How far below the surface of water do you need to dive to double the atmospheric pressure? (Note: Atmospheric pressure is P_atm = 1.01 × 10⁵ Pa, and density of water is ñ = 1000 kg/m³.)

To double the atmospheric pressure, the pressure from the water column must equal 1 atm. Using the formula P = ρgh, where ρ = 1000 kg/m³, g = 9.81 m/s², and P = 1.01 × 10⁵ Pa, solving for h gives approximately 10 m.
