Concept explainers
(a)
Interpretation: The significant figure needs to be determined.
Concept Introduction: Measurement lies at the heart of doing science. Any measurement involves an estimate and thus is uncertain to some extent. A reliably identified digits used to find a decimal point is known as significant figure.
(a)
Answer to Problem 7RQ
The answer is
Explanation of Solution
The number of meaningful digits in a calculated quantity is known as significant figures. All non- zero digits are significant and leading zeros are never count as significant but captive zeros are significant.
In the given figure, ruler has measurement of
