A thick power line of length 75 m is stretched taut between two poles, experiencing a tension force of 6250 N. The mass of the power line 750 kg. What is the maximum resonate frequency of the cable if the wavelength is exactly 1/3 the length of the cable?

A standing wave with 4 anti-nodes is set up in a string that has a linear mass density of 0.011 kg/m and pulled tight with a tension force of 1.7 N. If the string has a length of 1.3 meters, what is the frequency of this standing wave?

a 2.0-m cable under tension has a 12-kg mass. a standing wave of frequency 10 Hz has a wavelength of 0.40m. what's the cable's tension (in N)?

A 0.500-m string is clamped at both ends. If the lowest standing wave frequency in the string is 300 Hz, what is the wave speed?

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.

A transverse wave travels across a string having a linear mass density 0.065 kg/m. The wavelength of the wave is measured to be 0.71 m and the frequency is 52.5 Hz. What is the tension in the string?

A violin string with mass 0.35g is 35cm long. The frequency of a wave supported by the string is 196hz.  a) Assuming that this wave is a findamental frequency, what is the speed of the wave? b) What's the linear density of the string? c) Whats the tension in the string?

An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater. How deep is the water directly below the vessel if the time delay of the echo to the ocean floor and back is  8 s?

A guitar string has an overall length of 2.0 m and a total mass of 35.2 g before it is strung on a guitar. Once on the guitar, however, there is a distance of 85 cm between its fixed end points. It is tightened to a tension of 345 N. (a) What is wave speed for waves on the tightened string?  (b) What are the wavelength and frequency of the traveling waves that interfere to form the fundamental and second harmonic standing waves on the string? Sketch standing wave patterns of both harmonic in this string.

The linear density of a guitar string is 8.0 x 104 kg/m. A wave on the string has a frequency of 400 Hz and a wavelength of 60 cm. What is the tension in the string?
