    Physics 1 was really hard.
    Physics 2 i found ok
    Physics 3 i mucked up. (astro)

    Ok, can remember what paper, but it gave 3 types of force, gravitational, electromagnetic and sommet else. Anyway, what did you put for the examples, i thought it was a stupid question, and didnt really know what to put.

    The other thing was the moments question when it asked for the other horizontal force, i put it at A. Then use moments and whatever to find X and Y, i got
    X = -184N
    Y = 126N In the left direction.

    I was unsure cos it sed the force X is a tension, but resolving shows its actually a compression.

    For Gravitational I put Weight
    for EM i put Electrostatic Repulsion
    For Nuclear I Put Strong.

    i think the value on the x axis was something like 0.45 and the y axis was something like 0.6 though i'm not sure,

    can anyone explain how to do the density question please

    your values of x and y r out by a factor of 10
    they were 1800 sumfing
    and y was 1500 sumfing

    if u mean the density questioninvolving lead,
    the thickness was 7x10^-4

    i was actually referring to what dormonkey asked, something like "how did you do the density question", so i asked "which density question"

    anyway, how did you get your answer for the thickness of the lead?

    anyone else notice the mistake in Unit 1 on the Rutherford scattering question? It refered to a "small, massive nucleus"!!!
    surely this must be wrong! :eek:

    yeah i didn't really get that either, but they said the exact same thing later on in the question, so it couldn't have been a typo, could it?

    "massive" means it has lots of mass, not that it is very big
