There wasn't anything it could do. It was a British ship torpedoed by a German submarine and those two countries were at war.


How does a submarine works that floats then sinks and then again floats?

A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.

What do British people call sinks?

They call them sinks.


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.


If a submarine starts to sinks will it go to the bottom if no changes are made?

If a submarine takes on enough water, like any vessel, it'll sink straight to the bottom without intervention.


What does a submarine alter to rise and fall in water?

A submarine alters its buoyancy to rise and fall in water by adjusting the amount of water in its ballast tanks. When the tanks are filled with water, the submarine becomes heavier and sinks; when air is pumped into the tanks, the submarine becomes lighter and rises. This process allows the submarine to control its depth in the water column effectively.


How does neutral buoyancy work?

It is when the object neither sinks nor conpleatly floats on top of the surface it stays in the middle kind of what a submarine does


Why might a submarine be crushed if it sinks too low in the ocean?

Submarine hulls are subject to sea pressure, and that pressure increases the deeper the submarine goes. There are design limits to the amount of pressure that a hull can take, and if that pressure is exceeded by diving too deep, the hull will fail and will be crushed.


How would a submarine fall from the surface of water to the seabed and back up to the surface of water?

Fill it with water; it sinks. Fill it with air, it rises.


Why do submarines submerge?

To control its buoyancy, the submarine has ballast tanksand auxiliary, or trim tanks, that can be alternately filled with water or air. When you fill it with water, it sinks, When you first let the water out then you let the air in (from compressed air in the submarine) it floats.


How does a submarine change its buoynacy so it can float or sink?

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.
