The upward force that a fluid exerts on an object is called the buoyant force. how is the buoyant force similar to the frictional force?
a.
both buoyant and frictional forces can act over short distances.
b.
both buoyant and frictional forces do not involve solids.
c.
both buoyant and frictional forces act only with contact.
d.
both buoyant and frictional forces push objects upward.

powerful computers now, not then

probably not if net force is zero

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
