Answer» ime TAKEN by satellite to complete one revolution around Earth = 48 hours Velocity of Satellite = 1500 km/hTo Find:The Radius of orbit in which the satellite is revolving around the Earth Solution:Distance covered by satellite in one revolution can be OBTAINED by USING Distance = Speed x Time Distance = (1500 km/h) x (48 hours) Distance = 72000 km --------------- ( 1 ) We know that CIRCUMFERENCE of orbit = Distance covered by satellite -----------( 2 ) Using equation (1) in equation (2) Circumference = 72000r = 11454. 5 kmHence the Radius of orbit in which the satellite is revolving is APPROXIMATELY equal to 11455 km. |
