Answer:
Restoring force is a force which acts to bring a body to its equilibrium position. The restoring force is a function only of position of the mass or particle, and it is always directed back toward the equilibrium position. Therefore the restoring force of air particles should be displaced in the direction of the force and according to Newton 3rd law of motion, once the force is removed, restoring force of elasticity returns the displaced particle to a resting state .
