PLEASE AWNSER CORRECTLY AND ILL GIVE BRAINLIEST Two objects were lifted by a machine. Object A has a mass of 2 kilograms and was lifted at a speed of 2 m/s. Object B has a mass of 4 kg and was lifted at a rate of 3 m/s.
a. Which object had more kinetic energy while it was being lifted?

b. Which object had more potential energy when it was lifted to a distance of 10 meters?

Which best represents the law of conservation of mass ?

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)
