Suppose you have one magnet in a straw with its South pole pointed upward. What would happen if you put another magnet into the straw with it's North pole pointed downward?
a. The magnets would be attracted to each other.
b. The magnets would become demagnetized,
c. The second magnet would be pushed out of the straw.
d. The magnets would repel each other.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

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
