    I think it also required use of the "130J" they mentioned.

    Yeah I added that too, not sure how important it is. I guess it might be one of those awkward underlined sentenced.

    For a turning points question, did you get a very small number for the number of muons per 1000 muons left after reaching earth's surface from a height of 10.7 km?

    I got 22.3 half lives occur and about 10^-4 muons remaining per 1000 muons starting

    it was 250. The time taken in the muon;s frame of reference was 3.2x10^-7s or something so two half lives had passed.

    It gave you the sentence with the data and asked you to explain the sentence

    Really?? Basically our school made everyone doing turning points as that's the only topic the teachers knew how to teach but also they felt like it was the easiest to pick up as it used stuff from the other units. those who got above a certain ums at AS level got to choose the other options for self study and I chose medical cos I want to be a doctor

    Medical physics is really hard if you're not interested in it! Yeah me either, but never need it again now!!!
    I hate medical physics! I'm doing Mech Eng at uni and it doesn't help in the slightest. Our teacher's claimed it was the easiest module though, so I just went with it. :P

    If anyone can put a copy of the questions on here and how many marks they are each worth that would be great! Thanks

    It phrased it in such a way that it wanted a definition specific to lead.

    If I calculate my 'best possible outcome' according to 2013 grade boundaries... I have the EXACT number of ucas points I need...... Cutting it fine.... Very fine indeed......

    I cant remember the question but it was something like this. Show that energy of (electron or molecules cant remeber ) is 4*10^-13 J

    I got 4*10^-14J

    How did everyone else do it.

    "with no change of state" is a pretty important part of the definition I think, when I've seen it before you need that for the marks.

    Nah it did coz it was secifically for the lead so you had to say it takes 130J to raise the temperature of a 1kg sample of lead by 1K without it changing state
