Question

a satellite is moving in a circular orbit of radius 7200 km and takes 2 hours to revolve around the sun calculate the speed of the satellite ​

Answer 1

Explanation:

r=7200km

time taken by the satellite is 2 hrs

:. speed = distance /time

=7200/2

=3200km/h

the speed of satellite is 3200km/h

hope so this is right and can help u

Answer 2

Circumference of the orbit = 2*$\pi$*(radius of the orbit)

= 2*3.14*7200

= 45216 km

Speed of the satellite = (distance covered by the satellite) / (time taken by the satellite to cover this distance)

= 45216 / 2

= 22608 kmph
