Increase

Explanation:

A force that acts on an object causes the object to accelerate.

F=ma

When mass is kept constant, force is directly proportional to the acceleration. Meaning that if the force increases, the acceleration increases, and if force decreases the acceleration decreases.

When force is kept constant, acceleration is inversely proportional to mass.

Meaning that when the mass of the objet increases, the acceleration of the object will decrease, and if the mass of the object decreases, the acceleration will increase.

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
