A barge floating in fresh water (p=1000 kg/m3) is shaped like a hollow rectangular prism with base area A=450 m2 and height H=2.0 m. When empty the bottom of the barge is located H0=0.55 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H1 = 1.4 m below the surfacePart (a) Find the mass of the coal in kilograms. Part (b) How far would the barge be submerged (in meters) if...

A board that is 20.0 cm wide, 5.00 cm thick, and 3.00 m long has a density 379 kg/m3. The board is floating partially submerged in water of density 1000 kg/m3. What fraction of the volume of the board is above the surface of the water? 0.379 0.200 zero 0.621 The answer depends on which edge of the board is vertical. A 3.1-kg solid sphere, made of metal whose density is 2500 kg/m3, is suspended by a cord. When the...

770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
