    Nope, missed factor at the end (I got this and corrected)
    What did you end up getting? A fair few in my college on one or two said 1.15x10^-19 (I think it was ^-19 anyway)

    For the limitation I put dampening due to air resistance? Also on the MC, for the pendulum which one would have the largest amplitude? Overall I found section B okay, but the MC tricky.
    I put the one with the same length as the driver since it would resonate. B if I'm not mistaken.

    what were the numbers involved in the first multiple choice question and what was the answer?

    If my momentum formula V was completely wrong (as I thought N was the mass of the original) how many marks would I get for the kinetic energy one? Which I couldn't even prove but done loads of working.....

    What did you guys get for the question about the height above the surface of the Earth on like q11 or 13 of MC? I ran out of time so I just done A

    old momentum = 0
    new momentum = 0
    VN+mv=0
    because the value of v and V already account for the different directions.
    but the mark scheme will probably not care
    V is not a magnitude, it said Velocity V
    That's just because they don't want to use vector notation in A-Level physics. The velocity V acts in the direction < but has magnitude V. They've told you this by the diagram.

    It did say velocity I agree, BUT the arrows were in opposite directions!
    ^ Exactly.

    If I recall correctly the answer was 3.6*10^7, I don't think it was A, sorry

    what did people get for the one with the right angled triangle in a gravitational orbit?
    I think I put 4F. Used F= Gm1m2/r^2

    Can I say for the disadvantage that the electrical energy is costly? What about the electron one when I said its mass is negligible

    Yeah, you had to subtract the radius of Earth from the geostationary orbit (4.23x10^7) to give 3.6x10^7 metres.

    I think I put 4F. Used F= Gm1m2/r^2
    The distance between then was sqrt(5) so the Force would be 1/5 of the force felt when they were closest together, giving an answer of 5F

    (I think)

    beta releases anti neutrinos which take away some of the energy
    I don't know what the right answer is, but what I wrote was that the electron produced will travel at high speeds , electrons are of incredibly small mass, so i said the electron will act as a wave

    I thought the thing with the neutrinos but isn't that still applicable to the formula because the two products still carry away all of the energy in the form of ke?

    Ah right, I think overall it wasn't that bad though (the multiple choice).

    that's correct. I would help but i don't think i got them all right and i don't remember what question was for which number

    Could someone please reply to this.

    For the first question the value of the resistor and time constant depended on the capacitor from the previous graph, so I worked all these out. However when I checked through I looked at the graph and worked out the capacitor to be very slightly different, will I drop any marks for not re-correcting the time constant and resistor or will it be fine?
