A 2.0-meter long rope is hanging vertically from the ceiling and attached to a vibrator. A single pulse is observed to travel to the end of the rope in 0.50 s. What frequency should be used by the vibrator to maintain three whole waves in the rope?

A transverse wave is traveling on a string. The displacement y of a particle from its equilibrium position is given by y = (0.021 m) sin(25t - 2.0x). Note that the phase angle 25t - 2.0x is in radians, t is in seconds, and x is in meters. The linear density of the string is 1.4 × 10-2 kg/m. What is the tension in the string? F= i

A person putting up power lines is told to stretch the wire between poles to a tension of about 800N. The person doesn't have a tension scale so they decide to measure the speed of a pulse created on the wire when they hit it with a wrench. The pulse travels from one pole 60m to another pole and back again in 2.6 s. The 60m long wire has a mass of 15kg. Should the wire be tightened or loosened? Explain how you decided. Thanks!

Two identical guitar strings are prepared such that they have the same length (0.67 m) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the fourth harmonic. The other string is plucked in a different location, primarily exciting the second harmonic. The resulting sounds give rise to a beat frequency of 369 Hz. What is the wave propagation speed on the guitar strings?

The linear mass density of a copper, 36.0cm long cable is 0.00750kg/m.The wire is fastened at each end. The speed of sound in air is 344m/s.

The wire’s tension is 254.8N. a)  Which harmonic is present in the standing wave? b) ) What is the velocity of the wave in the wire? c) ) What is the frequency of the wave? d) ) How far from the wire’s end is the first anti-node?

A string of mass 9 grams is stretched to a length of 0.4 meters and fastened at both end so that it can freely vibrate. The tension on the string is 2000 Newtons. What is the linear density of the string? kg/m Submit Answer Tries 0/2 At what speed would a wave propagate on this string? m/s Submit Answer Tries 0/2 What is the wavelength of the first harmonic (also called the fundamental frequency) of standing wave created by the vibrating string? Submit Answer Tries 0/2 What is the fundamental frequency of the vibrating string? Hz

What is the speed of a transverse wave on the rope if the mass were increased to 3.00 kg? What is the wavelength of a transverse wave on the rope if the mass were increased to 3.00 kg?

To measure the acceleration due to gravity on a distant planet, an astronaut hangs a 0.0723-kg ball from the end of a wire. The wire has a length of 1.41 m and a linear density of 3.62 × 10-4 kg/m. Using electronic equipment, the astronaut measures the time for a transverse pulse to travel the length of the wire and obtains a value of 0.112 s. The mass of the wire is negligible compared to the mass of the ball. Determine the acceleration due to gravity. Number i Units

A string is connected to an oscillator and then laid horizontally, with the other end draped over a pulley and a mass of 200g is hung from that end. The string is found to have a mass of 15g and a length of 1.2m. The oscillator is turned on and the frequency is tuned until a standing wave is seen. You see 6 full wavelengths along the 1.2m length of the string. The oscillator frequency is set to 63Hz. What is the speed of the wave on the string based on your measurements? Give your answer in m/s and to 1 decimal place.
