Answer:
A. The movement of the Earth along its orbit
Explanation:
The moon orbits the Earth once every 27.3 days. This is the sidereal month. It is measured against the background stars.
However, the Earth is also orbiting the Sun, and the moon needs extra time to catch up to its previous position relative to the Sun. This is the synodic month. It takes 29.5 days.
B is wrong. The rotational speed of the Earth constant. It makes one revolution every 23 h 56 min 4.09053 s.
C is wrong. The synchronous rotation of the moon does not affect its orbital speed.
D is wrong. The tilt of the Earth's axis affects only the moon's angle in the sky.
Answer:
1. c. eccentric epicycles
2. d. The oceans sit on the Earth without falling over the edge.
Explanation:
1.
In Ptolemaic model is used to study the apparent motion of planets in direct way , by assuming that each and every planet moves on a small sphere or circle , known as the epicycle . And each planet is moved by a system of two spheres one is epicylce and other is different , the center of different circle is called eccentrics . Nested spheres are also present in the Ptolemy's model.
2.
The oceans sit on the Earth without falling over the edge is the correct answer. If all the heavy density objects are pushing lighter objects away then the Earth itself would have thrown away the oceans out of its reach.
I believe it is B hope this helps and have a great day :-)
