Question

State the order of magnitude of the period of revolution of earth about the sun in seconds

Answer 1

The Time Period of the Revolution of the Earth around the sun is 365 days.

In Seconds, it is given as, 31536000 seconds.

Converting it into the scientific notations, 3.15 × 10⁷ seconds.

To convert it into the order of magnitudes, we need to see that the number is either greater than 5 or less than 5. Since, 3.15 is less than 5, we will left the powers of 10 unchanged.

∴ Order of magnitudes = 10⁷ .

Hope it helps.
