A balanced three-phase 60 Hz source supplies power to a balanced A-connected inductive load. The line voltage is 440 V, the line current is 8.2 A, and the power delivered to the load is 5 kW.

(a) Calculate the load impedance per phase.
(b) Find the complex power generated by the source
(c) What should be done to increase the power factor to unity? Give the value of any component added to the circuit (per phase).

1. jay fills a wagon with sand (about 20 kg) and pulls it with a rope 30 m along the beach. he holds the rope 25° above the horizontal. the rope exerts a 20-n tension force on the wagon. how much work does the rope do on the wagon?

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
