    What experiment could you do related to the photoelectric effect ??
    not an experiment but a long question on that topic. like how does the photoelectric effect explain the particle-like nature of light

    I don't think Ekmax= hf - workfunction 6 marker question will come us because the textbook says 'the details of this experiment are not required for your AS exam'

    my weakest topic, I hate it.
    I agree, Im hoping the essay question will be on something else

    So if photoelectric effect is the 6 marker then would you be expected to explain the processs of it

    Wait for the internal resistance calculation, shouldn't the terminal pd be constant, so voltage is always the same?...

    is that voltmeter measuring the voltage across battery

    Yes, I'm a little confused on why terminal pd ever changes though...

    Think of terminal pd as = voltage (IF NO INTERNAL RESISTANCE)
    Same thing in that scenario.
    If there is internal resistance however then terminal pd is = voltage to circuit AFTER lost volts on internal resistance.

    So if internal resistance is higher than terminal pd is changing and is lower.

    how they got the graph would be a start when resistance isn't even a factor but that's what they're changing ahh

    Your changing the resistance so you can get different currents and voltages, so resistance can be plotted where the internal resistance is the gradient of the line.

    voltmeter is not measuring lost volt. it is measuring the voltage at the resistor. however, as the current increases, the lost volt inside the battery also increases so the pd across battery terminal decreases. and therefore, the voltmeter reads lower value of voltage at the resistance. Again, this is because more voltage is being used up in the battery (increase in lost volt). Did you get this?

    Does anyone know the difference between writing the strong force/nuclear force/interaction? Is there a difference? (same goes for the weak one)

    Strong nuclear force/strong interaction are the same. nuclear force is incorrect because you are not stating strong or weak.

    Strong force binds quarks together
    Residual strong force/strong nuclear force binds proton and neutrons together.
