1. an object in free fall will have an initial velocity equal to zero when: a. it is thrown vertically down
b. it is dropped
c. it's thrown up
d. it is released horizontally

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

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 = 2.1 m below the tank bottom which is a = 7.4 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)
