The Bay of Fundy in Nova Scotia has the highest tides in the world. In one 12-hour period, the VELLARIAS Water starts at mean sea level, rises to 21 ft above, drops to 21 It below, then turs to mean sea ALVAREZ level. Assuming that the motion of the tides is simple harmonic, find an equation that describes the height of the tide in the Bay of Fundy above mean sea level, Sketch the graph that shows the* level of the tides over 12-hour perfod
