What is the sequence of energy conversions takes place in hydro power plants?
Energy can exist in several forms and may change from one form to another.For each of the following,state the energy changes that occur in:
(a) the unwinding of a watch spring,
(b) a loaded truck when started and set in motion,
(c) a car going uphill,
(d) photosynthesis in green leaves,
(e) charging of a battery,
(f) respiration,
(g) burning of a match stick.
(h) explosion of crackers.
Describe the energy changes which take place in a radio.
Electricity generated by water stored in hydro power plant is an inderect source of solar energy. Justify the statemnent by discussing in sequence the series of energy transformation taking place.
