Acar is moving at constant velocity towards a brick wall.
the car collides head on with the brick wall.
use newton's laws to explain the forces acting on the car before and during the collision.

Before collision: newton's first law - since uniform motion

On collision : newton's second law - since change in momentum

Explanation:

Newton's first law states it is the inertia of the body to remain in a state of rest or in a uniform motion in straight line unless acted upon by an external force. Since, the car is under uniform speed

Newton's second law states that the force acting on a body is directly proportional to the change in momentum. Since the momentum of car changes in short interval of time.

Hence, the forces acting on the car can be explained with the help of newton's first law and newton's second law.

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

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
