Express the following quantities using prefixes.
(a) 5000 g (b) 2000000 W
(c) 52 x10⁻¹⁰ kg (d) 225x10⁻⁸ s
Ans. {(a) 5 kg (b)2 MW (c) 5.2 µg (d) 2.25 µs }
Solution:
⟹ 5 x 1000 g
⟹ 5 x 10³ g [∴ 10³ = k]
⟹ 5 kg
(b) 2000,000 W
⟹ 2 x 1000,000 W
⟹ 2 x 10⁶ W [∴ 10⁶ = M]
⟹ 2 MW ------------Ans.
(c) 52 x 10⁻¹⁰ Kg
⟹ 5.2 x10 x10⁻¹⁰ x 10³ g [∴ 10³ = k]
⟹ 5.2 x10 x10⁻¹⁰ x 10³ g
⟹ 5.2 x 10¹⁻¹⁰⁺³ g
⟹ 5.2 x10⁻⁶ g [∴ 10⁻⁶ = µ]
⟹ 5.2 µg -------------Ans.
(d) 225 x 10⁻⁸ s
⟹ 2.25 x10² x10⁻⁸ s
⟹ 5.2 x 10²⁻⁸ s
⟹ 5.2 x10⁻⁶ s [∴ 10⁻⁶ = µ]
⟹ 5.2 µs ----------Ans.
