"a hiker starts at point p and walks 2.0 kilometers due east and then 1.4 kilometers due north. the vectors in the diagram below represent these two displacements.

using a metric ruler, determine the scale used in the vector diagram"

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.
