Question

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

Answer 1

AS RADIUS OF ORBIT IT'S 42250KM

SO DIAMETER=2R

D=2×42250KM

D=84500KM

AS
SPEED=DISTANCE/TIME

SPEED=D/T

SPEED=84500/24

SPEED =3380KM/HR

SPEED =3380×1000/3600

speed =430m/sec

hope it will help u
