The solid wood cylinder madder of oak with a uniform density of 750 kg/m³ is dropped in the ocean,which has a density 1027 kg/m³.The diameter of the cylinder is 0.540 m and its height is 0.240 m.Assuming that the flat ends of the cylinder are parallel to the surface of the water and that the water is calm,the top of the cylinder will A)be 0.175 m above the water line. B)be 0.123 m above the water line. C)be 0.0647 m above the water line. D)be 0.175 m below the water line. E)sink to the ocean floor.

Quizplus · Accepted Answer

The buoyant force equals the weight of the displaced water. The volume of the cylinder is π(0.270)^2(0.240) m³. The submerged volume is (density of cylinder/density of water) * total volume. The height above water is total height minus submerged height.
