A friend of yours left a pile of mail on a table. You notice your favorite magazine sticking out from under a package. You grab the magazine by its corner and get it from under the package. As you get your magazine, the package does not topple because A- it has no acceleration
B-the force of gravity keeps it secured
C-it has inertia
D- a pair of action-reaction forces act on it

d or b i think

Explanation:

i looked it up on go ogle :)

b

Explanation:

sounds like it should be right

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
