A ship is floating on a lake. Its hold is the interior space beneath its deck; the hold is empty and is open to the atmosphere. The hull has a hole in it, which is below the water line, so water leaks into the hold. The effective area of the hole is 6.2 × 10-3 m2 and is located 1.9 m beneath the surface of the lake. What volume of water per second leaks into the ship?
