An ice cube floats in a beaker of ice cold water. Since the water is ice cold, the ice cube is not melting and hence its volume is not changing. The density of water and ice are, respectively, ρw = 1,000 kg/m3 and ρi = 917 kg/m3. (Assume one of the ice cube's faces is parallel to the water's surface.) (a) If the ice cube is 17.0 mm on each side, how far below the surface (in mm) is the...
