What rms current flows in a 48 mH inductor when 111 V rms at a frequency of 23 KHz is applied to it?

The bending of a wave as it moves from one medium to another is called

Is it possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration?

How can resistance be useful and where can they be useful?

An electric heater works by passing a current of 112 amps through a coiled metal wire, causing it to become red hot. If the resistance of the wire is 0.95 ohms, what voltage must be applied to it?

Look at the diagram showing resistance and flow of electrons. A top box labeled X contains 2 circles with plus signs and 2 circles with minus signs. A bottom box labeled Y contains 4 circles with minus signs and 8 circles with plus signs.

Why does the speed of an object change when a force acts on it?

What are factors that would change the position of the wave lengths measured? (There are more than one answer.) a) size of the tube b) tuning fork frequency c) distance between the tuning fork and tube d) room temperature e) area of the tube
