Answer:
20dB
Explanation:
We were given the following details:
[tex]\begin{gathered} dB=10log(\frac{I}{I_o}) \\ I_o=10^{-12}w\text{/}m^2 \\ I=20dB=1\times10^{-10} \\ dB=10log(\frac{1\times10^{-10}}{1\times10^{-12}}) \\ dB=10log(100) \\ dB=10\times log10^2 \\ dB=10\times2log10^{} \\ dB=10\times2 \\ dB=20 \\ \\ \therefore dB=20 \end{gathered}[/tex]
Therefore, the intensity of the rustling leaves is 20 decibels
