A computer monitor uses 240 W of power. The monitor is never turned off. If C=rPt, and the cost of electricity is $0.12/kWh, then what is the daily cost of operating the monitor?

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

What must be the same for any two resistors that are connected in series ? a. the potntial diffrence across each b. the rate at which charge moves through each c. the rate at which energy is used by each d. the resistance to the flow of charge of each
