Sound intensity
the relationship between the number of decibles b and the intensity of a sound i (in watts per square centimeter) is given by
β = 10 log10 (i/10^-16).
find the rate of change in the number of decibles when the intensity is 10-4 watt per square centimeter.

Step-by-step explanation:

We are given that a relation between the number of decibles B and the intensity of a sound I

By using property

Log 10=1

We have to find the rate of change in the number of decibles when the intensity I=

Differentiate w.r.t I

Substitute

By using property
