The relationship betwee the number of deibels "B"and the intensity of sound I in watts per squre centemiter is given by

B=20log(base 10)(I/10^-16)

a)Determine the number of deibels for intensity of 10^-4 watts persqure centimeter.

B)Determine the number of deibels for intensity of 10^-6.

C)The intensity of sound in parts a) is 100 times as great as that in part b) .Is the number of deibels 100 times as great?
