Question

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

Answer 1

$\huge \fbox \blue{Answer:}$

Distance Covered by the Satellite in 24 hours.

$\fbox{S = 2πr}$

$= 2 \times 3.14 \times 42250$

$= 265464.58 \: km$

Therefore Speed of Satellite,

$⇒V = \frac{Distance \: Travelled }{Time \: Taken}$

$= \frac{265464.58}{24 \times 60 \times 60}$

$= 3.07 \: km \: {s}^{ - 1}$

Answer 2

Given, Radius of the circular orbit =

Circumference of the orbit =

The satellite takes 24 hours to revolve around the earth.

We know,
