The very first submarine, known as the "Nautilus," was designed by David Bushnell in 1775. Its buoyancy was primarily controlled by allowing water to fill a ballast tank, which would displace air and cause the vessel to sink. When it needed to surface, the water would be expelled, allowing the submarine to rise. The design was rudimentary compared to modern submarines, but it laid the groundwork for future underwater vessels.

What kind of buoyancy did the first submarine?

What kind of buoyancy did the first submarine have?
almost neutral

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 buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
How does change in buoyancy affect the function of a submarine?
A change in buoyancy affects a submarine's ability to rise and sink in the water. By adjusting the amount of water in its ballast tanks, the submarine can control its buoyancy and depth in the water. This is essential for navigating through different depths and maintaining stability.
What are the purpose of ballast tanks?
to control the buoyancy of a 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.
The buoyancy force on a submarine submerged in the ocean equals?
the weight of the ocean water displaced by the submarine.
