Answer 1

Given that

The radius of the orbit = 42250 km

Find out

Speed if it takes 24 hours to revolve around the earth

Solution

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

Time taken for the orbit = 24 hours

Therefore, speed of the satellite = 11065.4 km.h-1

The satellite orbits the Earth at a speed of 11065.4 kilometers per hour.

hope it helps you

Answer 2

Answer:

3.07 kms-1

Explanation:

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

​  =  265464.58/

24×60×60

​

=3.07 kms
