Question

calculat the power of an electric motor that can lift 1000kg of water to store in a tank at a height of 3000cm in 20sec (use g- 10m/s)​

Answer 1

Answer:

15000 Watt

Explanation:

height = 3000cm

            30m

potential energy = mgh

                            = 1000 x 10 x 30

                            = 300000 i.e. ( 3 x 10⁵ )

work done = energy

power = work done / time taken

           = 300000/20

           = 15000 Watt
