Aparticular 60 hz ac induction motor requires some phase delay to operate properly. the real power is 60 kw under a full load that includes real work, heat, vibration and noise. the motor was designed to operate with an 85% power factor (pf) when fully loaded, because some phase difference between voltage and current is necessary to establish the magnetic field in the motor. compute the motor's effective resistance r (with units) given the real power consumed at 240v ac is 60 kw a) b) to produce a capacitive reactance x-1 ohm, what capacitance would be needed at c) 60 hz? (4 pt) compute the capacitive reactance x that must be added in order to increase the power factor to 100% for 240 v and give units.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
