A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.00 cm in diameter. (a) If the hole was 1.40 m below the surface of the North Sea (density 1030 kg/m), what was the force on his finger? N (b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth of 1 ft assuming the hole remained constant in size?
