Consider a 1 meter-long string with a mass of 50 g attached to a string vibrator. The tension in the string is 80 N. When the string vibrator is turned on, it oscillates with a frequency of 64 Hz and produces a sinusoidal wave on the string with an amplitude of 4 cm and a constant wave speed. Give your answers to 3 sig fig. A)VWhat is the linear density of the medium?____kg/m B)What is the wave speed?____m/s C)What is the angular frequency?______Hz D) What is the time-averaged power supplied to the wave by the string vibrator?___W
What is the frequency of the fundamental? What is the wave speed?
On a guitar a typical string is 64 cm long and fixed on both ends. The E string has a frequency of 330 Hz. What is the wavelength of the wave on this string when strummed. (B) what is the velocity of the wave on the string. Placing a finger on the 5th fret shortens the string length to 48cm and changes the note to an A. What is the new fundamental frequency
There is a horn which has to work at 20 kHz and its length is to be half the wave length of the vibration. At the transducer end, the horn has a cross section of 8×8 cm2 and from this cross section two of the sides exponentially reduce to 4 mm. The other two sides remains at 8 cm only. If the velocity of sound in the medium is 4800 m/s, find what is the length of the horn?
One end of a horizontal hope is attached to a prong of an electrically driven tuning fork that vibrates the rope transversely at 150 Hz. The other end passes over a pulley and supports a 2.50-kg mass. The linear mass density of the rope is 0.05 kg/m. What is the wavelength in millimeters? NOTE Express your final answers accurate to four decimal places; avoid rounding off intermediate values in the solutions to avoid deviation due to rounding-off within the solution.
A string has a mass attached to it as shown in the figure. The length of the entire string is 2.4 m, and its mass is 12 gram. The hanging mass attached to the string is M = 4 kg. 1/4 of the length of the string is in the hanging part (vertical) and 3/4 is parallel to the table. The string in the horizontal part is plucked, and standing waves are observed in the third harmonic. Calculate the frequency of vibrations in the string (in Hz), and what will be the speed of the wave in the string? Enter the speed in m/s as your answer in canvas. |M kg
