Answer:
The planet will move from east to west for a couple of months in the night sky.
Explanation:
Retrograde motion is an optical effect due to the fact that Earth rotates more quickly than the planet that apparently has a retrograde motion in the sky.
For example, Saturn has a slower speed in its orbit around the Sun. That means that the Earth will pass it, and that will give the effect that the planet is moving backward. That same scenario can be seen between two cars on a highway, the faster car will see the slower car when it passes as it is moving for a short fragment of time in backward.
Remember that the planets in the night sky move from west to east, in the case of a planet with retrograde motion, it will move from east to west for a couple of months.

Which explanations provide support for continental drift theory? Check all that apply.
Dinosaurs lived on many continents.
Coal fields match up across continents.
Tropical plant fossils were found in Arctic areas.
Similar rock types are found across continents.
Evidence of glaciers can be found in South Africa.

<h3><u>
Explanation:</u></h3>
The way the continents on the earth shifts its position is explained by the Continental drift theory. Alfred Wegener was the one who fist proposed this theory in 1912. This theory also explains how similar rocks are formed on the different continents and also the reason why some of the animal and plant fossils looks similar.
The evidences that supports the continental drift theory can be Coal fields match up across continents. Fossils of Glossopteris supports the theory of continental drift with coal fields and coastlines
. The land features, climate changes are some of the evidences that also supports the theory of continental drift.The evidences of the glaciers that can be found in South Africa also supports the explanation of the continental drift.
Answer:
Emechanical=mgh+
mν²
Explanation:
The equation for the total mechanical energy is:
Emechanical=Epotential+Ekinetic
In which,
Epotential=mgh; m: mass of the body, g: gravity; h: height
Ekinetic=mν²; m: mass of the body, ν: velocity of the body
So,
Emechanical=mgh+mν²
Zoroastrianism affected the way the Persians governed their subjects by allowing the territories under their rule to worship their own religion.
