Multiple Choice

Solve the problem.
-A certain noise has an intensity I of 4.01×1054.01 \times 10 ^ { - 5 } . Given that decibel level D is related to intensity by D=10log(II0) \mathrm { D } = 10 \log \left( \frac { \mathrm { I } } { \mathrm { I } _ { 0 } } \right) , where I0\mathrm { I } _ { 0 } is 101210 ^ { - 12 } , determine the decibel level of the noise. Round your answer to the nearest decibel.


A) 175 decibels
B) 76 decibels
C) 8 decibels
D) 66 decibels
