Question

20. An artificial satellite is moving in a circular orbit of radius 42.250 km (approx). Calculate its linear
velocity if takes 24 hours to revolve around the earth.

Answer 1

Answer: Hey buddy here's ur answer !!

First of all it should be 42250km no decimals are there, u can check the question !!

Step-by-step explanation: As we know circumference of a circle is 2πr.

Therefore, Circumference of the circular orbit = 2×22/7×42250

= 265330.42 km/h

Since, we all know that it is taking 24 hrs to revolve around the circular orbit,

V=S/T

= V=265330.52/24×60×60

= V= 3.07 km/s.

Therefore the linear velocity of the satellite is 3.07 km/s.

Hope it helps

Warm regards !
