consider a basin with a rectangular base, 1000feet inland and 500feet across. let the y-axis be at the shoreline and the x-axis represent the low tide. the basin has a tidal range of 25feet, with the low tide corresonding to y=0. a) how much water does the basin hold at high tide? b)the amount of energy produced during the filling of the basin is proportional to the amount of work required to fill the basin. how much work is required to fill the basin with seawater? (seawater has a density of 64 pounds per cubic foot
