Hello. I was hoping someone could give me a direction to go with this homework problem. I'm having trouble trying to figure it out. Here's the question:
Two people relaxing outdoors listen to a bird sing. One person, only 1.00m from the bird, hears the sound with an intesity of 2.80x10^-6 W/m^2. (a) What is the power output of the bird's song? (b) What intensity is heard by a second person, which is 4.25m from the bird?
The answer I get doesn't correlate with the correct answer given. This is what I did for the first part. I can't solve the second part w/o the correct power from the first.
Intensity=Power/Area
P=IA
P=2.80x10^-6(1m) = 2.80x10^-6
Can anyone give me a clue of another direction to go? The answer for part (a) is 3.52x10^-5.
Thank you!
