According to Newton's law of gravity, the Moon's gravitational pull produces how many tidal bulges (and thus high tides) on Earth at any given time?

According to Newton's law of gravity, the Moon's gravitational pull produces how many high tides (tidal bulges) on Earth in approximately 24 hours?

Which statement best explains how Newton's law of universal gravitation shows that gravity is universal in nature?

In Newton's law of universal gravitation, if the distance between two point masses is doubled while the masses remain the same, how does the gravitational force change?

In Newton's law of universal gravitation, how does the magnitude of the gravitational force between two point masses change when the distance between them is doubled (masses unchanged)?

In Newton's law of universal gravitation, $F=G\frac{m_1{m}_2}{r^2}$, how does increasing the masses affect the gravitational force between two objects if the distance $r$ remains constant?

In Newton's law of universal gravitation, what two factors determine the magnitude of the gravitational force between two point masses?

In Newton's law of universal gravitation, the magnitude of the gravitational force between two point masses depends on which two factors?
