The pressure equalizes between a "bouyed" body, and the "bouying" fluid, such that the pressure of the fluid, integrated over the wetted surface, equals the weight of the body.
No, vacuum does not have a buoyancy force because buoyancy is a result of differences in pressure within a fluid. In a vacuum, there is no fluid to exert pressure so there is no buoyant force.
Buoyancy is not directly caused by pressure. Buoyancy is the upward force exerted on an object immersed in a fluid, such as water, due to the pressure difference between the top and bottom of the object. This pressure difference results in the object experiencing a net upward force, causing it to float or rise in the fluid.

No, because buoyancy is the upward force exerted on an object in a fluid due to the surrounding fluid pressure being greater at the bottom of the object than the top. Gravity is necessary to create this pressure difference that leads to buoyancy. Without gravity, there wouldn't be a pressure gradient to cause the buoyant force.
Depends on the weight of water. Salted water being heavier ,it will offer more resistance to any floating object. Also the atmospheric pressure might play an important role in the buoyancy.

Of true forces, pressure gradient force and buoyancy force play important roles in the formation of tornadoes.
Gradually but continuously exhale. This is not only to control buoyancy, but to prevent damaging your lungs as the air in your lungs expands (due to external pressure decreasing, internal pressure increases)
The force of atmospheric pressure on a blimp is what helps it to stay inflated and maintain its shape. The blimp is designed to have a higher pressure inside than outside, creating buoyancy that enables it to float in the air. Changes in atmospheric pressure can impact the altitude and stability of the blimp.
Gravity is needed for buoyancy as if there was no gravity then there would be no need for buoyancy, the need for buoyancy is to counteract the pull of gravity so you can stay at the surface of a liquid such as water. If there was no gravity then there would be no need to counteract it. I hope this the answer you needed. What if there is a ball of water in space and a cork made dof wood is inserted carefully into the ball. Would it 'rise' from the center of the ball towards the surface or not???
Yes in fact Pressure treated wood floats quite well do to the buoyancy in the grains.
