Question

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.

Answer #1

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 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 10cm×10cm×10cm wood block with a density of 750 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.
Express your answer to two significant figures and include the
appropriate units.

A block of wood has a mass of 3.57 kg and a density of 588
kg/m3. It is to be loaded with lead so that it will
float in water with 0.82 of its volume immersed. The density of
lead is 1.13 ? 104 kg/m3.
(a) What mass of lead is needed if the lead is on top of the
wood?
(b) What mass of lead is needed if the lead is attached below the
wood?

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 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)
Express your answer using two significant figures
What mass has to be placed on top of the wood so that its top is
just at the water level? (kg)
Express your answer using two significant figures.

A block of wood has a mass of 3.81 kg and a density of 535
kg/m3. It is to be loaded with lead (1.13 ×
104 kg/m3) so that it will float in water
with 0.838 of its volume submerged. What mass of lead is needed if
the lead is attached to (a) the top of the wood
and (b) the bottom of the wood?
(a)

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 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.
