A male alligator emits a subsonic mating call that has a frequency of 18 Hz by taking a large breath into his chest cavity and then releasing it. If the hollow chest cavity of an alligator behaves approximately as a pipe open at only one end, estimate its length L.

Problem 2: When mass M is tied to the bottom of a long, thin wire suspended from the ceiling, the wire's second-harmonic frequency is 200 Hz. Adding an additional 1.0 kg to the hanging mass increases the second-harmonic frequency to 245 Hz. What is M?

A well with vertical sides and water at the bottom resonates at 7.00 Hz and at no lower frequency. (The air filled portion of the well acts as a tube with one closed end and one open end.) The air in the well has a density of 1.10 kg/m^3 and a bulk modulus of 1.33×10^5 Pa. How far down in the well is the water surface?

How long is this column of air if v = 354 m/s?

A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (a) What is the speed of sound in the flute? A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (b) What is the wavelength of the first harmonic? Consider the flute to be a pipe open at both ends  A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (c)Consider the flute to be a pipe open at both ends and find its length, assuming this frequency is the fundamental frequency A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. A second player, nearby in a colder room, also attempts to play middle C on an identical flute. A beat frequency of 3.00 beats/s is heard.  (e) What is the speed of sound in the second room? A flute is designed so that it plays a…

A copper wire, whose cross-sectional area is 8.58 x 106 m², has a linear density of 6.18 x 103 kg/m and is strung between two walls. At the ambient temperature, a transverse wave travels with a speed of 60.8 m/s on this wire. The coefficient of linear expansion for copper is 17 x 10-6 (Cº)-1, and Young's modulus for copper is 1.1 x 10¹1 N/m². What will be the speed of the wave when the temperature is lowered by 26.5 Cº? Ignore any change in the linear density caused by the change in temperature. Number i Units

If the vocal tract of a human is considered a closed tube 17 cm in length, what is the frequency of what would become the second harmonic? Consider 340 m/s as the speed of sound. The answer must be in Hz units.

Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). The P-waves have a speed of about 6 km/s. Estimate the average bulk modulus of Earth's crust given that the density of rock is about 2,800 kg/m3.

A sound wave with a frequency of 9800 Hz travels along a copper pipe. If thewavelength is 0.370 m and the density of copper is 8.9 x 10^3 kg/m^3, what is the elastic modulus of copper?

A ski gondola is connected to the top of a hill by a steel cable of length 660 m and diameter 1.5 cm. As the gondola comes to the end of its run, it bumps into the terminal and sends a wave pulse along the cable. It is observed that it took 17 s for the pulse to return. a) What is the speed of the pulse? b) What is the tension in the cable?
