What is the difference between a normal ship and a submarine?
Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface. When normal ships go down, they stay down. Submarines are able to come back up after they go down. All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.
Why does the submarine float and submerge in water?
Submarines must be able to float to load and offload crew and cargo and to have repairs and maintenance. They are designed to submerge either for underwater exploration or to pass undetected by ships at the surface and planes and satellites above.
Why do ships float while submarines sink?
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
What is another word for going under something?
"Subduction" is what the earth does. Submarines "submerge".
How do submarines control their density?
By their pumps and ballast-tanks: allowing water into the tanks to raise the vessel's density so can submerge, or pumping air into the tanks to displace the water and allow the submarine to surface.
When water fills a submarines flotations tanks the overall density of the submarine?
The density will rise and submerge the submarine.
What is the opposite of submerge?
Dry, surface...
What is the reason why submarine submerge?
Submarines submerge primarily to avoid detection and protect themselves from threats, such as enemy ships and aircraft. By diving underwater, they can utilize the ocean's layers to mask their presence and minimize the risk of being targeted. Submerging also allows submarines to conduct stealthy operations, gather intelligence, and launch missiles while remaining concealed. Additionally, submerging enables them to operate in environments where surface navigation may be compromised.
Can submarines swim?
Submarines do not swim in the traditional sense like fish or marine mammals; instead, they navigate through the water using buoyancy and propulsion systems. They can submerge and surface by adjusting their buoyancy through the use of ballast tanks and control surfaces. While they are designed to move underwater, their operation is fundamentally different from swimming.
Problems with submarines?
All submarines can sink. Some can return to the surface.
What is the maening of submerge?
to sink below the surface of water
What is a ballast tank?
A ballast tank is one of several external or internal tanks fitted in submarines, which allow the boat to submerge when filled with water.
