Question

an Indian satellite is moving in a circular orbit of radius 48000 km. Calculate speed if it takes 24 hrs to revolve around the earth.​

Answer 1

Answer:

SOLUTION

Explanation:

Correct option is

A

3.07 kms

−1

Distance covered by the satellite in 24 hours

s=2πr

=2×3.14×42250=265464.58 km

Therefore speed of satellite,

v=

time taken

distance travelled

=

24×60×60

265464.58

=3.07 km s

−1

Answer 2

$\huge{\mathcal {\purple {A}\green {n}\pink {s}\blue {w}\purple{e}\green {r}}}$

Therefore, circumference of the orbit = 2*π*42250km = 265571.42

kmTime taken for the orbit = 24

hoursTherefore, speed of the satellite = 11065.4 km.h-1The satellite orbits the

Earth at a speed of 11065.4 kilometers per hour.
