The acceleration oF gravity is 9 . 8 m / s 2 and atmospheric pressure is 1 . 01 × 10 5 Pa . Correct answer: 5 . 3416 × 10 5 Pa. Explanation: Let : g = 9 . 8 m / s 2 , P atm = 1 . 01 × 10 5 Pa , h = 44 . 2 m , and ρ w = 1000 kg / m 3 . The pressure at the bottom oF the lake is equal to the pressure at the surFace plus the pressure given by the mass oF water above, so P = P atm + ρ w g h = 1 . 01 × 10 5 Pa + (1000 kg / m 3 ) (9 . 8 m / s 2 ) (44 . 2 m) = 5 . 3416 × 10 5 Pa ....
