because its a boat, without buoyancy it would sink

What are the purpose of ballast tanks?
to control the buoyancy of a submarine
Is the buoyancy of the Dead Sea because of the hyper salinity and is buoyancy experienced in lake Asal?
Salt does make a difference in buoyancy but if there is no salt then you shouldn't sink to the bottom. Your head will go under. Every object has some degree of buoyancy in water. Some have enough so that they float, others do not. _______ Actually, the Dead Sea is not 'buoyant'. Buoyancy is a property of a solid object you put in the water. The salinity of the dead sea increases the specific gravity of its water. Specific gravity is to liquids as density is to solids. So the water of the Dead Sea has a very high specific gravity.
Is the submarine cable is suitable for under water?
Submarine cables are only suitable for use under water, that is what they are made for.
How is a submarine canyon formed?
A submarine canyon refers to a steep-sided valley cut into the sea floor of the continental slope. It is formed through turbidity currents that carve out the submarine canyons in the continental shelf.
What is the physics in swimming?
For every action there is an equal but opposite reaction. All of newtons laws aply as well as achemedes principle
What has buoyancy?
a submarine
What has neutral buoyancy?
a submarine
What is a submarines buoyancy?
A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
How does a submarine float?
It floats and sink by changing its buoyancy. The primary method of controling buoyancy is the ballast tanks. The air is let out of them and is displaced by water. This gives the submarine negative buoyancy, which will get the submarine to submerge. By blowing or pumping air into those ballast tanks, the submarine becomes buoyant and rises to the surface.

The buoyancy force on a submarine submerged in the ocean equals what?
the weight of the water displaced by the submarine.
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
What are the purpose of ballast tanks?
to control the buoyancy of a submarine
What kind of buoyancy did the first submarine?
almost neutral

What is the function of the ballast tanks on a submarine?
To change the buoyancy of the boat and allow it to rise and sink in the water.
