In Newtons famous event that why, apple always falls to the Earth. Suppose the weight of the apple is 2.5 N. Then calculate the force that does the apple exert on the Earth and also mention the direction of the calculated force?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
