Answer:
Planet C
Explanation:
The figure of the problem is missing: find it in attachment.
The magnitude of the gravitational force between two objects is given by the equation:
where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between the objects
In this problem, we have four planets around planet X, and the mass of each planet is proportional to its size in the figure.
As we can see from the previous equation, the magnitude of the gravitational force is proportional to the mass of the planets: therefore, the planet with largest mass will exert the largest gravitational force on planet X.
From the figure, we see that planet C has the largest size, so the largest mass: therefore, planet C exerts the greatest gravitational force on planet X.

Explanation:
The given equation is where
denotes initial time in the stopwatch and
denotes the distance covered by car.
As the judge starts her watch at the instant the car passes the 2.0 meter mark and the judge reads 3.9 seconds on her stopwatch when the car passes the 8.0 meter mark.
