Question

An artificial satellite is moving in a circular orbit of radius 42000 km. Calculate it's velocity of takes 24 hours to revolve round the earth? Please koi jaldi btao​

Answer 1

Answer:

The orbit has a radius of 42000 km

Explanation:

So to find the circumference let us use 2 pi r

2 × 22/7 × 42000= 264000

So we should do 264000 ÷ 24 = 11000

Answer 2

Answer:

the velocity of the satellite is 11000km/h

Explanation:

we know that the velocity is defined as the displacement over time taken

thus here the displacement is the circumference of the circle

I.e. 2 * pi * r

2 * 22/7 * 42000 =. 264000

the time given is 24 h

thus velocity is

v = 264000 / 24

v = 11000 km/h
