Answer 1

Here is the answer in the attached picture!!!!

Answer 2

Given, the radius of the orbit, r = 42250 km

The circumference of orbit = 2πr

speed of the artificial satellite = 2π(42250) / 24

= 2(3.14)(42250) / 24 = 11055.41 km/hr

Thus, the speed of the artificial satellite is 11055.41 kilometres per hour.

Hope it helps!!
