Question

An artificial satellite is moving in a circular orbit of radius 4200 kilometers around the earth. What is it's speed if it takes one day to complete one revolution​

Answer 1

Answer:

Explanation:

Distance covered by the satellite in 24 hours

Distance covered by the satellite in 24 hours s=2πr

=2×3.14×42250=265464.58 km

=2×3.14×42250=265464.58 km Therefore speed of satellite,

=2×3.14×42250=265464.58 km Therefore speed of satellite,

v= time taken distance travelled

distance travelled = 24×60×60

distance travelled = 24×60×60265464.58

distance travelled = 24×60×60265464.58

distance travelled = 24×60×60265464.58 =3.07 km s^−1
