Problem: Two people hear a tornado siren, but one listener is 22.5 times farther away from the source of the sound than the other.
Part A: What is the intensity level (in dB) at the farther listener relative to the other listener?
I need proficient help in the above problem.
For a spherical celestial object of radius R, the acceleration due to gravity g at a distance x from the center of the object is g = g0R2/x2, where g0 is the acceleration due to gravity at the object's surface and x > R. For the moon, take g0 = 1.63 ..
