Question

A uniform cube made of a material with density = 750.0
kg/m^{3} is placed in a pool filled with water. The
dimensions of the cube are 1.2x1.2x1.2 m^{3}. What fraction
of the volume of the cube will be submerged (density of water =
1000 kg/m^{3})

A raft is constructed of wood having a density of
6.00x102 kg/m3. Its surface area is 5.70
m2 and its volume is 0.80 m3. When the raft
is placed in fresh water, to what depth h is the raft submerged by
its weight? The density of fresh water is 1000
kg/m3.
Hint: Use Newton’s second to sum the forces (Buoyancy and
weight) that are in equilibrium.

A block of wood has a density of 700 kg/m3 . It is placed in a
fluid in which it floats with two-thirds of its volume submerged.
What is the density of the fluid? Express your answer in kilograms
per meter cubed.

If your body has an average density of 989 kg/m3, what fraction
of you will be submerged when floating gently in fresh water? What
fraction of you will be submerged when floating gently in salt
water, which has a density of 1027 kg/m3?

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 block of material with a density of 868 kg/m3 is floating in a
fluid that has a density of 1040 kg/m3. What fraction of the object
is above the surface of the fluid?

A 15-kg metallic cube with uniform density is immersed to a
depth of 2.0 m in a lake. If a buoyant force of 49 N acts
on the cube, what is the density (in kg/m3) of the metal?
Answer: 3000

A uniform, wooden cube with length d = 3.0 cm on each
side has a density r = 500 kg/m3 and floats
motionlessly in water (density 1000 kg/m3). (Take the
acceleration due to gravity to be 9.8 m/s2.) When
pressed down by a small amount, and released, what is the
approximate frequency of the resulting up-and-down
oscillations?

A block of wood has a mass of 3.67 kg and a density of 594 kg/m3
. Attached below the wood is a mass of lead. If the wood is to
float in water with 0.883 of its volume submerged, what mass of
lead will be needed? (Density of lead is 11.3x103 kg/m3 )

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?

The density of an object is about 400 kg/m3, and the density of
water is about 1000 kg/m3. A cubic block of the object one meter on
a side floats in water. Assuming that the lowest square face of the
cube is horizontal, the height of the block above the water line
is
0.9 m.
0.8 m.
0.5 m.
0.6 m.
0.1 m.
