The full moon rises in the east at the time of sunset. after rising, it continuously moves to the west and is seen high in the sky close to midnight. which of these is the reason for the change of the moon’s position in the night sky?
a) the moon rotates on its axis.
b) the continuous change in the phases of the moon.
c) the moon orbits counterclockwise around the earth.
d) the earth rotates from west to east on its own axis.

Earth rotates from West to East on its own axis. As a result of this, the Moon changes its position during the night and the Moon appears to move from East to West in the sky.

Explanation:

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
