If the Moon takes 27.3 days to complete one 360° orbit around the Earth, how many degrees per day does the Moon mover across Earth's sky?

Moon moves across the Earth's sky per day = 13.2°

Explanation:

Given:

Moon take to complete one orbit around the earth = 27.3 days

earth orbit = 360°

We need to find the degrees per day does the Moon move across Earth's sky.

Solution:

Moon takes 27.3 days to complete one 360° orbit around the Earth.

So, the degrees per day is equal to 360° divided by moon take to complete one orbit around the earth.

\

Degree per day = 13.2°

Therefore, moon moves 13.2° across the Earth's sky each day.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
