Physics for Scientists and Engineers 3rd Edition by Randall Knight, Chapter 1 Conceptual Question 2

How many significant figures does each of the following numbers have? a) 310 b) 0.00310 c) 1.031 d) 3.10(10)^5

How many significant figures does each of the following numbers have? a)  310 b)  0.00310 c)  1.031 d)  Solution:

Part a

Zeroes before the decimal point merely locate the decimal point and are not significant. Thus, 310 has 2 significant figures. 

Part b

Trailing zeros after the decimal point are significant because they indicate increased precision. Therefore, 0.00310 has 3…
