The gravitational force exerted by an object is given by F = mg where F is the force in newtons, m is the mass in kilograms, and g is the acceleration due to gravity, 9.81 m/ s2. Calculate the force exerted per unit of area by a column of mercury (density = 13.59 g/ cm3) that is 76.0 cm high. How high would a column of water (density = 1.00 g/ cm3) have to be to exert the same force?
