Question

1. Which of the following statements is true?
(A) Buoyant force is created only by water.
(B) Buoyant force is created only by liquids.
(C) Air cannot create buoyant force.
(D) Any liquid or any gas can create buoyant force.​

Answer 1

Answer:

Because the volume is the same at any depth, and the density of water is the same at any depth, the total mass of displaced water (mass = volume x density) is the same at any depth—making the buoyant force constant.
