    how did you guys draw the output on the diagram (when the magnet is rotated).
    I did it so that the voltage was doubled, so the line stuck to the same pattern but went higher and lower...

    Yeah I was thinking of putting that but I wrote about vasoconstriction and that the blood wouldn't be at the surface as you're trying to keep warm!

    Probably did get that wrong!
    For the pale fingers and toes I wrote; vasoconstriction occurs which makes the veins narrow, this stops heat energy from the blood stream being lost to the surroundings.
    I think if you write about vasoconstriction and what it is, then you should get the marks.

    If any ones still wondering the last physics question would have been 275kv and 400kv as they gave you the ratio 11/16 and 275/400 simplifies to 11/16.

    Oh damn! I think that's a bit stupid considering both the answers where in the article!
