Question

why physical quantities expressed in the order of magnitude support your answer by an example​

Answer 1

Explanation:

Physical quantities are represented in the form of scientific notation. It is of the form: a.b * 10^c

Where 'a' , 'b', 'c' are numbers from 0-9

For example, speed of light is about 300000000 m/s which is often written as 3.0 * 10^8. you can relate scientific notation with this.

So, now coming back to your question, the term 10^c is the order of magnitude.

P.S: Speed of light is actually **299,792,458 m/**
