Answer 2

Answer:

The order of magnitude of 3 × 10⁸ m/s is 8.

Explanation:

The order of magnitude is the power of 10 used in the scientific notation system. This system is used to represent a large numerical value or a very small numerical value. When we represent a number using the scientific notation, we are not changing the actual value, but we are only changing its form of appearance.

While calculating the power of 10 the decimal point of the main number should have only one digit to its left. ie;

3 × 10⁸ = 3.0 × 10⁸

Here the power of 10 is 8 and hence the order of magnitude is 8.
