a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury? The density of wateris 1.0 g/mL, whereas that of mercury is 13.6 g/mL.
b) What is the pressure in atmospheres on the body of a diver if heis 39 ft below the surface of the water when atmospheric pressureat the surface is 0.97 atm?
