CHAPTER 15 Sound - Mr. Nguyen's Website

Resonance on Strings A violin sounds a note of F sharp, with a pitch of 370 Hz. What are the frequencies of the next three harmonics produced with this note? A string’s harmonics are whole number multiples of the fundamental, so the fre-quencies are: Chapter 15 continued. f 2! 2f 1! (2)(370 Hz) ! 740 Hz f 3! 3f 1! (3)(370 Hz) ! 1110 Hz

6. An airplane passenger carries a 215-N suit-case up the stairs, a displacement of 4.20 m vertically, and 4.60 m horizontally. a. How much work does the passenger do? Since gravity acts vertically, only the vertical displacement needs to be considered. W! Fd! (215 N)(4.20 m) ! 903 J b. The same passenger carries the same suitcase back down the ...
