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.

What objects will float sink then float?
A submarine
How does a submarine relate to astronomy?
the ability of the submarine to float
How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
Why does a submarine can sink and float in water?
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
Will a submarine sink or float when it's weight is equal to the upthrust acting on it?
If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.
Will the submarine sink or float when its weight is equal to the upthrust acting on it?
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
Does a submarine sink or float?
both. they are able to control it
The density of a submerged submarine is about the same as the density of?
The density of a submerged submarine is about the same as the density of the fluid it is submerged in, which is typically seawater. This allows the submarine to float or sink based on its buoyancy and weight.
How do you make a plastic bottle submarine float then sink and float?
put water in to let it sink... then put air into it to let it float...
How do submarines float and sink in water?
a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water. use the formula density= mass / volume as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
What can go across the Atlantic oceon?
anything that can float on water, unless its a submarine
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.
