How can a scuba diver keep from floating back to the surface of the water?

Explanation

To understand how a scuba diver can prevent themselves from floating back to the surface of the water, we need to consider the concepts of buoyancy and weight. Here’s a step-by-step solution:

### Step 1: Understanding Buoyant Force
The buoyant force is the upward force exerted by a fluid on an object that is submerged in it. According to Archimedes' principle, this force is equal to the weight of the fluid that the object displaces. The formula for buoyant force (FB) is given by:
\[ FB = \rho \times V \times g \]
where:
