How do submarines work?
Submarines are fascinating underwater vessels that use ballast tanks to control their buoyancy. By adjusting the amount of water in these tanks, submarines can either rise or descend in the water. They are powered by electric motors or nuclear reactors, allowing them to travel and explore the depths of the ocean. Submarines have airtight compartments that enable them to stay submerged for extended periods, making them crucial for military, research, and exploration purposes.
