If a source radiates sound uniformly in all directions and you triple your distance from the sound source, what happens to the sound intensity at your new position

The new intensity becomes (1/9) of the initial intensity.

Explanation:

A source radiates sound uniformly in all directions and its intensity is proportional to the distance as follows :

Let I₁ and I₂ be the intensities at a distance r₁ and r₂. So,

We have, r₂ = 3r₁

Hence, the new intensity becomes (1/9) of the initial intensity.

1. metals

2. metalloids only

3. nonmetals only

4. metals and metalloids

5. metalloids and nonmetals

i just took this assignment so this is correct
