Read the problem. A swimmer is at a depth of 10 meters in a freshwater lake. The density of freshwater is 1000 the fraction with numerator kg and denominator m cubed What is the pressure at this depth?

Use the pressure due to the water: P = ρgh. With freshwater density ρ = 1000 kg/m³, depth h = 10 m, and g ≈ 9.8 m/s², P = 1000 × 9.8 × 10 = 98,000 Pa. The pressure is 98,000 Pa, choice A.
