Question

 An artificial satellite is moving in a circular orbit of radius 42250 km .Calculate its speed

If its take 24 hrs to revolve around the earth?

​

Answer 1

Answer:

11065.47 km/h

Explanation:

Radius=42250 km

Time taken to receive around the earth=24 hour

We know that,

$speed = distance \: travelled \div time \: taken$

Distance travelled by the satellite in 1 revolution around the earth=

$2\pi \: r$

$2 \times 22/7 \times 42250$

$265571.23$

Time taken=24 hour

$265571.43 \div 24$

$11065.47$
