Find the speed of waves on a violin string of mass 800 mg and length 22.0 cm if the fundamental frequency is 920 Hz.

When the door of the Chapel of the Mausoleum in Hamilton, Scotland, is slammed shut, the last echo heard by someone standing just inside the door reportedly comes 15 s later. (a) If that echo were due to a single reflection off a wall opposite the door, how far from the door is the wall? (b) If, instead, the wall is 32.0 m away, how many reflections (back and forth) occur?

The A string on a string bass is tuned to vibrate at a fundamental frequency of 55.0 Hz. If the tension in the string were increased by a factor of four, what would be the new fundamental frequency?

Ultrasound equipment used in the medical profession uses sound waves of a frequency above the range of human hearing. If the frequency of the sound produced by the ultrasound machine is f = 30 kHz, what is the wavelength of the ultrasound in bone, if the speed of sound in bone is v = 3000 m/s?

A string that is under $54.0 \text{ N}$ of tension has a linear density $5.20 \ \dfrac{\text{g}}{\text{m}}$. A sinusoidal wave with an amplitude $2.50 \text{ cm}$ and wavelength $1.80 \text{ m}$ travels along the string. What is the maximum velocity of a particle on the string?

The _________ function copies one string to another.

For a violin, estimate the length of the portions of the strings that are free to vibrate. The frequency of the note played by the open E5 string vibrating in its fundamental standing wave is 659 Hz. Use your estimate of the length to calculate the wave speed for the transverse waves on the string.

True or False: The contents of a string object cannot be changed.

Explain how bowing a violin string gets it to vibrate.

He cited the recent string of burglaries as a reason for...

Explain why or why not. Which has more energy: a vibrating string at $30 \mathrm{~Hz}$ or the same vibrating string at $70 \mathrm{~Hz}$ ?

Latasha and Markisha are flying kites on a windy spring day. Latasha has released 250 feet of string, and Markisha has released 225 feet of string. The angle that Latasha's kite string makes with the horizontal is $35^{\circ} .$ The angle that Markisha's kite string makes with the horizontal is $42^{\circ} .$ Which kite is higher and by how much?

A state trooper chases a speeder along a straight road; both vehicles move at 160 km/h. The siren on the trooper’s vehicle produces sound at a frequency of 500 Hz. What is the Doppler shift in the frequency heard by the speeder?
