because the submarine has the water tank.when the tank is filled then submarine sink in the water.and when the tank is empty then submarine float in water.
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.
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.
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.
A submarine has "ballast tanks" which can be filled with water to make the vessel heavier (total density greater) than water and dive to required depth. These ballast tanks can also be filled with air (compressed air is kept on board for this) to make the vessel lighter and rise to the surface
A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.
put water in to let it sink... then put air into it to let it float...
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.

both. they are able to control it

It takes on water to alter its density to greater than that of water, allowing it to sink, pumping the water out reverses the state, allowing it to rise.

This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.
it will float as long as it is not fully covered water.
Arsenic is denser than water, so it will sink in pure water.
