yeh put that :-)

good

sorry, the comment about the marks was aimed at the other peron, altho i quoted you

rosie

aha yes!

Physics 1 was really hard. :frown:

Physics 2 i found ok
Physics 3 i mucked up. (astro) :frown:

does anyone remember the voltage and current values for point x on that internal resistance question

nope sorry

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

yeah those values are right.....

which is the density question?

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

density question on phy 1?

Oh, bollocks. I read the length from A to B as 1.6. Thats so annoying :mad:

sorry m8, i know how it annoying it must be

which is the density question?

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:

don't know bout you lot but i found paper 2 really hard (the thermal stuff) unit 1, and 3 particle were fine!

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?
