Figure is a representation of the effects of the tide on a small body of water connected to the ocean by a channel. Assume that the ocean height h, varies sinusoidally with a period of 12 hr with an amplitude of 3 ft about a mean height of 10 ft. If the observed amplitude of variation of h is 2 ft, determine the time constant of the system and the time lag between a peak in hi and a peak in .
