Question
Chapter 5, Problem 23A
Interpretation Introduction
Interpretation: The reason for the length of the pin in the given figure to not 2.850 needs to be explained.
Concept Introduction: Each time a measurement is performed with a tool like a ruler or a graduated cylinder, an estimate is needed. In measuring device, measurement uncertainty is the result of imprecision and uncertainty.
Expert Solution & Answer
Answer to Problem 23A
The smallest marking in the ruler is 0.1 cm. Hence, the length of the scale is not recorded as 2.850.
Explanation of Solution
The number 2.850 indicates that the scale is labeled to the nearest hundredth of a centimeter. The smallest marking in the scale is 0.1 cm. So, pin length is 2.8 cm.
