A string on a guitar vibrates with a frequency of 440 Hz. Two beats are heard when this string and a string on another guitar are played at the same time. What are the possible frequencies of vibration of the second string?

A helium balloon has a volume of 2.00 L at 101 kPa. As the balloon rises the pressure drops to 97.0 kPa. What is the new volume?

When a guitar string plays the note "A," the string vibrates at 440 Hz. What is the period of the vibration?

Draw the resonance contributors of the cyclooctatrienyl dianion. a. Which of the resonance contributors is the least stable? b. Which of the resonance contributors makes the smallest contribution to the hybrid?

When a guitar string plays the note "A," the string vibrates at 440 Hz. What is the period of the vibration?

Determine which will change if you turn up a radio’s volume: wave velocity, intensity, pitch, amplitude, frequency, wavelength, or loudness.

An oscilloscope often displays a sawtooth curve. This curve can be approximated by sinusoidal curves of varying periods and amplitudes. Use a graphing utility to graph the following function, which can be used to approximate the sawtooth curve. $f(x)=\frac{1}{2} \sin (2 \pi x)+\frac{1}{4} \sin (4 \pi x), \quad 0 \leq x \leq 4$

Why would a passing car exhibit a greater sound frequency change when it moves at $30$ m/s than when it moves at $12$ m/s?

Conduction can occur in solids, liquids, and gases. Explain why solids and liquids are better conductors of heat than gases.

A guitar string vibrates harmonically with a frequency of 512 Hz (one octave above middle C on the musical scale). If the amplitude of oscillation of the centerpoint of the string is 0.002 m (2 mm), what are the maximum speed and the maximum acceleration at that point?

The period $T$ of a satellite circling Earth is given by $T^{2}=k R^{3}\left(1+\frac{d}{R}\right)^{3},$ where $R$ is the radius of Earth, $d$ is the distance of the satellite above Earth, and $k$ is a constant. Solve for $R,$ using fractional exponents in the result.

Explain how a flute, violin, and kettledrum produce sound.

Compare and contrast music and noise.

How long will it take for an undersea sonar pulse to travel 3 km?
