A tension is applied to a 4-g string that is 0.39 m. The string vibrates at 552 Hz, this frequency representing the third harmonic. What is the tension in this string, in newtons?

A stretched string fixed at each end has a mass of 32.0 g and a length of 8.40 m. The tension in the string is 50.0 N. (a) Determine the positions of the nodes and antinodes for the third harmonic. (Enter your answers from smallest to largest distance from one end of the string.) nodes: antinodes: EEEE EEE (b) What is the vibration frequency for this harmonic? Hz

A thin 1.0-m metal rod sustains a longitudinal standing wave with vibration antinodes at each end of the rod. There are no other antinodes. The density and Young's modulus of this metal are, respectively, 2900 kg/m3 and 4.5x1010 N/m2. What is the frequency of the rod's vibration?

Two strings both vibrate at exactly 800 Hz. The tension in one of them is then increased slightly. As a result, six beats per second are heard when both strings vibrate. What is the new frequency of the string that was tightened?

A stretched string fixed at each end has a mass of 40.0g and a length of 8.00m. The tension in the string is 49.0N. (a) Determine the positions of the nodes and antinodes for the third harmonic. (b) What is the vibration frequency for this harmonic?

Two piano strings are played together producing 3 beats per second. The pitch of the first string is then raised by tightening it until its frequency is 280 Hz. When the strings are now played   they produce 4 beats per second. What the   is the frequency of vibration of the second string?

The height of the speaker stack was designed to be equal to the wavelength of the sound wave produced by the lowest string.    If the frequency of this harmonic vibration is 31 Hz and the length of the string is 0.89m (89cm), what is the speed of the ave on the string?    If the density of the string is 0.0657 kg/m what is the Tension of the string?    If the speed of sound is 343 m/s what will be the wavelength of the sound made by the first harmonic vibration (hint: this is the height of the tallest stack of speakers)

The speed of sound in a solid medium is given by the formulae v = VElp where E is the value of Young's modulus for the solid and p is the density. A sound wave travels at 5.8 x 10 m/s in a steel rod of length 1.00 m, diameter 2.0 cm and mass 7.0 kg. Use the data to determine the value of the Young's modulus for steel. Give your answer in giga-pascal (GPa, 109 N per m2).

650 Hz, and the train travels 16. A 12m rope is pulled tight with a tension of 92N. When one end of the rope is given a "thunk" it takes 0.45 sec. for the disturbance to propogate to the other end. What is the mass of the rope?

A violin string vibrates at 659.3 Hz when its full length is allowed to vibrate. If it is now held so that three-fifths of it is allowed to vibrate in the same harmonic, what frequency will it produce? Hz
