Question

the order of magnitude of a physical quantity equal to 3.0*10^5 m is​

Answer 1

Answer:

5

Explanation:

(a+b^n)

Here the value of n is the order of magnitude.

And also the value of a<5 so the value of b is not

is not increased by 1

So, The order of magnitude is 5

Answer 2

5 is the order of magnitude of a physical quantity equal to 3.0 × 10⁵

Order of magnitude is the exponential value or the power of a value raised to 10. The number is standardized by adding decimal point after first digit from left and assigning relevant power to 10 which is multiplied to the number. This power is the order of that number .

Order of magnitude is relevant when we are not interested in the exact value to every decimal or when the number is large minute. The size of a number can be approximated with reference to its power.

3.0 × 10⁵ has the power 5 and hence it is the numbers order.
