Question

plz write correct answer ...with all steps..

​

Answer 1

Answer:

11.92 hrs or approximately 12 hours

Step-by-step explanation:

time=distance/speed

distance=2*(pi)*r

speed(orbital velocity)=[G*M/r]^1/2                    r=radius of orbit

GM=g*R^2                                           R=radius of earth  

time=2*(pi)*r/[G*(4*M)/r]^1/2                                                  

      ={2*(pi)*[r]^3/2}/[4*g*R^2]^1/2

      ={2*(3.14)*(35780000+6400000)^3/2}/2*6400000*(9.8)^1/2.

Do the necessary calculations and you will get the answer.

I hope this helps you.
