Given that I0=10−12 watts/meter2, what is the intensity of a sound for which the decibel level of the sound measures 113?
Round off your answer to three decimal places.
:
The equation: 10*log(I%2F%2810%5E-12%29%29) = 113
divide both sides by 10
log(I%2F%2810%5E-12%29%29) = 11.3
the exponent equiv
(I%2F%2810%5E-12%29%29) = 10%5E11.3
I = 10%5E-12+%2A+10%5E11.3
Combine exponents
I = 10^-.7
I = .200 watts per square meter
