Fourth 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 possible frequency at that a string could vibrate to form a standing wave pattern is called as the fundamental frequency or the first harmonic.
The idea that electrons revolved in orbits around the nucleus of an atom without radiating energy away from the atom was postulated by: a) Thompson b) Bohr c) Ruther
Because of concentration difference holes or electron try to vary from their side to other side. Only these holes or electrons cross the junction, having high kinetic energy. This

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:
MOTION: A body is said to be in motion if it alters its position with respect to its surroundings.
