help A piece of wood floats in water. It measures 49 cm x 12 cm x 11 cm, and has a density of 500 kg/m3. Find the percent of the wood that's underwater, if the density of water is 1000 kg/m3 Hint: Answer should be between 0 and 100 % Buoyancy problem: draw the wood and the forces on it - namely gravity pulling down and the buoyant force of the water pushing up ∑F = 0 the buoyant force = Fb = density of fluid x g x Volume underwater = density of fluid x g x percent * total volume solve for percent
P Which of the following statements accurately describes the buoyant force? The buoyant force is the force exerted on an object submerged in a fluid that causes it to sink. The buoyant force is the force exerted on an object submerged in a fluid that opposes its motion. The buoyant force is the upward force a fluid exerts on an object. The buoyant force is the force exerted on an object submerged in a fluid that is equal to the weight of the object. 4 UNANSWERED 5:47 15:57 QUESTION 1/4 ㄒㄧ→ Clemson Univers
