Answer:
a round shape. It has its own gravity to pull itself into a round shape
The radius of Earth's circular trajectory is

The time for the Earth to travel around the Sun is

Thus the velocity is velocity

From this we can deduce the centripetal acceleration

Angular velocity is
Answer:
Answer: Say the big boy is 40kg and the small boy is 20kg... ... ...then by the rule that moments around a fulcrum or pivot should be equal for equilibrium, the distance of big boy from pivot=half of dist of small boy from pivot
