the distance 9460528100000000 km.​

Answer 1

Step-by-step explanation:

Given that:

(1) The world population is nearly 7000,000,000

(2) One light year means the distance 9460528100000000 km.

(3) Mass of an electron is

0.000 000 000 000 000 000 000 000 000 00091002

To find: Represent the following information in scientific notation.

Solution:In scientific notation a decimal number is expressed in the form of Exponent.

(1) The world population is nearly 7000,000,000

Ans: Scientific notation

$\bold{7 \times {10}^{9}}$

(2) One light year means the distance

9460528100000000 km

$\bold{9.46 \times {10}^{15} km}$

3) Mass of an electron

0.000 000 000 000 000 000 000 000 000 00091002

$\bold{ 9.1002</p><p>\times {10}^{ - 31} \: kg}$
