Question
Why did Aristotle think the planets moved in circles? Circular movement is more sacred and thus most suitable for gods. Circular movement starts over after arriving back at its starting point. Circular movement conforms to the circular shape of the cosmos. Circular movement accounted for all observations up to his time. Why was the heliocentric model of Aristarchos of Samos rejected? It was blasphemous to remove the Earth from the center of the cosmos. If the Earth was moving the wind should scour it smooth. If the Earth was moving the stars should seem to shift. b and c. According to the theory of natural place, why does steam rise and rain fall? Steam has lower density than air and rain has higher density than air. Steam and rain each seek their natural distance from the center of the cosmos. Hot substances belong at higher altitudes and cool things at lower altitudes. Steam is attracted by clouds and rain by the sea. Which of these things did Eratosthenes calculate? The distance from Alexandria to Syrene. The diameter of the Earth. The size of the Sun. The distance from Earth to the Sun.Explanation / Answer
4) Eratosthenes was a mathematician and geographist. He was known for some works like. He was the first who calculated the circumference of the Earth and distance from Earth to the sun.. The correct option are options (b) & (d)..!!
3) The correct option is option (a) steam is warmer in nature due to which it is less dense than air. Hence rises up. But in the case of rain it is heavier than air hence it comes down back to the ground..!!
1) the correct option is option (c) I.e the circular movement can be said due to the spherical shape of the planets which results in the circular force towards inside resulting in circular motion..!!
