Calculate the force between one object with a radius of 0.08 meters and a mass of 0.045 kilograms and the earth

The force between an object with a mass and the earth is actually the weight of the object, which can be calculated by w=mg. (where w is the weight (gravity force) of the object, m is the mass of the object, and g is acceleration due to gravity.)

So, w = 0.045 kg x 9.8 m/s2

         = 0.441 N (Newton)

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
