A wagon has a mass of 100 grams and an
acceleration of 2m/s/s. What is the force on the
wagon?

0.2N

Explanation:

mass of wagon = 100 grams

Convert mass in grams to kilograms

If 1000 grams = 1kg

100 grams = (100/1000) = 0.1kg

Acceleration of wagon = 2m/s/s

Force on the wagon = ?

Recall that Force is the product of mass of an object by the acceleration by which it moves.

i.e Force = mass x acceleration

Force = 0.1kg x 2m/s/s

Force = 0.2N

Thus, the force on the wagon is 0.2Newton

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

i think its c if i'm wrong
