Consider again the set of observations from Part A. This time, classify each observation according to whether it is consistent with only the Earth-centered model, only the Sun-centered model, both models, or neither model. (Note that an observation is "consistent" with a model if that model offers a simple explanation for the observation.)
(1) Mercury goes through a full cycle of phases.
(2) Moon rises in east, sets in west.
(3) stars circle daily around north or south celestial pole.
(4) positions of nearby stars shift slightly back & forth each year.
(5) a distant galaxy rises in east, sets in west each day.
(6) a planet beyond Saturn rises in west, sets in east.
(7) we sometimes see a crescent Jupiter.

1. Sun-centered.

2.Both models.

3. Both models.

4. Sun-centered.

5.Both models.

6. Earth-centered only

7. Neither models.

Explanation:

Mercury goes through a full cycle phase. This is not sun-centered because the earth rotes from west to east,therefore objects in the sky moves east to west.

We sometimes see a crescent in Jupiter . These models cannot classify the observation because for an object to be seen as a crescent,the object must come between the earth and the sun.

Observation 3 and 5 can be classified with both models because the rise and set of all objects in the sky depend only on the rotation of the earth.

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)
