Submarines can pump sea water into or out of ballast tanks, if they wish to change their weight (of course, anything that enters or leaves a submarine will also change its weight - people, supplies, weapons, etc. - but if you just want to change the weight, the easiest way is to pump water into the submarine).
What else can I help you with?

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.
How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
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.
When a submarine pumps water out of its inflation tanks its density decreases and floats.why does its density decrease?
It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.
What is the Kursk submarine weight?
25,000 tonnes
The buoyancy force on a submarine submerged in the ocean equals?
the weight of the ocean water displaced by the submarine.
How does a submarine change its depth in the water?
A submarine changes its depth by adjusting its buoyancy through the use of ballast tanks. When it wants to dive, it takes in water into these tanks, increasing its weight and causing it to sink. To ascend, the submarine expels water from the ballast tanks, typically by using compressed air, which reduces its weight and allows it to rise. This ability to control buoyancy enables submarines to maneuver effectively underwater.
When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
What is the apparent weight of a submarine that weighs 1256N and it displaces 1562N of water?
The apparent weight of the submarine is calculated by subtracting the weight of the water it displaces from its actual weight. In this case, the apparent weight of the submarine would be 1256N - 1562N = -306N. This negative value indicates that the submarine will feel lighter when submerged in water due to the buoyant force acting on it.
What is a w and d on a submarine?
My guess would be Weight and Draft
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.
