Ballistics is a kind of science study that deals with Rocket launching Speed.
If a Airplane goes at 1000 mile/hr then we can not able to hear the sound of the plane
because the speed of plane is more than the air.
The distance between moon and earth is 3,82,176 km.
The diameter of earth = The diameter of moon x 4
