1.	Express the number appearing in the following statements in standard form.(i) 1 micron is equal to 1/1000000 m.(ii) Charge of an electron is 0.000, 000, 000, 000, 000, 000, 16 coulomb.(iii) Size of a bacteria is 0.0000005 m(iv) Size of a plant cell is 0.00001275 m(v) Thickness of a thick paper is 0.07 mm
Answer» (i) 1/1000000 - 1 x 10^-6 (ii) 0.000, 000, 000, 000, 000, 000, 16 = 1.6 × 10⁻¹⁹ (iii) 0.0000005 = 5 × 10⁻⁷ (iv) 0.00001275 = 1.275 × 10⁻⁵ (v) 0.07 = 7 × 10⁻²

Express the number appearing in the following statements in standard form.(i) 1 micron is equal to 1/1000000 m.(ii) Charge of an electron is 0.000, 000, 000, 000, 000, 000, 16 coulomb.(iii) Size of a bacteria is 0.0000005 m(iv) Size of a plant cell is 0.00001275 m(v) Thickness of a thick paper is 0.07 mm

Answer»

(i) 1/1000000 - 1 x 10^-6

(ii) 0.000, 000, 000, 000, 000, 000, 16 = 1.6 × 10⁻¹⁹

(iii) 0.0000005 = 5 × 10⁻⁷

(iv) 0.00001275 = 1.275 × 10⁻⁵

(v) 0.07 = 7 × 10⁻²
