At a point 13.0 m from a source of spherical sound waves, you measure a sound intensity of 790 mW/m2 . How far do you need to walk, directly away from the source, until the intensity is 220 mW/m2

11.6 m

Explanation:

The intensity of sound is inversely proportional to the square of the distance from the source. If we denote intensity with I and distance with d,

This can be resolved for any two situations as

Therefore, you need to walk 24.6 - 13 m = 11.6 m away from the source.

the answer is 3.1 his answer is wrong mines is right

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
