Activity Sheet on Buoyancy
Read Chapter 10, Sections 7-9 of Giancoli
on Giancoli 3rd Edition: pp. 269-270 #3, 4, 9, 16, 20, 21, 24, 27
3. (II) A bottle has a mass of 31.20 g when empty and 98.44 g when filled with water. When filled with another fluid, the mass is 88.78 g. What is the SG of the fluid?
4. (II) If 5.0 L of antifreeze solution (SG = 0.80) is added to 4.0 L of water to make a 9.0-L mixture, what is the SG of the mixture?
9. (II) What is the total force and the absolute pressure on the bottom of a swimming pool 8.0 m by 12.0 m whose uniform depth is 2.0 m? What will be the pressure against theย sideย of the pool near the bottom?
16. (II) 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 30 m above.
20. (I) A geologist finds a moon rock whose mass is 7.20 kg has an apparent mass of 5.88 kg when submerged in water. What is the density of the rock?
21. (I) What fraction of a piece of aluminum will be submerged when it floats in mercury?
24. (II) A 0.40-kg piece of wood floats in water but is found to sink in alcohol (SG = 0.79) in which it has an apparent mass of 0.020 kg. What is the SG of the wood?
27. (II) The specific gravity of ice is 0.917, whereas that for seawater is 1.025. What fraction of an iceberg is above the surface of the water?
