Q5.

The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy
