A particle with restoring force proportional to displacement and resisting force proportional to velocity is subjected to a force F sin ω0t. If the amplitude of the particle is maximum for ω = ω1 and the energy of the particle is maximum for ω = ω2 then (where ω0 natural frequency of oscillation of particle)
A loudspeaker diaphragm 0.2 m in diameter is vibrating at 1 kHz with an amplitude of 0.01 * 10^-3 m. Assume that the air molecules in the vicinity have the same amplitude of vibration.
