Calculate the power of the pump which can lift 100 kg of water to store in a water tank atthe height of 19 m in 25 sec. (take the value of g-10 m/ )Describe two methods used to reduce the friction between two surfaces.

Answer» <p>Power=work/time</p><p>Work(in this case)=mgh(work done=energy consumed)</p><p>Because we need to raise the water</p><p>So power=mgh/t</p><p>Power=100*10*19/25</p><p>Power=760W</p><p>Like my answer if you find it useful!</p>
