A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 18 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 0.13 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 346 m/s,...

A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 19 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 0.16 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 345 m/s,...

006 10.0 points A copper rod is given a sharp compressional blow at one end. The sound of the blow, traveling through air at -3.43 °C, reaches the opposite end of the rod 6.2 ms later than the sound transmitted through the rod. What is the length of the rod? The speed of sound in copper is 3780 m/s and the speed of sound in air at -3.43 °C is 331 m/s. Answer in units of m.

rage of 5 Problem 2: The speed of sound in a certain metal is vm. One end of a long pipe of that metal of length L is struck a hard blow. A listener at the other end hears two sounds, one from the wave that travels along the pipe's metal and the other from the wave that travels through the air inside the pipe. (a) If v is the speed of sound in air, what is the time interval...

Chapter 17, Problem 058 A sound source A and a reflecting surface B move directly toward each other. Relative to the air, the speed of source A is 28.9 m/s, the speed of surface B is 64.3 m/s, and the speed of sound is 326 m/s. The source emits waves at frequency 1230 Hz as measured in the source frame. In the reflector frame, what are (a) the frequency and (b) the wavelength of the arriving sound waves? In the...

BACK NEXT Chapter 17, Problem 050 GO A tube 1.30 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.351 m long and has a mass of 9.70 g. It is fixed at both ends and oscillates in its fundamental mode. By resonance, it sets the air column in the tube into oscillation at that column's fundamental frequency. Assume that the speed of sound in air is 343 m/s, find...
