    i wrote protons and in how to make it positivly charged just add earthing negative electrons will escape and go through the earthing and it will become positivly charged

    Yaaay same ! what about the positive charges i named them prtons not sure :S

    haha yaa mostly :S

    its is 9.333 because the highest speed was at the straight line where it was constant :) you had to try them all

    yaa :D i left its as 6.66 :P

    16/20 :P cause you have to divide it by 2 so around 32 out of 40 70/80 and 35/40 just pass paper 6 and you will get it :) the curve is kinda of low this year

    yup :D it was 1.14 or smthn :P i did the KE = MGH so it was 1.14 or 1.4 forgot :P

    i was talking about an A*

    nop 1.14 or 1.4 forgot smthn like that you have to do MGH = the energy you calculated at the beginning

    Physics P31.. How did it go?

    yup same hahah well i hope they are right :S i freaked out in the exam though it was hard i got the energy in solar pannel 22500 and the power around 48 or smthn in 40's the height i used GPE and i got it as 1.14 or 1.41 smthn forgot :p the first question i choosed 1.8 because it was the...

    no getting medium A's so around 33 or more paper 1 65 and more in paper 3 and paper 6 16 or more just to be on the safe side can be lower though

    ya ohh :S its ok 2 -3 marks max

    *** was that(physics paper 3)

    ya its the same dont worry its right :D

    *** was that(physics paper 3)

    ya probably you will some marks since wider means more area :)

    the Pistons i wrote that it need mor force because more area and pressure is constant so the force increase the reason it moved less i wrote it had much more area and that it required more force the air bubbles in the oil will cause the oil to become compressable hence reducing the efficency...

    you add the resistance that awas in parralel and then use V = IR so v = 6 and I is equal to the current in you find in B + 0.8 and R is equal to the current in parralel X the Resistor we need to find i got 1.8 Ohms
