of the rectangle which was into the page. The reasons were: 1-...

    How was Physics P42

    I don't remember exactly. Kinetic energy was positive and potential was negative is all that I remember.

    How was Physics P42

    I didn't get that either. My Kinetic energy change was positive and I said the velocity increases as V^2 is proportional to Kinetic energy.
