Concept explainers
Interpretation:
Ruler that can make more precise measurement needs to be determined.
Concept introduction:
The precision of a measurement is denoted by the number of digits reported and the reported digits are termed as significant figures. Significant figures include all known digits plus one estimated digit.
Answer to Problem 12STP
Top ruler is used to make the more precise measurement.
Explanation of Solution
Precision defined as a set of precise measurements that shows a little variation.
The given figure shows two regular rulers and one rod between rulers. The markings on the ruler represent known digits. The reported measurement includes the known digits plus the estimated digit. The top ruler has more divisions and because of this a student can read it to a more precise decimal place. Hence, top ruler makes the more precise measurement.
Top rulermakes the more precise measurement.
