The frequency f of a wave is defined as the inverse of the period T:

The clock in the problem has a waveform with period

. Therefore, its frequency is
Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.
Hope this helps (:
