A barge floating in fresh water (Q = 1000 kg/m) is shaped like a hollow rectangular prism with base area A = 750 m2 and height H=2.0 m. When empty the bottom of the barge is located Ho=0.55 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H=1.05 m below the surface. Part (a) Select the correct free-body diagram for the barge when it is empty.Part (b) Write an equation for...

A dense plastic toy of mass 2.4 kg is floating just beneath the surface of a pond. What is the buoyant force on it? You lower a 2.8 kg solid gold statue into a container of water and measure the volume of displaced water. What volume will verify that it is pure gold if the density of gold is 19.3 g/cm3? A 4 meter-long hose of 7 cm diameter is con- nected to a faucet, and a 3 meter-long hose,...
If your body has a density of 985 kg/m^3, what fraction of you will be submerged when floating quietly in the following liquids? fresh water ____________ % the Great Salt Lake, which has a density of 1030 kg/m^3 ____________ %
A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density the same as that of the water. Suppose that with its air sacs collapsed, a fish has a density of 1.09 g/cm3. To what fraction of its expanded body volume must the fish inflate the air sacs to reduce its density to that of water?
