Minimized pure resistance, R, arm BC resistance of 800 ohms in parallel with a capacitor of 0.5uF;
arm CD, a resistance of 400 ohms in series with a capacitor of 1.0uF; and arm DA, a
resistance 1000 ohms.
(1) Obtain the value of the frequency for which the bridge can be balanced by first
deriving the balance equations connecting the branch impedance and
(ii) Calculate the value of the resistance in arm AB to produce balance.​

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.
