Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.
Aristotle from Classic Greece and Ptolemy from Roman Egypt agreed on three facts:
- Earth and other celestial bodies are spherical in shape.
- Earth is in the center and all other celestial bodies revolve around it.
- The other planets orbit in a circular path.
This model of the solar system with Earth in the center is called as Geocentric model.
Therefore, Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.

Answer:
Solid: metal alloy
Liquid: beer
Gas: Air
Explanation:
A solution is a type of mixture where the solvent and solute are homogeneously mixed. Homogeneous mixture means that the solute shouldn't be able to be seen with the naked eye, filtered and stable enough.
Metal alloy will be an example of a solution in solid-state. Beer is a solution made of liquid alcohol and liquid water. Air mostly composed of nitrogen, but it has oxygen, carbon dioxide, and many other substances in gaseous form.

nucleus that is breaking apart, it should be called as the nuclear
fusion. These things usually can be caused by the decay of the
radioactive and the nuclear reaction.
P.S
Happy to help you have an AWESOME!!! day :)
Answer: n = c / v" "c" is the speed of light in a vacuum, "v" is the speed of light in that substance and "n" is the index of refraction. According to the formula, the index of refraction is the relation between the speed of light in a vacuum and the speed of light in a substance.
Explanation: the relation is the vacuum and the speed of light in a substance.
