It is given that

The radius of circular orbit r = 42250 km

The time period of satellite T = 24 hours

Distance traveled by satellite to complete 1 revolution = Circumference of a circle

S = 2πr

Substituting the values

S = 2 x 3.14 x 42250 = 265464.58 km

When the distance D and time T are given, speed v can be calculated using

v = D/T

Substituting the values

v = 265464.58/(24 x 60 x 60)

v = 3.07 km/s

Therefore, the speed is 3.07 km/s.

Summary:

An artificial satellite is moving in a circular orbit with a radius of 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth.

An artificial satellite is moving in a circular orbit with a radius of 42250 km. Its speed is 3.07 km/s if it takes 24 hours to revolve around the earth.
