Buoyancy can work in any liquid provided that the object floating weighs less than the liquid it displaces. This is true regardless of whether it is water or not!
Buoyancy works in any fluid. The fluid can be any liquid, or any gas.
All objects have buoyancy when imersed in any liquid.
Drag (water and air), gravity, displacement buoyancy, aerodynamic lift,
Buoyancy compensators are typically used for compensating things such as buoyancy things. These things need to be compensated very often to work properly.
Gravity pulls the water down more than it pulls the boat down.
No........buoyancy.

No chance of buoyancy force in free space. Buoyancy is the force is due to the weight of the expelled fluid when an object comes into that fluid. But in free space no material is present and so no expelling. Hence no buoyancy.
A marge ship, like an ocean liner, may be incredibly heavy. But the weight of something isn't the only thing that will determine if it sinks or floats. Buoyancy is also very important. Think about when you're in a pool and you hold your breath - you can actually float on your back for a little while. this is because the air in your lungs is providing you with buoyancy - essentially pushing you up out of the water*. Well, ships operate the same way - the inside of a ship is mainly hollow and filled with air, giving it the buoyancy necessary to float. * - Coincidentally, this is how hot air balloons work, too. The hot air in the balloon is lighter than the air around it, and provides buoyancy. Science!
A bathing suit, of course, is essential equipment for water aerobics, something that is comfortable enough and flexible enough to work out in. Other equipment for water aerobics includes aquatic dumbbells and a buoyancy belt.
Yes but you have to only wear the jackhammer Helmet nothing else or else it wont work.
Negative buoyancy is when the gravitational pull on a diver is greater than the buoyant force. This means that the diver is being pulled downward, and that the buoyant force is doing negative work (work that is in the opposite direction of the displacement). Positive buoyancy is the opposite situation in which the buoyant force of the diver is greater than the gravitational pull, which makes the diver move upwards. Usually, a person's weight is slightly more than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. As for your question whether this negative buoancy is a unique feature for black people, the answer is no. it is related to the person's density.
A diver needs a bcd to control where he is at in the water column. If a diver was to go in the water without one they would be relying only the buoyancy of there own body and the tanks which would make them negatively buoyant and that would take a lot of work to move around and stay off the bottom. With the bcd you can make it so that you can float effortlessly in the water where you want and move back and forth and side to side with just the flick of your hands or fins. experience: U.S. Army Deep Sea Diver
