63. (a) Since ω =2 πf , Eq. 18-15 leads to p m = (2 πf ) s m = s m = 1 . 13 × 10 3 Pa 2 π (1665 Hz)(343 m / s)(1 . 21 kg / m 3 ) which yields s m =0 . 26 nm. The nano prefx represents 10 9 . We use the speed oF sound and air density values given at the beginning oF the exercises and problems section in the textbook.
