Which of the following correctly compares gravitational force and distance between two objects?

as the distance increases, the gravitational force increases.
as the distance increases, the gravitational force decreases.
as the distance decreases, the gravitational force decreases.
there is no relationship between gravitational force and distance between two objects.

The mass of the object must be determined

The distance between the two objects is measured

Equation must be solved: All units must be expressed by the metric system and on the corresponding scale

Explanation:

To find the gravitational force you must follow a procedure, it has the following steps:

The equation must be defined for the force of gravity to find the gravity of the object: To find the gravity of two objects that are far away you must take into account the masses of the objects

Formula: Fgrav(Gm1, m2)/d2

f: strength

G: constant of universal gravitation

M1: mass of the first object

M2: mass of the second object

D: distance between objects

Metric distances should be used: the masses of the objects must be expressed in Kg( kilograms) and the distance in M (meters)

The mass of the object must be determined

The distance between the two objects is measured

Equation must be solved: All units must be expressed by the metric system and on the corresponding scale

Explanation:

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
