Question

what is the order of magnitude of 5 x 10^-7

Answer 1

Answer:

In order to compare the measured values of physical quantities, we make use of the idea of the order of magnitude.

The power, when the magnitude of a physical quantity is expressed in terms of the nearest power of ten, is called the order of magnitude. Instead of knowing the actual value of a physical quantity, in many cases, it is sufficient to know only the order of magnitude of that quantity. Order-of-magnitude helps us to write numbers that are too large or too small in a standard or convenient form and are commonly used by scientists, mathematicians, engineers etc.
