The windpipe of a typical whooping crane is about 5.0 ft. long. What is the lowest resonant frequency of this pipe, assuming it is closed at one end? Assume a temperature of $37 ^ { \circ } \mathrm { C }$.

The overall length of a piccolo is 32.0 cm. The resonating air column vibrates as in a pipe that is open at both ends. Find the frequency of the lowest note a piccolo can play.

A stretched string of length L is observed to vibrate in five equal segments when driven by a 630-Hz oscillator. What oscillator frequency will set up a standing wave so that the string vibrates in three segments?

The Lacey Act (a) provides protected habitats for a number of threatened species. (b) forbids the interstate shipping of illegally harvested plants and animals. (c) provides harvesting quotas and prevents overharvesting. (d) prevents the spread of invasive species to the United States. (e) gives penalties for polluting ecosystems, especially water.

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. $\frac{1}{2} \div 4=2$____

Explain whether the experimental probability of tossing tails when a fair coin is tossed 25 times is always, sometimes, or never equal to the theoretical probability.

A family ice show is held at an enclosed arena. The skaters perform to music playing at a level of 80.0 dB. This intensity level is too loud for your baby, who yells at 75.0 dB. What is the combined sound level?

A steel wire in a piano has a length of 0.700 0 m and a mass of $4.300 \times 10 ^ { - 3 }$ kg. To what tension must this wire be stretched so that the fundamental vibration corresponds to middle C ($f_C$ = 261.6 Hz on the chromatic musical scale)?

Standing-wave vibrations are set up in a crystal goblet with four nodes and four antinodes equally spaced around the 20.0-cm circumference of its rim. If transverse waves move around the glass at 900 m/s, an opera singer would have to produce a high harmonic with what frequency in order to shatter the glass with a resonant vibration?

A family ice show is held at an enclosed arena. The skaters perform to music playing at a level of 80.0 dB. This intensity level is too loud for your baby, who yells at 75.0 dB. What total sound intensity engulfs you?

A guitarist sounds a tuner at 196 Hz while his guitar sounds a frequency of 199 Hz. Find the beat frequency.

A 4.0-m-long pipe, open at one end and closed at one end, is in a room where the temperature is T = 22°C. A speaker capable of producing variable frequencies is placed at the open end and is used to cause the tube to resonate. (a) What is the wavelength and the frequency of the fundamental frequency? (b) What is the frequency and wavelength of the first overtone?

A noisy machine in a factory produces sound with a levell of $80 \mathrm{~dB}$. How many identical machines could you add to the factory without exceeding the $90-\mathrm{dB}$ limit?

An earthquake can produce a seiche in a lake in which the water sloshes back and forth from end to end with remarkably large amplitude and long period. Consider a seiche produced in a farm pond. Suppose the pond is 9.15 m long and assume it has a uniform width and depth. You measure that a pulse produced at one end reaches the other end in 2.50 s. (a) What is the wave speed? (b) What should be the frequency of the ground motion during the earthquake to produce a seiche that is a standing wave with antinodes at each end of the pond and one node at the center?
