일반물리학 1 — Oscillations: Problem 41

41 A loudspeaker produces a musical sound by means of the oscillation of a diaphragm whose amplitude is limited to \(4.00 \, \mu\text{m}\). (a) At what frequency is the magnitude \(a\) of the diaphragm’s acceleration equal to \(g\)? (b) For greater frequencies, is \(a\) greater than or less than \(g\)?
