Question

Planet take 360×10⁷ s to complete one revolution around the planet having radius 7200×10³m.Find speed of revolution?​

Answer 1

Answer:

π/250m/s

Explanation:

speed of revolution means the ratio of distance travelled and time taken.

s=d/t;

distance travelled = 2*π*7200*10^3m;

(since circular orbit,distance travelled=perimeter of circle)

time taken=360*10^7s;

therefore,

speed of revolution= (2*π*7200*10^3)/(360*10^7)m/s

= π/250 m/s
