    Could you explain how you would do this?

    is there anything else about derivations that we need to know other than that?
    How did you get from the second to last to final expression?
    The third is simply because there is three coordinates?

    Could anyone pleeeease explain to me how you know what the nature of radiation emitted is from different things? E.g. moderators nucleus, spent fuel rods, fission fragments, nuclear reactor core?

    Thank you. How would you plot a graph for it though? Would you have 8 different masses?

    Why on Earth were the neutrons included in fission calculation in June 2011, but not in June 2014? When would I know when to include it or not?

    These are the ones mentioned in the specification:
    Rutherford's scattering experiment
    electron diffraction
    determining different types of radiation
    determining value for absolute zero

    I've been revising all day phew
    not very confident, I was off college for almost all of unit 5 because of a relapse in illness
    its amazing how much our teacher covered in 7 weeks and then didn't bother to help me out lol
    i think I might be okay though, nuclear stuff is good for me
    turning points and gases not so much >3>

    all mass does

    No they don't because neutron on its own isn't bound to anything

    Can you explain why the mass of the neutron was included in June 2011 but not June 2014 please.
    Both had neutrons on either side of the equation.

    That's not a binding energy, that's its mass-energy equivalence. The binding energy is the reduction in overall mass-energy due to binding.

    in the question theyre talking about almost certain you used the masses to determine mass before vs mass after then converted to energy emitted
