Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Chapter 5.2, Problem 84E

Sound Intensity The relationship between the number of decibels β and the intensity of a sound I (in watts per square meter) is

β = 10 log I 10 − 12 .

a Determine the number of decibels of a sound with an intensity of 1 watt per square meter.

b Determine the number of decibels of a sound with an intensity of 10 − 2 watt per square meter.

c The intensity of the sound in part a is 100 times as great as that in part b . Is the number of decibels 100 times as great? Explain.
