Q5.
<span>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.

Q6
<span>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</span>
