Answer and Explanation
Your Answer is
Correct Answer is A
Explanation
Substitute d=100 into simplification to get 10=log(I/10-12), 1010=I/10-12, so I=10-2, choose A
41. The number of decibels, d, produced by an audio source can be modeled by the equation d = 10 log
, where I is the sound intensity, in watts per square meter, of the audio source. What is the sound intensity, in watts per square meter, for an audio source that produces 100 decibels?
