AP Physics 1
8.3 Fluids and Newton’s Laws
8.1 Internal Structure and Density
A scuba diver and their equipment have a combined mass of \(78 \text{ kg}\) and a volume of \(0.075 \text{ m}^3\). The diver wears a weight belt containing \(6.0 \text{ kg}\) of solid lead weights of density \(1.2 \times 10^4 \text{ kg/m}^3\) and carries an inflatable buoyancy compensator bladder of negligible mass. The diver is completely submerged in a freshwater lake where the water density is \(1.0 \times 10^3 \text{ kg/m}^3\). What volume of air must be inside the buoyancy compensator bladder for the diver to achieve neutral buoyancy?
