1) What mass (in kg) of iron must be placed on top of the wood block so that the wood block is just barely submerged (the top of the block of wood is level with the surface of the water and the iron on top is in the air). The volume of the wood block is 0.00782 m^3. The density of the wood is 620 kg/m3 and the density of the water is 1000 kg/m3. 2) Most cars have hydraulic...

) The back of a frog has a surface area of 0.0052 m2. If the frog is on land at sea level, how much force will the frog’s back feel from air? The frog swims to a depth of 0.45 m in freshwater. What is the total pressure (from air + water) that the frog will feel on its back at that depth? If the frog instead was swimming in saltwater, which has a density of 1025 kg/m3, what depth...
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
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 U-tube contains liquid of unknown density. An oil of density
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.
