Question

Write down the number of significant figures in the following 0.003m2,0.1250gm cm-2, 6.4*10^6m,1.5*10^-19c, 9.1*10-31kg​

Answer 1

Answer:

The term significant figures refers to the number of important single digits (0 through 9 inclusive) in the coefficient of an expression in scientific notation . The number of significant figures in an expression indicates the confidence or precision with which an engineer or scientist states a quantity.

Answer 2

Explanation:

Significant number :

A number's significant figures are digits that carry meaning that relate to its resolution of measurement. All numbers are included except: all leading zeros.

We need to calculate the number of significant

0.003 m² = the number of significant is 1.

0.1250 gm c/m² = the number of significant is 3.

$6.4\times10^{6}$ = the number of significant is 2.

$1.5\times10^{-19}$ = the number of significant is 2.

$9.1\times10^{-3}$ = the number of significant is 2.

Hence, This is the required solution.
