What was the magnitude of his displacement? Please include the number and unit.
What was the direction of his displacement? Please abbreviate (N, S, E, W, etc.)

Work = force × a. work b. energy c. distance d. momentum

Convection currents are caused by differences in what two things?

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.
