Question

0 Hoy many numbers of significant figures are in 0.007 m²
(A) 4 (B) 3 (C) 2
(D) )​

Answer 1

Answer:

Good Morning mate......

Explanation:

The given quantity is 0.007 m2. If the number is less than one, then all zeros on the right of the decimal point (but left to the first non-zero) are insignificant. This means that here, two zeros after the decimal are not significant. Hence, only 7 is a significant figure in this quantity.

Answer 2

The number of significant figures in 0.007m² is one.

• While significant figures are noted, if the number of values is less than one, then all zeros on the right side of the decimal point become insignificant.

• The zeroes must be on the right side of the decimal point but left to the first non-zero point.

• Thus, in the given value of 0.007 there are two zeros after the decimal and are not significant. Only 7 is a significant figure. Thus there is only one significant value.
