Exact Steps On How To Solve With The Addition On How To Properly Input Log10 class=

Answer :

Answer:

Explanation:

log10 function is required to convert dB into intensity of a sound. Both are measures of loudness of a sound and the relationship can be expressed as follows:

dB = 10 log10(I/Io), where Io is 10^-12 W/m^2

Substituting, 82 = 10 log10(I/10^-12)

I = 0.0001585 W/m^2

or 1.58*10^-4 W/m^2

Answer:

Explanation:

82dB = 10log(Intensity/10^-12)

Intensity = 10^-12*10^(82/10)

=10^(-3.8)

=1.585*10^-4 W/m2
