A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability.

A warship with a streamlined hull designed to operate completely submerged in the sea for long periods, equipped with a periscope and typically armed with torpedoes or missiles.

How submarine works?

A submarine (or any boat) can float when the mass of water that it displaces (pushes out of the way) is equal to the mass of the boat. This displaced water causes an upward force called buoyancy. Buoyancy acts in the opposite direction to gravity, which would pull the ship down.

A submarine is different from other ships, though, because it can control its buoyancy. This means the submarine captain can decide when to sink down into the ocean or come back up to the surface.

History of Submarine

The first practical submarine was built in 1620 by Cornelis Drebbel under the employ of King James I. A leather-covered 12-oar rowboat, Drebbel’s submarine was reinforced with iron to withstand water pressure, and was functional, submerged to a depth of fifteen feet beneath the River Thames. No further models were commissioned for the navy.

Use of Submarine

Civilian uses include marine science, salvage, exploration, and facility inspection and maintenance. Submarines can also be modified for specialized functions such as search-and-rescue missions and undersea cable repair. They are also used in tourism and undersea archaeology.

 Submarines have played a major role in any country’s navy.

Submarines are most prominent in navies; however, they are also used in other venues. In recent decades, they have become much more commonly used as a research tool as well. They allow scientists to travel deep into the see and study deep water sea life. Not long ago, the depths of the oceans were a mystery, no one had been deep enough to see what really existed beneath the surface. With submarines, however, researchers are allowed a safe way to study the deep sea, with out having to die doing so.

Submarines have also become more popular in tourism. Mostly in warm climates, these vessels will take tourists close to the ocean floor, in a dry, safe medium.

WHAT IS HONEY

 WHAT IS HONEY

Honey is a sweet, viscous food substance made by honey bees and some other bees. Bees produce honey from the sugary secretions of plants (floral nectar) or from secretions of other insects (such as honeydew), by regurgitation, enzymatic activity, and water evaporation. Honey bees store honey in wax structures called honeycombs, whereas stingless bees store honey in pots made of wax and resin.
