    I estimated the wavelength of ultraviolet to be about 670nm and used delatE=hc/lamda to find an estimate for the difference in eV. Pretty sure it turned out to be E1 to E2
    Ultraviolet waves have way more energy than photons so i chose the one with the biggest gap which I think was E2-E0 (if that was an option, which i cannot remember too well)

    The graph question about changing velocity time graph to accelration graph .... I thought for this one that since the gradient of velocity time graph was curve, it meaning that that it was decreasing accelration so i picked up graph that was showing accelration being curved and reaching zero eventually

    What did you get for the IV graph

    The one with circuit shown, dioide and resisitor?.?

    I remember guessing the second largest 83... option. Was there a choice greater than 83000? If 83000 was the largest then I lost another mark :/

    Yeah you had to work out time using suvat and then plug it into f=mv/t

    Isn't the falling object graph the one with constant acceleration D?

    To be honest i am not sure, i guessed that one and by accident put the one that didnt show anything ... I only had 10 second to think for that

    What did everyone get for the IV graph with the resistor and diode and what do you reckon 56/69 would be

    WHere it increases from an x intercept linearly right? What do you reckon you got, Im so scared about boundaries now

    What did everyone got for explaining why one graogh is better than other or something like? All i put is that straight is better because it shows linear relationship which means that they will be less error on the value found either using gradient or y intercept etc hence this will make it more accurate ... I dont think if this is rught though

    Apparently it was a V-I graph not an I-V graph so it wouldn't have looked like A if that's the case

    Yeah I pput something like that saying how you could use y=mx+c
