1.	Express the following information in the standard form. (i) The size of red blood cells is 0.000007mm(ii) The speed of light is 300000000 m/sec(iii) The distance between the moon and the earth is 384467000 m(app)(iv) The charge of an electron is 0.0000000000000000016 coulombs(v) Thickness of a piece of paper is 0.0016 cm(vi) The diameter of a wire on a computer chip is 0.000005 cm
Answer» (i) The size of red blood cells is 0.000007mm = 7 / 1000000 = 7 × 10^-6 (ii) The speed of light is 300000000 m/sec = 3 × 10,00,00,000 = 3 × 10⁸ m/sec (iii) The distance between the moon and the earth is 384467000 m(app) = 384467 × 1000 m = 384467 × 10³ (iv) The charge of an electron is 0.0000000000000000016 coulombs = 0.0000000000000000016 = 16 / 10000000000000000000 = 16 / 10¹⁹ = 16 × 10^-19 coulombs (v) Thickness of a piece of paper is 0.0016 cm = 0.0016 cm = 16 / 10000 = 16 / 10⁴ = 16 × 10^-4 cm (vi) The diameter of a wire on a computer chip is 0.000005 cm = 0.000005 cm = 5 / 1000000 cm = 5 / 10⁶ cm = 5 × 10^-6 cm

Answer»

(i) The size of red blood cells is 0.000007mm

= 7 / 1000000 = 7 × 10^-6

(ii) The speed of light is 300000000 m/sec

= 3 × 10,00,00,000 = 3 × 10⁸ m/sec

(iii) The distance between the moon and the earth is 384467000 m(app)

= 384467 × 1000 m

= 384467 × 10³

(iv) The charge of an electron is 0.0000000000000000016 coulombs

= 0.0000000000000000016

= 16 / 10000000000000000000

= 16 / 10¹⁹

= 16 × 10^-19 coulombs

(v) Thickness of a piece of paper is 0.0016 cm

= 0.0016 cm = 16 / 10000

= 16 / 10⁴

= 16 × 10^-4 cm

(vi) The diameter of a wire on a computer chip is 0.000005 cm

= 0.000005 cm = 5 / 1000000 cm

= 5 / 10⁶ cm = 5 × 10^-6 cm
