An air traffic controller observes two airplanes approaching the airport. the displacement from the control tower to plane 1 is given by the vector a⃗ , which has a magnitude of 220 km and points in a direction 32 ∘ north of west. the displacement from the control tower to plane 2 is given by the vector b⃗ , which has a magnitude of 140 km and points 65 ∘ east of north.

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

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.
