Change the numbers In standard form of the following statements (i) D

1.	Change the numbers In standard form of the following statements (i) Diameter of the thickness of human hair is 0.0002 cm approx. (ii) Charge on an electron is 0.000, 000, 000, 000, 000, 00016 coulomb. (iii) 1 Micron = 1/1000000 metre. (iv) Thickness of a paper = 0.0016 cm.
Answer» (i) 0.0002 = 2/10000 = 2/10⁴ = 2.0 x 10^-4 (ii) 0.000, 000, 000, 000, 000, 00016 = 1.6 x 10^-19 coulomb (iii) 1/1000000 = 1 x 10^-6 (iv) 0.0016 = 16/10000 = 16/10⁴ = 16 x 10^-4 = 1.6 x 10^-3cm

Answer»

(i) 0.0002

= 2/10000

= 2/10⁴

= 2.0 x 10^-4

(ii) 0.000, 000, 000, 000, 000, 00016

= 1.6 x 10^-19 coulomb

(iii) 1/1000000 = 1 x 10^-6

(iv) 0.0016 = 16/10000 = 16/10⁴

= 16 x 10^-4

= 1.6 x 10^-3cm
