A rectangular parallelepiped with a square base d = 0.255 m on a side and a height h = 0.120 m has a mass m = 6.10 kg. While this object is floating in water, oil with a mass density Po = 710 kg/m3 is carefully poured on top of the water until the situation looks like that shown in the figure. Determine the height of the parallelepiped in the water. m oil hw water Using data from the diagram below, calculate the ratio of the height to which water at 20C and mercury are raised or suppressed by capillary action in the same glass tube. (Use density and surface tension values of water that are accurate to at least 3 significant figures for your calculation. Include the appropriate sign with your answer.) hw hm 2r F Ow = 0 hw hm - 2r Om= 140 water mercury
