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.

What is the purpose of a submarine ballast tasks?
They help the sub go up and down. When water is allowed into the tanks, the sub goes down. When water is pushed out of the tanks, sub comes up.
What will float then sink then float?
[I've heard this question asked as a kind of a twisted riddle, the answer to which is, "A drowning person": When a person is first in the water, they have air in their lungs and will float. As they drown, their lungs fill with water and they sink. Then, as their body decays and gases expand, the body floats to the surface -- LibertarianLaw]A submarine or a ship can float because the weight ofwater that it displaces is equal to the weight of the ship. 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.To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below). When the submarine is on the surface, the ballast tanks are filled with air and the submarine's overall density is less than that of the surrounding water. As the submarine dives, the ballast tanks are flooded with water and the air in the ballast tanks is vented from the submarine until its overall density is greater than the surrounding water and the submarine begins to sink (negative buoyancy). A supply of compressed air is maintained aboard the submarine in air flasks for life support and for use with the ballast tanks. In addition, the submarine has movable sets of short "wings" called hydroplanes on the stern (back) that help to control the angle of the dive. The hydroplanes are angled so that water moves over the stern, which forces the stern upward; therefore, the submarine is angled downward.
Where is the ignition ballast resistor on a 1988 dodge Dakota 3.9?
A 1998 Dakota does not have a ballast resistor.
To halt its descent a diving submarine might?
To halt its descent, a diving submarine might adjust its buoyancy by taking on water into its ballast tanks or expelling water to become more buoyant. It could also increase its speed by using its propellers to generate lift, or angle its bow upward to reduce downward momentum. Additionally, activating the submarine's control surfaces, such as the stern and bow planes, can help manage its depth and stabilize its ascent.
How can a submarine control its sinking and floating?
If the question refers to the submarine's ability to maintain a certain depth, the answer is probably that the trim and the planes are employed to hold at a given depth. It might help to recall that a submarine is set up to be neutrally buoyant while underwater. By the use of trim to keep the submarine running level in the water with the planes at a zero angle, the planes can themselves be nudged a bit to push the submarine a bit more or less deep in the water.
What do fins do for a submarine?
The fins help steer the submarine; making it be able to turn left or right.
How does buoyancy and density help a submarine to dive and float?
A submarine has buoyancy tanks along its length. To dive or sink these are filled with water, which enters through valves, so the vessel becomes heavier. Its speed of descent can be controlled by the amount of water in the tanks and also by aerilons (small wings) which can be tilted to steepen the dive. There is obviously a depth limit for each submarine. To surface the vessel blows the water out with compressed air, the vessel gets lighter (more buoyant) and rises to the surface.

What is the wood in the bottom of a ship to keep cargo dry?
The wood in the bottom of a ship to keep cargo dry is typically referred to as "ballast." Ballast is used to provide stability to the ship by adjusting its weight distribution. In some cases, ballast can also help prevent the cargo from shifting during rough seas. Additionally, ballast can help regulate the ship's draft and buoyancy to ensure safe navigation.
