The average human body has a density of 1,020 kg/m³, while mercury has a density of 13,600 kg/m³. Consider a 87.5 kg man floating in a bath of mercury, as shown below. (a) What percentage of the volume of the man's body is submerged beneath the surface of the mercury? (b) What downward force would would you need to apply to the man to completely submerge him in the mercury? Give your answer in units of Newtons.
