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.

A circular coil has a 12.8cm radius and consists of 29.0 closely wound turns of wire. An externally produced magnetic field of magnitude 2.23 mT is perpendicular to the coil. (a) i
Self inductance: When current through a coil changes, the changing flux induces an emf that opposes the current flow. This emf is the result of self inductance and is called '
if electrons are moving from east to west in a conductor is there a flow of current?
