Answer 2

The Significant figure

The significant figures express the accuracy with which a physical quantity may be | expressed . " The digits , whose values are accurately known in a particular measurement , are called its significant figures . " The following rules have been set up for determining the number of significant figures.

1 . All non - zero digits are significant . 67246 have five significant figures .

2 . All zeros 0CCurring between two non - zero digits are significant . The measurement or data 209 . 005 contains six significant figures .

3 . All zeros to the right of a decimal point and to the left of a non - zero digit are never significant . The measurement 0 . 00856 contains three significant figures . The single zero conventionally placed to the left of the decimal point in such an expression is also never significant . ।

4 . ( a ) All zeros to the right of a decimal point are significant , if they are not followed by a non - zero digit , The measurement 50 . 00 contains four significant figures .

( b ) All zeros to the right of the last non - zero , digit after the decimal point are significant , The measurement 0 . 09800 Contains four significant figures .

5 . ( a ) All zeros to the right of the last ( right most ) non - zero digit are not significant . The measurement 3030 contains three significant figures .

( b ) All zeros to the right of the last non - zero digit are significant , if they come from a measurement .
