By comparing the frequency of a received echo with the known frequency of the emitted sound, SONAR units on submarines can determine the locations and velocities of other ships. Suppose a submarine that is virtually at rest emits a pulse of sound at a frequency f through water at the speed of sound v. What would be the frequency detected by a fast surface vessel, approaching at a speed of 0.08 v? 0.93 f A B. 0.92 f 1.08 f 1.008 f

calculate the reverberation time at 500hz for a conference room that is 12 ft wide, 20 ft long and 12 ft high. It has a carpeted floor, curtains on both sides, plasterboard (or equivalent) short sides, and a plasterboard ceiling. what will the reverberation tiume be if it is occupied by twenty people in comfortable upholstered seats?
Radio-controlled clocks throughout the United States receivea radio signal from a transmitter in Fort Collins, Colorado,that accurately (within a microsecond) marks the beginningof each minute. A slight delay, however, is introducedbecause this signal must travel from the transmitter to theclocks. Assuming Fort Collins is no more than 3000 km fromany point in the U.S., what is the longest travel-time delay?
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 576.6 nm had been shifted to green with a wavelength of 562.3 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits. fO ≈ fS (1 ± u/c) if u < c what is the frequency in m/s?
