Unformatted text preview: 14.23: a) The displaced fluid must weigh more than the object, so < fluid . b) If the ship does not leak, much of the water will be displaced by air or cargo, and the average density of the floating ship is less than that of water. c) Let the portion submerged have V volume V, and the total volume be V0 . Then, Vo = fluid V , so V0 = fluid The fraction P above the fluid is then 1 - Pfluid . If p 0, the entire object floats, and if fluid , none of the object is above the surface. d) Using the result of part (c), 1- fluid (0.042 kg) (5.0 4.0 3.0 10 -6 m 3 ) = 1- = 0.32 = 32%. 1030 kg m 3 ...
