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
It depends on the submarine type and hull design. Older WWI and WWII Fleet submarines were specifically designed as surface ships with limited submergence capability - they primarily ran on the surface with their diesel engines, and submerged using their battery powered electric motors when attacking a surface vessel. This hull design made gave them a lower water resistance on the surface, but much higher underwater. Their speed underwater was almost half of what they could do on the surface. With modern submarines, the opposite is true. Submarines today are specifically designed for lower water resistance (higher speeds) underwater than they are on the surface. Top speed for most boats on the surface might approach 20 knots, but underwater they can do over 30 knots. The old Russian ALFA class submarines were known to do 45 knots submerged.
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.
Water resistance is huge!!
its called water resistance in water
Sonar
To keep water from leaking in.
yes it is water resistance.....
No submarines do not explore the atmosphere. atmosphere means air. Sub means under, Marine means water.
