which change will always result in an increase in the gravitational force between two objects?\nincreasing…

Explanation:

Step1: Recall gravitational - force formula

The gravitational force formula is $F = G\frac{m_1m_2}{r^2}$, where $F$ is the gravitational force, $G$ is the gravitational constant, $m_1$ and $m_2$ are the masses of the two objects, and $r$ is the distance between the centers of the two objects.

Step2: Analyze the effect of mass and distance on force

From the formula, $F$ is directly proportional to the product of the masses $m_1m_2$ (i.e., when $m_1$ and $m_2$ increase, $F$ increases) and inversely proportional to the square of the distance $r^2$ (i.e., when $r$ decreases, $F$ increases).

Answer:

C. increasing the masses of the objects and decreasing the distance between the objects
