How did ptolemy account for retrograde motion in his model of the solar system
IgorC [24]

<u>Answer:</u>

Ptolemy accounted for 'retrograde motion' in his model of the solar system by introducing smaller circles named 'epicycles'.

<u>Explanation:</u>

  • According to Ptolemy, the Sun and the other planets in the Solar system orbited around the Earth.
  • The Greeks were convinced that Ptolemy's earlier model did not provide for backward or the retrograde motion.
  • Ptolemy thought over it for a while and theorized the possibility of 'epicycles'.
  • According to Ptolemy, the planets that orbited Earth also orbited another smaller point.
  • The smaller orbits followed by the planets while in motion around the Earth in a larger orbit were introduced by Ptolemy as 'epicycles'.
  • Until Kepler proposed his models of the functioning of the Solar system, Ptolemy's models were considered the most relevant.

Describe the Greek city-states, different types of government and development of Democracy.
Ede4ka [16]

Answer:

A city-state, or polis, was the community structure of ancient Greece. Each city-state was organized with an urban center and the surrounding countryside. Characteristics of the city in a polis were outer walls for protection, as well as a public space that included temples and government buildings. The temples and government buildings were often built on the top of a hill, or acropolis. A surviving example of a structure central to an ancient acropolis is the famous Parthenon of Athens. The Parthenon was a temple built to honor the goddess Athena. The majority of a polis’s population lived in the city, as it was the center of trade, commerce, culture, and political activity.

There grew to be over 1,000 city-states in ancient Greece, but the main poleis were Athína (Athens), Spárti (Sparta), Kórinthos (Corinth), Thíva (Thebes), Siracusa (Syracuse), Égina (Aegina), Ródos (Rhodes), Árgos, Erétria, and Elis. Each city-state ruled itself. They differed greatly from the each other in governing philosophies and interests. For example, Sparta was ruled by two kings and a council of elders. It emphasized maintaining a strong military, while Athens valued education and art. In Athens every male citizen had the right to vote, so they were ruled by a democracy. Rather than have a strong army, Athens maintained their navy.

Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place. Another reason city-states formed, rather than a central, all-encompassing monarchy, was that the Greek aristocracy strove to maintain their city-states’ independence and to unseat any potential tyra

Acidic water containing chemicals and heavy metals from an abandoned coal mine has washed into a nearby river. All of the follow
Romashka [77]

Answer: An erosion of soil which enters waterways

Explanation:

Acidic water is more poisonous to human, animal and plant life so if acidic water were to wash into a river that humans drink, the health risks posed to those humans would increase.

If there were plants and animals connected to the river, the risks to them would increase as well and disrupt their life cycle.

Acidic water does not make water more or less capable of soil erosion so the water being acidic would not contribute to soil erosion.
