Answer 2

Answer:

The three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy.

Positive buoyancy is when the immersed object is lighter than the fluid displaced and this is the reason why the object floats.

Negative buoyancy is when the immersed object is denser than the fluid displaced which results in the sinking of the object.

Neutral buoyancy takes place when the weight of immersed object is equal to the fluid displaced. Dive taken by the scuba diver is an ideal example for neutral buoyancy.
