(a) Calculate the absolute pressure at the bottom of a freshwater lake at a point whose depth is 25.5 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 32.4 cm?
