A car accelerates uniformly from rest to 23 m/s over a distance of 30 meters. What is the acceleration of the car?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

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)

Is the number of complete movements of a wave per second.
