Question

How sumberens are floating and change it’s direction

Answer 1

Explanation:

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 wate

Answer 2

With water inside the tanks, the sub has negative buoyancy so it sinks deeper into the ocean. The tanks at the front (known as the front trim tanks) are usually filled with water or air first, so the submarine's front (bow) falls or rises before its rear (stern).
