An ac series circuit has an impedance of 192 ω, and the phase angle between the current and the voltage of the generator is ϕ = −75°. the circuit contains a resistor and either a capacitor or an inductor. find the resistance r and the capacitive reactance xc or the inductive reactance xl, whichever is appropriate.

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.
