What is the density (in kg/m3) of a woman who floats in freshwater with 4.32% of her volume above the surface? (This could be measured by placing her in a tank with marks on the side to measure how much water she displaces when floating and when held under water.) (Give your answer to at least three significant figures.) What percent of her volume is above the surface when she floats in seawater?

Breathing in deeply changes the volume of your body. At a spa, a woman stands on a scale completely submerged in a liquid of specific gravity 0.973. The scale reads 20.4 N with her lungs full of air, and 54.6 N with her lungs empty. Assume the weight of the air in her lungs is negligible compared to her body weight. Find the volume of air she inhales, in cm3.

A block of wood floats partially submerged in water. Oil is poured on top of the water until the block of wood is totally submerged, partially in water and partially in oil as shown in the figure. A clear cup is partially filled with water, and has oil floating on top of the water, almost filling the vessel. Completely submerged in the fluids is a block. The block floats so that part of it is in the water and part...

A sea lion (with lungs empty) is put on a scale when it is completely submerged in water. The scale reads the “apparent weight force” of the sea lion in water as 62.01-N. The sea lion has a mass of 210.0-kg. The density of water is 1000 kg/m3. Determine the density of the sea lion. Select one: a. 1000 kg/m3 b. 419 kg/m3 c. 1029 kg/m3 d. 1419 kg/m3
