Question

the mass of a dust particle is 0.000000000735 kilograms. What is the mass written in scientific notation?

Answer 1

0.000000000735 = 7.35 x 10^-10 kg

Answer 2

Option D -
`7.35* 10^(-10)`

Explanation:

Given : The mass of a dust particle is 0.000000000735 kilograms.

To find : What is the mass written in scientific notation?

Solution :

Scientific notation is writing a number into smaller or larger number.

Mostly scientific number is in a number before decimal and then the multiple of 10 to the powers.

So,
`0.000000000735=(735)/(1000000000000)`

`0.000000000735=7.35* 10^(-10)`

The mass in scientific notation is
`0.000000000735=7.35* 10^(-10)` kg.

Therefore, Option D is correct.
