Arobotic submersible is being lowered into the water. what happens to the buoyant force as the submersible enters the water? write 2 - 3 sentences explaining your reasoning.

The buoyant force increases as the submersible enters the water, and it remains constant after the submersible is completely immersed.

Explanation:

The buoyant force acting on an object is given by:

where

is the density of the liquid

is the volume of the object immersed in the liquid

g is the gravitational acceleration

From the formula, we see that as increases, the buoyant force increases as well. Therefore, as the submersible is lowered into the water, the buoyant force gradually increases (because the immersed volume increases); however, when the submersible is completely immersed, no longer changes, so the buoyant force remains constant.
