- I need help on the last two parts. Thank you!A new band sensation is playing a concert and recording it for a live album to be released this summer. The band asks the sound mixer if he can autotune the singer who has a habit of singing slightly lower than the note. What would the mixer need to do to the sound wave? How would it affect the characteristics of the wave?9. Two small stereo speakers are driven in step by the same variable- frequency oscillator. Their sound is picked up by a microphone arranged as shown in the figure. For what two lowest frequencies above 100 Hz does their sound at the speakers produce (a) constructive interference and (b) destructive interference? (Given sound speed 345 m/s.) 2.00 m 4.50 m Microphone
- 3.) Consider a system like the one below. You want to measure the mass density of a cord. Understanding the relationship between wave speed and tension in a string, you decide to hang a 10 kg mass from the end of the string as shown. When you pluck the now tensioned string, you hear a note. You measure the frequency of the note with an app on your phone, finding it to be 130 Hz. What is the mass density of the string? 1 m 10 kg mgPlease help. Thank you The longest "string" (a thick metal wire) on a particular piano is 2.00 m long and has a tension of 375 N. It vibrates with a fundamental frequency of 27.5 Hz. What is the total mass of the wire?ZOOM + 1) Suppose we have an air column 80cm long with one open end and one closed end. (a) Find (i.e. derive) an expression for the resonant frequencies of the air column in terms of the length L of the air column, the speed of sound v, and the harmonic number n. Don't simply write the equation – show me how you obtain it by sketching several resonant standing waves. (b) What are the three lowest resonant frequencies in this air column (numerical values)? Take the speed of sound in air to be 343 m/s.
- Please help for this question!12. In the arrangement shown, a mass can be hung from a string (with a linear mass density of H = 0.002 */m) that passes over a massless pulley. The string is connected to an oscillator of constant frequency f. The length of the string between the oscillator and pulley is L = 2.00 m. When the mass is either 16 kilograms or 25 kilograms, standing waves are observed; however, no standing waves are observed with any mass between these values. (a) What is the frequency of the oscillator? (hint: the heavier the mass, the fewer the number of nodes) (b) What is the largest mass for which standing waves can be observed?
