Solution

The correct option is D c,b,d,a,e
Initially water is collected in the dam. When it is released, the potential energy is converted to kinetic energy. The released water is made to fall on the blades of turbines. The armature of the electric generator rotates to produce electricity.

Hence, the correct order is c,b,d,a,e. Hence, option (D) is correct.

Q. The height of water in a dam reduces by

20 m

, which is used to generate electricity. The water further fell by

10 m

into the tunnel to strike the turbine plates. If the volume of water is

10^{4} m^{3}

, find the hydel energy generated. Assume all the potential energy of the water being converted into electricity. Take

g = 10 m s^{- 2}
