A 4.0 ohm resistor draws 3.6 coulombs. What is the potential difference in the circuit? A. 0.80 V
B. 1.1V
C. 75V
D. 14 V

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
