Question # 1

Explain how a submarine moves up the waters surface and down into water

Ans 1: Submarine can also travel over and under water, when weight of water equal to its volume is greater than its weight. Submarine has a system of tanks. When tanks are filled of sea water, weight of submarine increases, As soon as weight of submarine become greater than upthrust of water, it dives into water and remains under water
