Homework Answers
1.
Retrograde motion: westward motion of the planets relative to the stars.
Correct option is D.
2.
Correct option is D. Ptolemaic model. In this model Earth was fixed
Copernican model: In this model Sun was fixed
Tychonic model: In this model all the planet except earth moves around Sun and Sun moves around Earth.
Keplerian Model: In this model all the planets goes around fixed Sun.

The Apparent Motion of the Surn The sun rises in the east, moves across the south, and sets in the west much as stars in non-circumpolar constellations do. Just as for the stars, this apparent motion is really due to the rotation of the earth on its axis The Earth's motion around the Sun adds a complication to the Sun's apparent motion. In a full year, or 365 days, the Earth would go completely around the Sun so that the...

1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...

1.2 Models of Reality Where does the Sun go? At a very young age, infants learn to go from simple observations to mental models of what they are observing. The simplest sort of model is called "object permanence" and just means that something can be hidden or out of sight and still exist. urement? In the case of the Sun rising and setting, this model suggests that it is always the same Sun, which means that the Sun must somehow...
