in the water
Pink dolphins are like submarines because they never go in the water, dolphins and submarines alike are have waterphobia and never go in the water. Pink dolphines also are lesbians like submarines
As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
Submarines are built with a special design that allows them to be faster underwater. Submarines can be used during a war as a way to sneak up to enemy lines in the water, but still stay hidden.
Submarines can operate under water, but not under land. The US is a nation on land, and submarines cannot operate under it.
because they have to withstand the pressure of the water when they go down under water. and to keep the people safe :)
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
Yes definitely. Maybe not military class submarines but there are many public submarine tours that take you under the water to see shipwrecks, sea life etc
Fish comes top of the water to get oxygen.
As with all boats, a submarine does not weigh as much as the amount of water it displaces. To go under the water's surface, it pumps water into special tanks (ballast tanks), and to rise up again those pumps force the water out of the ballast tanks and back into the sea.Ans 2 - Submarines can go deep and rise again by using water ballast and air pressure, as planned by the captain. -Unfortunately, when things go wrong, submarines DO sink.
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.
