Answer:
The options.
A) Planet B has an orbital period 64 times shorter than Planet A.
B) Planet B has an orbital period 4 times shorter than Planet A.
C) Planet B has an orbital period 64 times longer than Planet A.
D) Planet B has an orbital period 4 times longer than Planet A.
E) Planet B has an orbital period 8 times longer than Planet A.
The CORRECT ANSWER IS E)
E) Planet B has an orbital period 8 times longer than Planet A.
Explanation:
Using P2 = a3 to do the estimation.
Let the size of the orbit (a) be represented in astronomical units (1 AU is the average distance between the Earth and Sun) and the period (P) is estimated in years, then Kepler's Third Law says P2 = a3.
It implies that:
A) the period of a planet is independent on its mass.
B) all orbits that possess equal semimajor axis possesses equal period.
C) planets that very distant from the Sun moves slowly than those that are nearer to the sun.
P2 = a3
Given, a =2
P2 = (2)^3
P2 = 8
E) Planet B has an orbital period 8 times longer than Planet A
As a peninsula, the people of Greece took advantage of living by the sea. The mountains in Greece did not have fertile soil good for growing crops, like in Mesopotamia, but the mild climate allowed for some farming. The Greeks, like many other ancient civilizations, felt deeply connected to the land they lived on.
The Homestead Act made it possible for millions of people to achieve the dream of owning a house. It made it possible for people to become landowners at little or no cost. This was due to the fact that there was a lot of land which was unaccounted for and many leaders wanted people to own land without owning slaves. The requirements were easy: residency in the United States, 21 and up or head of a family and anyone who had never taken up arms against the United States.
