Chapter 10 Homework
1. (p.304 prob.5) A bottle has a mass of 35.00g when empty and 98.44g when filled with water. When filled with another fluid, the mass is 88.78g. What is the specific gravity of this other fluid?
2. (p.304 prob.11) The gauge pressure in each of the four tires of an automobile is 240kpa. If each tire has a "footprint" of 200cm2, estimate the mass of the car.
3. (p.p.304 prob.14) What is the total force and the absolute pressure on the bottom of a swimming pool 22.0m by 12.0m whose uniform depth is 2.0m? What will be the pressure against the side of the pool near the bottom?
4.(p.305 prob.18) Determine the minimum, gauge pressure needed in the water pipe leading into a building if water is to come out of a faucet on the twelfth floor, 41m above.
5. (p.305 prob.29) A 0.48-kg piece of wood floats in water but is found to sink in alcohol (specific gravity = 0.79) in which it has an apparent mass of 0.035kg. What is the SG of the wood?
