    I did!!
    (Original post by Bulbasaur10)
    I did! Also, as that was in P3, can I ask whether the lens question was asking you to describe how the image changed as the object got closer to the lens or as it got further away? I can't remember and it is freaking me out!
    Siiickk, thought I completely messed that up
    And ah, sorry P2 and P3 have basically merged for me :/ I think it was as it got further away but idek, either way I still probably got it all wrong because I didn't know how to describe it. I drew a ray diagram for it and described both of the images :lol:

    For that spring one it was 300 N because you had to times it by three to get the three springs
    yay! I got that! What did you put down for the units of spring constant, my mind went blank.

    Did anyone get 52 N for the boy doing pull-ups question?
    You couldn't of gotten newtons, the question was about power so you had to work out the g.p.e per pull up and then times this by 12 to get in a minute. Because Power is J/s you had to then divide this by 60 to get the power.

    Does anyone know the answer to the one about suggesting what the disc theory meant about other stars or something like that? I had no idea
    I didn't even know what the question meant I wrote "there are other planets orbiting stars" :lol:

    I put earth wire as it works in conjunction with the fuse
    Same think that was probably the only question I got right. However, people are saying its wrong. So maybe it just one of the 60 I got wrong

    That exam was hard!

    I think I messed up all the calculations.

    Did anyone remember getting these?

    600 Ohms for resistance
    0.015 Amps
    400 Joules
    100 Newtons
    84 Kg
    22 m/s^2
    I got the first three but messed up the last three!

    I can guarantee the fixed Resistance of Resistor A was 200 Ohmes.

    Yes, I took away 840 from the bigger number because you needed the resultant force in the equation. Paper was fairly hard.
    Thats what I did!!!

    For the question where there was a image of a spring and you had to fill in the 2 blanks what did you all put?

    Yes therefore you have to divide this by 2 to get the real distance right, and not the double distance right?
    It asked for the speed. It gave the time for it to go there and back, but only the one way distance so you had to double it.

    How? Bitesize says it's the earth wire?
    Could you explain it please, thanks
    you are both right but did slightly different papers! yes the earth connects to the casing but on another paper the question was 'What wire connects to the FUSE' which is of course is the live wire so dont worry you both get marks!

    I got 600 ohms for the resistance and 0.015 Amps for the current. What was the 400J question? I might have got it. I just don't remember putting it. What is the question for the 100N? I got 84kg but I got 12.02m/s^2 for the last one.

    I think the answer was elastic potential. The question was something like: "When work is done to extend the spring, the energy is stored as .............. ................"
