Answer:![I_2=0.618\times 10^{-7} W/m^2](https://tex.z-dn.net/?f=I_2%3D0.618%5Ctimes%2010%5E%7B-7%7D%20W%2Fm%5E2)
Explanation:
Given
Distance between source and receiver ![d_1=3 m](https://tex.z-dn.net/?f=d_1%3D3%20m)
Sound Intensity ![I_1=1.1\times 10^{-7} W/m^2](https://tex.z-dn.net/?f=I_1%3D1.1%5Ctimes%2010%5E%7B-7%7D%20W%2Fm%5E2)
Distance of of second observer ![d_2=4 m](https://tex.z-dn.net/?f=d_2%3D4%20m)
Intensity varies as
![I\propto \frac{1}{d^2}](https://tex.z-dn.net/?f=I%5Cpropto%20%5Cfrac%7B1%7D%7Bd%5E2%7D)
using this
![I=\frac{k}{d^2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7Bk%7D%7Bd%5E2%7D)
![\frac{I_1}{I_2}=\frac{d_2^2}{d_1^2}](https://tex.z-dn.net/?f=%5Cfrac%7BI_1%7D%7BI_2%7D%3D%5Cfrac%7Bd_2%5E2%7D%7Bd_1%5E2%7D)
![\frac{1.1\times 10^{-7}}{I_2}=\frac{4^2}{3^2}](https://tex.z-dn.net/?f=%5Cfrac%7B1.1%5Ctimes%2010%5E%7B-7%7D%7D%7BI_2%7D%3D%5Cfrac%7B4%5E2%7D%7B3%5E2%7D)
![I_2=0.75^2\times 1.1\times 10^{-7}](https://tex.z-dn.net/?f=I_2%3D0.75%5E2%5Ctimes%201.1%5Ctimes%2010%5E%7B-7%7D)
![I_2=0.618\times 10^{-7} W/m^2](https://tex.z-dn.net/?f=I_2%3D0.618%5Ctimes%2010%5E%7B-7%7D%20W%2Fm%5E2)
