The string from the reading question is 2m meters long, has a mass of 7g, and is vibrating with a frequency of 100 Hz. a. What is the fundamental frequency of the string? b. What is the wave speed on the string? C. How tight does the string need to be to sustain this frequency?

Please select the correct statement about the amplitude of a wave. a. The amplitude of a wave can be either a positive or a negative value. b. The amplitude of a wave can be a negative value. C. The amplitude of a wave is always a positive value.

A piece of string AB is 7 m long with end B left free to move.  A is vibrated harmoniously up and down so that it travels on a string with a speed of 20 m/s.  If the 5th node is 4 m from the origin of the vibration, calculate: a.  the wavelength that propagates on the rope b.  the frequency of the resulting wave

A guitar string is vibrating in its fundam ental mode, with nodes at each end. The length of the segment of the string that is free to vibrate is 0.388 m. The maximum transverse acceleration of a point at the middle of the segment is 8100 m/s2 and the maximum transverse velocity is 3.60 m/s. a. What is the amplitude of this standing wave? b. What is the wave speed for the transverse traveling waves on this string?

One end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates the rope transversely at 120 Hz. The other end passes over a pulley and supports a 1.50 kg mass. The linear mass density of the rope is 0.0550 kg/m. A.) What is the speed of a transverse wave on the rope? B.) What is the wavelength? C.) How would your answers to A and B change is the mass were increased to 3.00 kg?

A piano wire of linear density 12 g/m has a length 2 m. It is stretched with a force of 7000N. A. What is the third harmonic of vibation of this wire? Draw a diagram. B. By what factor do you have to change the tension to get a fundamental mode at the same frequency.

A bat flying at 5.25 m/s is chasing an insect flying at 3.49 m/s in the same direction. The bat emits a steady chirp of frequency 2000 Hz. a. What frequency, f0, does the insect hear? b. The insect becomes a moving source at frequency f0. What frequency does the bat hear reflected from the insect? c. The bat hears its own sound, plus the sound reflected by the insect. What beat frequency does the bat hear?
