Solve the problem.Use the formula D = 10.0 log (S/S0), where the loudness of a sound in decibels is determined by S, the number of watt/m2 produced by the soundwave, and S0 = 1.00 × 10-12 watt/m2. What is the intensity in watt/m2 of a noise measured at 84 decibels? (Round to an appropriate number of significant digits.)
A. 8.4 × 10-10 watt/m2 B. 2.5 × 10-3 watt/m2 C. 2.5 × 10-4 watt/m2 D. 4.4 × 1015 watt/m2
