Week 3 - Homework---Spring 2022.pdf Week 3 Homework (1) Two speakers emit waves with amplitude 9.34m. The wave from the speaker on the left has a phase constant of 7r while the wave from the speaker on the right has a phase constant of g. They both have a wavelength of 2.73m and a frequency of 125.6Hz. The speakers are a distance of 7.63m from one another. (a) As a person walks in a circle of radius r = 19.1771 around the speaker on the left, at what distances from the speaker on the right will the person experience perfectly constructive interference? (b) If we were to redo the calculation in part (a) while changing only one of the quantities given in the problem, identify which of the quantities would change your results as well as which of the quantities would not change your results. As always, all answers require justication to receive full credit. Note: Any quantity not given in part (a) would be recalculated based on the new value of the changed variable. 1.

The EMT is completely stationary. It is quite an emergency, so the ambulance is approaching at 67.9mph and emitting its siren at a frequency of 74501-1 2. It is a hot day where it is 379C outside. (a) What is the frequency heard by the EMT? (b) What is the frequency of the echo off the hospital heard by the person driving the ambulance? That is, the sound has left the siren, bounced off of the hospital, and returned to the driver in the moving ambulance. _. 12 (5") Dashboard Calendar E To Do 0 Notifications glnbox
