The buoyant force is 135N
The question makes no sense. Objects are buoyant in a surrounding fluid; change the fluid, change their buoyancy.
Buoyant force, buoyancy force, buoyancy.
buoyant force
I think it is Buoyancy. Buoyant floats, neutral buoyancy neither floats nor sinks it is the same SG as the liquid in which it sits. Negative buoyancy sinks. Complete guesswork I'm afraid but there you go.
Objects that are in the middle of water have neutral buoyancy.
Buoyancy is linked to density, density being how much material is packed into an object of a certain size. Objects with less density will generally be buoyant in more dense objects.
These objects are called with "neutral buoyancy".
The upward force provided by water is called the buoyant force. Also known as the buoyancy force. Because of buoyant force, objects seem lighter in water.
Gravity is pulling down, and Buoyancy is pushing up. When the force of gravity is greater than the buoyant force, objects sink. When the buoyant force is greater than the force of gravity, objects float.
Buoyancy occurs in fluids, which are gases and liquids. Hot air balloons are buoyant in air and ships are buoyant in water for examples. When the buoyancy of objects exceeds the weight of those objects, the objects rise. When the weight exceeds the buoyancy they sink. And when the buoyancy equals the weight of the objects they float.
That force is bouyancy. Bouyancy is also present in a gas, but its effects are usually negligible except on objects with very low densities.
the objects that are buoyancy are the objects that have the force to rise or to float in any way.
