Question

A cubical block of wood, 10.2 cm on a side, floats at the interface between oil and water with its lower surface 1.60 cm below the interface (the figure (Figure 1) ). The density of the oil is 790 kg/m3.

A) What is the gauge pressure at the upper face of the block?

B) What is the gauge pressure at the lower face of the block?

C) What is the mass of the block?

D) What is the density of the block?

Answer #1

A block of wood floats partially submerged in water. Oil is
poured on top of the water until the block of wood is totally
submerged, partially in water and partially in oil as shown in the
figure. A clear cup is partially filled with water, and has oil
floating on top of the water, almost filling the vessel. Completely
submerged in the fluids is a block. The block floats so that part
of it is in the water and part...

A cube of side length 10.0 cm and made of unknown material
floats at the surface between water and oil. The oil has a density
of 810 kg/m3. If the cube floats so that it is 72% in
the water and 28% in the oil, what is the mass of the cube and what
is the buoyant force on the cube?

A wood cube 0.26 m on each side has a density of 730 kg/m3 and
floats levelly in water.
What is the distance from the top of the wood to the water
surface? 7.0 x 10^-2m
What mass has to be placed on top of the wood so that its top is
just at the water level?

A block of wood of mass 10.8 kg and density 4.42 x 10^2 kg/m3,
floats on water. (a) What is the minimum amount of aluminum
(density 2.70 x 10^3 kg/m3) that can be placed on top of the wood
block and cause the block of wood and the aluminum to sink? (b) If
instead it was a block of ice of mass 10.8 kg and density 8.90 x
10^2 kg/m3. What is the minimum amount of aluminum that can be...

A cube of wood with dimension 20 cm and density 650
kg/m3 floats in water.
a.)What is the distance from the top surface of the cube to the
surface of the water?
b.)How much mass of lead is required to be put on cube so that
the top of the cube is level with the surface of the water?

A wood cube 0.28m on each side has a density of 680kg/m3 and
floats levelly in water.
What is the distance from the top of the wood to the water
surface? (in m)

A block of wood
(density 713 kg/m3)
of length L = 50.0 cm, width W = 40.0 cm, and thickness
H
=
30.0 cm floats in water (density
1.000 × 103
kg/m3).
What is the
volume percentage of the wood that is above water?
If the wood is
set to oscillate, what is its frequency?
How much can the
wood carry without sinking?

A 10cm×10cm×10cm wood block with a density of 730 kg/m3 floats
in water.
What is the distance from the top of the block to the water if
the water is fresh?
If it's seawater? Suppose that ρ=1030kg/m3.

A 10cm×10cm×10cm wood block with a density of 730 kg/m3 floats
in water.
a: What is the distance from the top of the block to the water
if the water is fresh?
b: If it's seawater? Suppose that ρ=1030kg/m3.

A rectangular block of ice 13 m on each side and 1.1 m thick
floats in sea water. The density of the sea water is 1025
kg/m3. The density of ice is 917 kg/m3.
1)
How high does the top of the ice block float above the water
level?
2) How many penguins of mass 20 kg each can stand on the ice
block before they get their feet wet?
