Anew landowner has a triangular piece of flat land she wishes to fence. starting at the west corner, she measures the first side to be 80.0m long and the next to be 105m. these sides are represented as displacement vectors a and b in the above. she then correctly calculates the length and orientation of the third side, c. what is her result?

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.
