How does a submarine works that floats then sinks and then again floats?
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
Differences between a ship and a submarine?
a ship floats on the water and a submarine can go underwater and on top of the water
When a submarine pumps water out of its floatation tanks its density decreases and it floats?
Yes, when a submarine boat pumps water out of its flotation (not floatation) tanks, the submarine should rise.
When a submarine pumps water out of its floatation tank its density decreases and it floats why?
because of density
How does a submarine change its buoynacy so it can float or sink?
This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.
How do you make a miniature submarine for a 7th grade project?
Take some toast weigh it down and stab something through it that floats. Itwill get soggy underwater and release the floating object
Is a submarine a modern invention?
The first successful submarine was built in 1620 by Cornelius Jacobszoon Drebbel, a Dutchman in the service of James I of England - it may have been based on Bourne's design. It was propelled by oars and is thought to have incorporated floats with tubes to allow air down to the rowers.
Will the submarine sink or float when its weight is equal to the upthrust acting on it?
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
How submarine caused to submerge without use propulsion propeller and fins?
A submarine can submerge by filling ballast and trimmer tanks with sea water. The additional weight will take the submarine down. To resurface, the submarine will blow the sea water out of the tanks using compressed air. The air in the tanks make the submarine buoyant, so it rises and floats on the surface. Though a stationary submarine can submerge in this way, it usually submerges going forward and using diving plane (fins) to steepen the dive, so getting under the surface faster.
Why are the fins on the submarines are used?
They are actually called "planes" on a submarine and allow it to maneuver underwater. Horizontal "planes" allow the submarine to go up/down, vertical "planes" allow the submarine to go left/right.
Where can you find submarine in gta san Andreas?
Just type in down ,up,up,up,r2,L2, L2
What is a trim ballast tank?
That is a ballast tank used to alter the angle of the submarine up or down
