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
military submarines use low frequency antenna that extends from the sail(conning tower.) The message is typed into a computer, then is sent to another submarines antenna that receives it and displays it on a computer.
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.
USA. nuclear powered submarines can go faster than 25 knots (nautical miles per hour) underwater.
submarines are important because people need to go under the sea and do what they got to do to save the world
Submarines help scientists by going to the lowest possible depths of the ocean. Humans aren't built for that, as we cannot stand the intense pressure due to the depth. Submarines can go as low as they need AND sustain human inside them. They are wonderful and very helpful. Submarines are helpful to Scientist so they can explore the great depths of the oceans, seas etc. It helps them find out how the sea creatures live under water and what types of sea creatures live underwater. It also helps them to where they can learn about new species of sea creatures. So that is why submarines are so helpful to scientist
No of course not
Radio waves as low as 10kHz are used for communication with submarines.
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.
