The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.
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
