What is a submarine scope?
A submarine scope, often referred to as a periscope, is an optical instrument used in submarines to allow personnel to view the surface of the water while remaining submerged. It consists of two mirrors or prisms that redirect light from above the water's surface down to the viewer inside the submarine. This enables submarines to conduct surveillance and navigation without exposing themselves to enemy detection. Modern submarine scopes may also include advanced technology, such as cameras and sensors, for enhanced observation.
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.
How does a submarine dive under water from the surface?
Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
How do you use periscope in a sentence?
Periscopes allow a submarine, when submerged at a shallow depth, to search visually for nearby targets and threats on the surface of the water and in the air. When not in use, a submarine's periscope retracts into the hull.
What was a submarine's basic purpose?
The submarine had been envisioned by ancients as a weapon to be used against surface ships. Hundreds of years went by before technology allow construction of one. The "real" boats were around in a limited way in WWI, but by WWII, they kicked butt. Today, we have superb military submarines. The submarine was also seen as a research vessel and a recreational vehicle before they advent of the "real" submarine.
How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
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.
Has the buoyant force on a diving submarine been reduced?
Yes, the buoyant force on a submarine has been reduced to allow it to "stop floating" and submerge.
Mould or carve a decoration that is raised above the surrounding surface?
To create a raised decoration, you can carve or mold the design onto the surface using clay, wood, or plaster. Once the design is shaped to your liking, allow it to dry or set before attaching it to the desired surface using an adhesive or by embedding it during the surface's construction.
What is the function of the ballast tanks on a submarine?
To change the buoyancy of the boat and allow it to rise and sink in the water.
What surface appendages that allow a bacterium to stick to a surface.?
pili
What happens inside a submarine to cause it to sink?
They open valves to allow seawater to enter the ballast tanks outside.
