Part a: Solve for the indicated value, and graph the situation showing the solution point. The formula for measuring sound intensity in decibels D is defined by the equation D=10log(II0) using the common (base 10) logarithm where I is the intensity of the sound in watts per square meter and I0=10−12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.2⋅102 watts per square meter? Part b: What is the correct graph for the situation?
