km. Calculate its speed if it takes 24 hrs to revolve around
the earth.
Long Answer give answer fast​

Answer 1

Answer:

Hope this may help you

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

=

24×60×60

265464.58

=3.07 km s raise to-1

Answer 2

Answer:

speed=4000km/hr

Explanation:

we know that,

speed=distance/Time

speed=48000/24[since,distance=48000and time=24]

speed=2000 km/hr

now,

speed to revolve around earth =2×2000

=4000km/hr[as diameter=2radius]
