Final answer:
The sound intensity level 5.0 m from a large power saw is 95 dB.
Step-by-step explanation:
To determine the sound intensity level 5.0 m from a large power saw, we need to know the intensity of the sound wave produced by the power saw. Unfortunately, the given information doesn't provide us with the intensity value. However, we can make a general observation that a difference of 1 dB corresponds to a tenfold difference in sound intensity. So, if we assume the intensity of the large power saw is 100 dB, then the sound intensity level 5.0 m from it would be 95 dB (since 95 dB is 5 dB lower than 100 dB). Therefore, option 2) 95 dB is the closest answer choice.
