1.	If the radius of earth is 640km what will be it\'s order of magnitude
Answer» Madarchood Teri gannd me mera loda<br>answer\xa0: 10^7 m is the order of magnitude of the radius of the earth.explanation\xa0:\xa0order of magnitude\xa0:-\xa0it is used scientific notation. if any number X in such a way that X = m × 10^n , where m belongs to\xa0\xa0then,\xa010ⁿ is known as order of magnitude.here given, earth\'s radius 6400 kmit can be written as 6400000m [ as we know, 1 km = 1000m]so, 6400 km = 6400000 mnow, 6400000m = 0.64 × 10^7 mhere you can see √10/10 ≤ 0.64 ≤ √10so, 10^7m is the order of magnitude.Thanku
