Solve the Problem $L=10 \cdot \log \frac{I}{I_{0}}$ , Where the Loudness of a Sound in Decibels Is

Multiple Choice

Solve the problem.
-Use the formula $L=10 \cdot \log \frac{I}{I_{0}}$ , where the loudness of a sound in decibels is determined by $I$ , the number of watts per square meter produced by the sound wave, and $\mathrm{I}_{0}=10^{-12}$ watts per square meter. What is the intensity of a noise measured at $93 \mathrm{db}$ ?

A) $1.09 \times 10^{16}$ watts per square meter
B) $2 \times 10^{-2}$ watts per square meter
C) $9.3 \times 10^{-10}$ watts per square meter
D) $2 \times 10^{-3}$ watts per square meter
