In a total-immersion measurement of a woman’s density, she is found to have a mass of 63.5 kg in air and an apparent mass of 0.0875 kg when completely submerged with lungs almost totally empty. a. What mass, in kilograms, of water does she displace?  b. What is her volume, in cubic meters?  c.  Calculate her average density, in kilograms per cubic meter.  d.  If her lung capacity is 1.75 L, is she able to float without treading water with her lungs filled with air? Assume the density of air is 1.29 kg/m3.

A balloon filled with helium gas has an average density of ρb = 0.39 kg/m3. The density of the air is ρa = 1.23 kg/m3. The volume of the balloon is Vb = 0.045 m3. The balloon floats upward with acceleration a. a.) Express the acceleration of the balloon a in terms of the variables given in the problem statement, assuming upwards is the positive direction.  b.) Calculate the numerical value of a in m/s2.

A very simple way of measuring the depth of a fluid in a gas station's underground gasoline tank is by using a pressure gauge that measures gauge pressure. Assume the fluid in the tank is gasoline with a density of 700 kg/m3 and g = 9.80 m/s2. If the gauge pressure is 25.9 kPa what is the depth of the gasoline in the tank? Assume 3 significant digits. Watch the units!   A. 3.78 cm   B. 37.8 m   C. 0.378 m   D. 3.78 m   E. 3.78 mm

A cylindrical storage tank has a radius of 1.06 m. When filled to a height of 3.67 m, it holds 12600 kg of a liquid industrial solvent. What is the density of the solvent? Number i Units

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 6.22 × 10³ kg/m³. What fraction of the specimen's apparent volume is solid? Number i Units
