Answer:
Option D - [tex]7.35\times 10^{-10}[/tex]
Step-by-step 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, [tex]0.000000000735=\frac{735}{1000000000000}[/tex]
[tex]0.000000000735=7.35\times 10^{-10}[/tex]
The mass in scientific notation is [tex]0.000000000735=7.35\times 10^{-10}[/tex] kg.
Therefore, Option D is correct.
