Question

For a submarine to stay submerged, it must be neutrally buoyant, which means it is maintaining a careful balance between its weight and the buoyant force of water pushing it toward the surface. If a submarine has an enclosed volume of 327.781 m3, how much must it weigh to stay submerged? (Use 1000 kg/m^3 for the density of water.)

Answer #1

Weight of submarine can be find using below formula

Weight of submarine=buoyant force=

A toy submarine of mass 12.2 kg is fully submerged in a pond but
not floating or sinking.
A. What is the volume of the submarine?
B. What is the buoyant force on the submarine?
C. If it is 3.8 m below the surface, what is the total
(absolute) pressure acting on it?

1.)The Buoyant Force from a fluid to an object depends on which
of the following factors?
a.)The volume of the object
b.)The volume of the fluid
c.)The density of the fluid
d.)The density of the object
2.)Why did the Titanic sink after it hit an iceberg and water
rushed into the hull through the hole created by the
collision?
a.)The density of water has increased
b.)The density of the boat increased
c.)The mass of the boat has decreased
d.)The volume...

A spherical ball with a radius of 2.800×10-1 m is
completely submerged in a fluid that has a density of
1.134×103 kg/m3.
What is the volume of the fluid displaced by the ball? (Since the
ball is completely submerged, this is the same as the volume of the
ball.)
What is the weight of the fluid displaced by the ball?
What is the buoyant force acting on the ball? (See Archimede's
Principle in the text.)

4:A submarine descends into the sea to a depth of 200 m below
the surface of water.
The density of the sea water is 1.03 g/cm3. Atmospheric
pressure is 1.0 x105 Pa.[10 marks]
Calculate:
(a) The increase in pressure as it descends from the surface
to a depth of 70 m.
(b) On another dive, the submarine experiences a total
pressure of 6.5 x105 Pa.
A hatch cover on the submarine has an area of 3.5 m2.
Calculate the force...

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 sea lion (with lungs empty) is put on a scale when it is
completely submerged in water. The scale reads the “apparent weight
force” of the sea lion in water as 62.01-N. The sea lion has a mass
of 210.0-kg. The density of water is 1000 kg/m3.
Determine the density of the sea lion.
Select one:
a. 1000 kg/m3
b. 419 kg/m3
c. 1029 kg/m3
d. 1419 kg/m3

A trapezoidal plate, with 9m and 5m bases and 3m height, is
submerged vertically in a tank of water so that its top is 2m to
the water surface (as figure below). Calculate the hydrostatic
force against one side of the plate. (Water mass density ρ = 1000
kg/m3, and g = 9.8 m/s2).
Please help me with this. My answer is 690900.

Find the Buoyant Force on a person with 85% of his body under
the water, the density of fresh water is 1000 kg/m^3 (1.0 g/cm^3),
the mass of the person is 60 kg and the density of the human body
is 985 kg/m^3 (0.85 g/cm^3). Volume of the person =mass / average
density of human body

A lost shipping container is found resting on the ocean floor
and completely submerged. The container is 6.3 m long, 2.8 m wide,
and 2.1 m high. Salvage experts attach a spherical balloon to the
top of the container and inflate it with air pumped down from the
surface. When the balloon's radius is 1.2 m, the shipping container
just begins to rise towards the surface. What is the mass of the
container? Ignore the mass of the balloon and...

piece of cork is held partially submerged in water by a string
attached to its bottom. The weight of the
cork in air is 20.0 N. The tension in the string is 10.0 N.
(a) What is the buoyant force on the cork? (Newston's 1st
law)
(b) What is the volume of the cork under water? (Archimedes
Principle)
(c) If this volume is 20.0% of the total volume of the cork,
what is the density of the cork?
Oil of...
