Question

an artificial satellite is moving in a circular orbit of radius 36000 kilometre calculate its speed if it takes 24 hours to revolve around the earth​

Answer 1

Answer:

Step-by-step explanation:

Time period = 24hrs

Radius = 36000 Km

T = 2πR ÷ V

V = 2πR ÷ T

  = 2 × 3.14 × 36000 / 24

 = 9420 Km /hr

= 9420*5/18 m/s

= 2616.6 m/s

Answer 2

Answer:

9420 km/hr

Step-by-step explanation:

Speed = 2xv

=72000×3.14km/24hr

=9420 km/hr
