    18)Efficiency is given by (Useful Output Work)/(Total Input Energy) = (Useful Output Work per Second)/(Total Input Energy per Second) The useful output work per second = useful power output = 150 * 10^3 Joules Per Second. Therefore, Efficiency = (150 * 10^3 Joules/Second)/(Total Input Energy...

    I am busy... but here is ur 17 :¬ F=α*V2 so α=F÷(v2) α=800÷20=2kg.m−1 P=W÷t=(F*d)÷t=F*v F=(2kg.m−1)×(40m.s−1)2=3200N and finally P=40m.s−1*3200=128000Watts=128KW and above post has explained 30 even.. I'll solve 18 35 and 36 in few mins
