    As physics p1 MCQS YEARLY ONLY.

    for Q no. 19 you need to find the power input... power = work done / time work done = F x D or rather F here as Weight =mg = to find mass you use the formula density = mass/volume= 1000 x 340 = 340000... now converting it to weight x 9.8 = 3332000 ... Work done = 3332000 x distance (30 ) =...

    1200- T = 120 x a --- first eqaution T-800=80 x a --- second equation.... substracting them from each other you get 400 = 200 a ... a = 2 v^2= u^2 + 2as = (2 x 2 x 9 )^1/2 = 6

    The voltmeter has a very high resistanc and so there will be no current through it for any position of the slider. So, there will be no potential difference across P and the voltmeter will always just record the p.d acrosss Q

    q 3 -- at the maximum height the horizontal component is 0 and the only component acting is the vertical one which when you resolve gives you vsin(x) (this is the final velocity) now considering the equation v^2=u^2+2gs you substitute and rearrange ... q -5 you add up all the PERCENTAGE...
