What is voltage, and what is its relationship to amperage and power?

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

Atoy airplane, flying in a horizontal, circularpath, completes 10. complete circles in 30.seconds. if the radius of the plane’s circular pathis 4.0 meters, the average speed of the airplane is(1) 0.13 m/s (3) 1.3 m/s(2) 0.84 m/s (4) 8.4 m/s

Using the scale of one division =20lb of force find the value of the resultant force in the diagram
