Question

What is the intensity level of the rustling leaves ?

Answer 1

20dB

Step-by-step explanation:

We were given the following details:

`\begin{gathered} dB=10log((I)/(I_o)) \\ I_o=10^(-12)w\text{/}m^2 \\ I=20dB=1*10^(-10) \\ dB=10log((1*10^(-10))/(1*10^(-12))) \\ dB=10log(100) \\ dB=10* log10^2 \\ dB=10*2log10^{} \\ dB=10*2 \\ dB=20 \\ \\ \therefore dB=20 \end{gathered}`

Therefore, the intensity of the rustling leaves is 20 decibels
