    'C' comes from the equation of the line x=c, to find volume around the y axis u need x^2, so x^2=c^2. Integrating this u get c^3 / 3 between o and h

    For the power of the belt i had P= Force times Velocity, my velocity was 0.877777 and force was mgsin(theatre) cant remember my final answer though, what was the dimensions and weight> 115kg?

    Haha yew ! solid effort mate, the macrostructure for the laminated i did laminated glass with two sheets of glass and a polymer film inbetween the two. The problem that alot of people had would've been differentiating between MACRO and MICROstructure. Im guessing i got around 82% ish... so im...

    The voltage of the cell is 18V, the lightbulb uses up 2V, therefore the final voltage is 16V, sub this into the equation and you get 0.02AMPS. Multiply this by 10^3 and you get 20mA. NOT 2.5 sorry

    Not necessarily, it said assume 100% efficiency, so MA = VR (MA / Vr = 1) i had some bullshit answer of like 6.25 iduno
