Fifth Harmonic-Standing Waves on a String
There are a variety of patterns that could be generates through vibrations inside a string, slinky, or rope. Every pattern corresponds to vibrations that occur at a particular frequency and is called as a harmonic. The lowest probable frequency at which a string could vibrate to form a standing wave pattern is called as the fundamental frequency or the first harmonic.

Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
A coil havingof a resistance of 100 and an inductance of 200mH. If an alternating voltage, v, givenby v=200sin500t volts is applied across the coil, measure (a) The circuit
