The loops in ptolemy’s heliocentric model , and those shown on the video , are called?

Retrograde Motion

Explanation:

The theory that the earth revolves around the Sun is called the heliocentric theory, helio meaning 'sun' and centric meaning 'in the center.

' This theory was developed in parts by different astronomers over many years, namely Aristarchus, Copernicus, Kepler, and Galileo.

The reaction from society at the time was that the heliocentric theory was not even worth talking about.

Everyone had evidence to prove that the Earth was the center because if the sun started at one point in the morning and ended at another at night, it was common sense that we were obviously the center.

Copernicus heliocentric theory or it is also named as Sun-centred theory had accepted by Galileo.

The geocentric model is also known as geocentrism.  

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
