    I did not finish about 13 marks of the paper.
    What you guys think the grade boundary for this year would be ?
    Am i possible to get an A?

    I found it easy and hard. But then my friends found it quite easy. So I don't know.

    So what did you get for the moments one?

    Ahhhh, I think I did it right then! That's good!! What fluid did you get that the student was using? Corn syrup?
    I think so can't remember - Whichever one had a viscosity one of about 1.4

    It felt easy overall although I still didn't do well, they'll probably put the grade boundaries right up

    How did you get 157? I got something in region of 4-500... Do you have a copy of the question at hand so I can try see how it went?

    Same I did the 1.4

    Well because it is a significantly larger distance from the base of the post, where you take the moment from. It is going to be significantly smaller than the 870N value. Considering a basic ratio, it would be much smaller than 400-500.

    That might be right, it depends how you rounded the numbers that you used

    yeah... More time and i would have notice the stupid mistakes i made!! Like the one about calculating what the fluid was!
    rhe fluid will be my spunk in your mums mouth

    The efficiency one, you know the velocity to be 0.4m/s so in 1 second it rises by 0.4mYou can use E=mgΔh to find out the energy (which if also the power) then P=VI (or something like that) and use the two powers to find efficiency
    for this one, times velocity by the weight to get power, then times v and i to get imput power and find efficiency. ENERGY IS NOT POWER

    I'm aware that Energy is not power...

    However, if you're calculating the energy transferred across 1 second then that would be the same as the power.
    I think the mass was 0.05kg and the velocity was 0.4ms^-1

    So velocity x weight = v*m*g (your calculation) = 0.4*0.05g

    E= mgh, when travels 0.4 m in 1sm E = 0.4*m*g = 0.4*0.05g

    They are the same calculation

    What was the efficiency? I somehow found 1.7% or something which is most probably wrong...

    I think it was around 78.9% or something like that? I may be wrong. Anyone have an unofficial markscheme?

    How was the efficiency question done? I found a value for power and a value for gpe.. There was no time give so I was lost..
