Question

If earth-moon distance is 3.8×10^5 km,calculate the time (in days) it takes the moon to circle the earth.mass of earth =5.98×10^24.

Answer 1

Hope it helps. I have only provided method, please solve it

Answer 2

Answer:

We are supposed to find velocity ..

Explanation:

R=3.8*10^5

T=27days

So .. velocity = distance/time

V= 2πR/T

=2*3.14*3.8*10^5/27

= 8.838*10^5*10^-1

=8.838*10^4 km /day
