2. _Which one of the following is the greatest mass? (Hint: converting all
masses to the same unit may help you solve this problem.)
а. 2.0 х 105 сg
b. 10.0 g
c. 0.0010 kg
d. 1.0 x 106 mg
е. 3.0 х 10? mg

Expert Solution

Step 1

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).

Step 2

2. In order to compare any quantity , it unit should be made similar . For given masses in given unit , we need to convert all in gram in order to compare .

a) $2 \times 10^{5} c g$ :

$1 c g = 10^{- 2} g 2 \times 10^{5} c g = 2 \times 10^{3} g$

b) $10 g$

c) $0.0010 k g$

$1 k g = 10^{3} g 0.001 k g = 1 g$

d) $1 \times 10^{6} m g$

$1 m g = 10^{- 3} g 1 \times 10^{6} m g = 10^{3} g$

e) $3 \times 10^{2} m g$

$1 m g = 10^{- 3} g 3 \times 10^{2} m g = 0.3 g$
