Concept explainers
Interpretation:
Total increase and the percentage increase in emission of
Concept Introduction:
Energy is the property that is required by an object to perform work and to heat itself and it can be measured.
The average change is calculated by dividing the change in the value by the elapsed time.

Answer to Problem 58E
Solution:
a)
The percentage increase in emission of
b)
The average percentage increase in
Explanation of Solution
a) The total increase in emission of
The percentage increase in emission of
The emission of
Substitute the value of emission of
Hence, the percentage increase in emission of
b) The average percentage increase of
The average percentage increase in
Substitute the value of emission of
Hence, the average percentage increase of
