6. An old Dutch legend has a small boy plug a leak in a dyke with his finger, saving the town from being flooded by the ocean. Let's examine this story to see if it is possible. Let's say the boy plugs a hole with area 1 cm^2, which is 6 m below sea level. The density of sea water is approximately 1030 kg/m^3, and the Atlantic Ocean contains approximately 3.5x10*17 m^3 of water. a) What would the water pressure be at the point of the hole? b) How much force would the boy have to apply to stop the water from flowing through the hole? c) Could he do it?
