Hi! Can someone help me with the following question, I'ma little confused. Thank You! A celebrity holds a press conference, which is televisedlive. A television viewer hears the sound picked up by amicrophone directly in front of the celebrity. This viewer isseated 2.3 m from the television set. A reporter at the pressconference is located 4.1 m from the microphone and hears the wordsdirectly at the very same instant that the television viewer hearsthem. Using the value of 343 m/s for the speed of sound,determine the maximum distance between the television viewer andthe celebrity. Hi!

Explanation / Answer

This problem is just multiple applications of the simpleequation d=vt So first let's find the time for the reporter to hear thecelebtrity d=vt t=d/v =4.1/343 t=0.01192 sec Now we realize that a large portion of the time for the vieweris the time it takes for the sound to get form the tv to theperson t=d/v =2.3/343 t1=0.0067 sec That means that the time for the signal is0.0119-0.0067=0.0052 So now we solve for d d=vt =(3 x 108)(0.0052) d=1.558 x 106m Also something that would be good to take into account wouldbe that simultinaety is relative this means that our distance isonly correct relative to a point half-way between the two. (message me if you needed the relativity answer make sure youinclude the frame of refrence)
