Answer 1

Answer:

3 , 4, 9, 21, 33

Explanation:

Answer 2

Answer:

(I). 1

(II). 4

(III). 2

(IV). 2

(V). 2

Explanation:

We need to calculate the number of significant figure,

The number of significant given by,

(I). 0.003 m²

The number of significant figure is 1.

(II). 0.1250 gm cm⁻²

The  number of significant figure is 4.

(III). $6.4\times10^{-6}\ m$

The number of significant figure is 2.

(IV). $1.6\times10^{-19}\ c$

The number of significant figure is 2.

(V). $9.1\times10^{-31}\ kg$

The number of significant figure is 2.

Hence, This is the required solution.
