(a) calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 28.6 m. assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kpa. (b) what force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 30.0 cm?
