6.20) Calculate the density of a fluid in which a hydrometer of uniform density 0.80g/cm^3 floats with 90% of its volume submerged. Note: Pls provide me an answer with relative solution/formula to this problem. Thanks!

6.21) Calculate the density of a person who floats in fresh water with 5.0% of her volume above the surface. Note: Provide solution/formula in the answer. Thanks!

7.1) The pressure in the esophagus is -10 mm Hg. Convert that pressure to centimeters of water, as it would be measured by a water manometer. Note. Provide me a solution with formula used. Thanks!

6.22 )An ornithologist weighs a bird bone in air and in water to find the bone's density. The mass of the bone in air is 25.0 g and its apparent mass in water is 2.0 g. a. What mass of water does the bone displace? b. Calculate the volume of water displac...

5.29) The formation of condensation on a cold glass of water will cause it to warm up faster that it would have otherwise. If 8.0 g of water condenses on a 100 g glass containing 300 g of water at 5.0°C, what will be the final temperature? Ignore the effe...

7.3) a. Calculate the pressure exerted on a disk in the lower back having an area of 20 cm^2 if a woman stands erect and supports the weight of her upper torso on that disk. The mass of the upper torso is 25 kg. Express this pressure in mm Hg. b. If this...

6.15) You wish to design a hydraulic system so that a force put into it would be increased by a factor of 100. a. What must be the ratio of the area of the slave cylinder to the area of the master cylinder? b. What must the ratio of thr diameter of the sl...

6.23) In a measurement of a man's density he is found to have a mass of 65.0 kg in air and an apparent mass of 1.50 kg when completely submerged in water with his lungs empty. a. What mass of water does he displace? b. What volume of water does he displac...

7.5) If the maximum force that an eardrum can withstand without breaking is 3.0 N and the area of the eardrum is 1.0 cm^2. A. Calculate the maximum tolerable pressure in the middle ear in N/m^2 and convert this to mm Hg. When might the pressure in the mid...

7.28) Confirm the values for the power output of the heart given in table 7.2 for an active person by starting with the values for a restong person and assuming a 50% increase in blood pressure and a factor of 4 increase in flow. Note that if flow increas...
