When rockets split do they come back to earth?

A heavier mass m1 and a lighter mass m2 are 19.0 cm apart and experience a gravitational force of attraction that is 9.20 x 10^-9 N in magnitude. The two masses have a combined value of 5.80 kg. Determine the value of each individual mass.

The density of air under normal conditions is about 3 1.2 kg / m. For a wind speed of 10 m/s, find (a) the actual power carried in the wind; (b) the maximum power (Betz limit) extractable by a wind turbine with a blade area of 10 m2;

Do we have free will or is everything predestined?

Why does Newton's law of universal gravitation apply to all objects in the universe?

Ojectile is launched on the Earth with a certain ini - tial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one - sixth as large.
