two airplanes are flying in the sky in such a way that the gravitational attractions between them decreases. the planes must be flying:
away from each other
next to each other at the same speed
towards each other
faster than the speed of sound

Explanation:

According to Newton's law of universal gravitation, the gravitational force \(F = G\frac{m_1m_2}{r^2}\), where \(G\) is the gravitational constant, \(m_1\) and \(m_2\) are the masses of the two objects, and \(r\) is the distance between them. So the gravitational attraction depends on the distance and masses. For the second question, since \(F = G\frac{m_1m_2}{r^2}\), when \(r\) (the distance between the two airplanes) increases (planes fly away from each other), \(F\) (gravitational attraction) decreases.

Answer:

First question: masses. Second question: away from each other.
