Answer:
<u>Geocentric Model</u>: - this model is Earth Centered
-Retrograde motion is explained by epicycles
<u>Heliocentric Model</u>: - This model is Sun Centered
-Retrograde motion is explained by the orbital speeds of planets
<u>Both models</u>:- Epicycles and deferents help explain planetary motion
-Planets move in circular orbits and with uniform motion
-The brightness of a planet increases when the planet is closest to Earth
Explanation:
Retrograde motion is an apparent change in the movement of the planet through the sky. Ptolemy's model of the solar systems was geocentric, where the Sun, Moon, planets and start all orbit the Earth in perfectly circular orbits. However this perfectly circular orbits around the Earth did not explain the occasional retrograde motion of the planets. In the Copernicus' heliocentric model, retrograde motion of planets is naturally explained. The explanation for retrograde motion in a heliocentric model is that retrograde occurs roughly when a faster moving planet catches up to and passes a slower moving planet.
The correct answer is A. Desalination is the process used in countries with arid climates. Desalination is used as a water purifying step in these regions since in countries with arid climates have scarcity of fresh water sources.
Answer:
A. A2. 10:00 p.m
B. B1. 7:00 a.m
C. C1. 4:00 a.m.
Explanation:
A. Time zone of Bay of Fundy is currently -3 GMT while that of Sydney is +11 GMT.
This means that Bay of Fundy is:
= 11 - (-3)
= 14 hours behind Sydney.
8 am in Bay of Fundi is:
= 8 + 14
= 22:00
= 10 pm in Sydney
B. Chicago is at -5 GMT and Hong Kong is at +8 GMT.
Chicago is:
= 8 - (-5)
= 8 + 5
= 13 hours behind Hong Kong.
8pm in Hong Kong is:
= 20:00 - 13 hours
= 0700
= 7 am in Chicago
C. Los Angeles is at -7 GMT and Moscow is at +3 GMT.
Moscow is:
= 3 - (-7)
= 10 hours ahead of Los Angeles
3 pm in Moscow is:
= 15:00 - 10 hours
= 0500
= 5 am in Los Angeles
This is probably different from options due to Daylight saving time. Pick closest option which is 4am.
Answer: A- It is a high tide somewhere on Earth constantly
Explanation:
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
Explanation:
density is in fact commonly expressed in units of grams per cubic centimetre. well think about it if we all were just a bunch of density how would it effect our health and society? well let me explain, density is also something in grams or per cubic, density can have good effects and bad effects, im not really sure the answer im trying to help but if i must say if density had a good effect there wouldn't need any worries but density can have bad side effects to everything
hope that kinda helped for ur answer...?…
