Hoping I helped, and I would appreciate the brainliest answer! :)
Answer:
5.42 meters
Explanation:
Sound intensity varies inversely with the square of distance:
I = k / r²
When r = 5, I = 100.
100 = k / 5²
k = 2500
I = 2500 / r²
When I = 85:
85 = 2500 / r²
r = 5.42
Answer:
Weight = Force = Mass times acceleration of gravity
