a.
To explain: The meaning of uncertainty in the context of the problem.
a.

Answer to Problem 28HP
The uncertainty is the error in the measurement so an uncertainty of
Explanation of Solution
Given:
The thickness of a page in a textbook was measured with a micrometer to be 0.018 centimeter. The micrometer’s measurement has an uncertainty of plus or minus 0.001 centimeter.
Calculation:
The uncertainty is the error in the measurement so an uncertainty of
b.
To explain: The accuracy of the thickness of the page need to publishing the textbook.
b.

Answer to Problem 28HP
0.001 cm.
Explanation of Solution
Given: The thickness of a page in a textbook was measured with a micrometer to be 0.018 centimeter. The micrometer’s measurement has an uncertainty of plus or minus 0.001 centimeter
Calculation:
Since the uncertainty of the measurement is 0.001 cm ,the thickness of the page needs to be accurate to the nearest thousandth of a cm (which is 0.001 cm )
Conclusion:
0.001 cm.
c.
To state: A rule that you could use to express the thickness of the page in the most accurate terms.
