Question

A robotic submersible is being brought back on board a ship. What happens to the buoyant force as the submersible is lifted out of the water? Write 2-3 sentences explaining your reasoning.

Answer 1

The buoyant force acting on a robotic submersible decreases as it is lifted out of the water.

Step-by-step explanation:

As a robotic submersible is lifted out of the water, the buoyant force acting on it will decrease.

This is because the buoyant force is the force exerted by a fluid on an object immersed in it, and it is equal to the weight of the fluid displaced by the object. As the submersible is lifted out of the water, it displaces less and less fluid, resulting in a decrease in the buoyant force.
