    Oh yeah, box falling question was 40N right? 50N (gravity)-10N(air resistance)=40N (unbalanced force). Eh come on, that must be right!
    Yeah but I jsut did weight of 10kg times accel of 10m/s/s = 40N. i think that is ok.. used the 2nd law of motion f=ma

    Was i correct in saying the falling object in the electric motor helped to turn the coil, wich induced current and lit the bulb?

    What did people get for the momentum Qs?

    The one at the bottom of the left page :confused:...

    Well I'd hope so because thats what I wrote as well. In any case, I don't see what other answer you could put, apart from maybe going into a little more depth and saying it cut magnetic field lines.

    AQA paper


    Momentum Q, i got 11.25 and the force was 112.5N i think. Normally i dont mind momentum Qs but that one was weird.

    The sun Q's answer was that the very dense substances found on earth now had to of been made wen a previous star collapsed in think. that proves our sun was created fromt the dust given off from the previous one i think.
    Only 2 or 3 marks anyway.

    The magnifying Q was really annoying for me. Couldnt remember it at all and it was a 5 marker.

    What kind of AQA is this?

    Modular? Coordinated had no nails involved.

    Ahhh this is confusing, all different exam boards/tiers in one thread

    Anyway.. I did AQA.. Higher.. it was ok. That nuclear stuff confused me, so I made it all up. I made up some of the formulas towards the end too. And some other stuff, but I think I did ok.. maybe. Anyway, it was the last exam, so I'm happy Probably won't post here again until next year now

    Did AQA Higher (non-modular)- wasn't too bad.
    Generally content with it, though I wiffled my way through a couple of questions and completely hashed the alpha particle one due to general foolishness.

    Yosh! That's science done then...well, assuming I've done reasonably well. I'll have to retake if I don't get an A or A* *sigh*.
