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
Answer:
The main idea of any type of text (spoken or verbal), including a lecture, is the main, most important point the writer/speaker is making. In one text, there can be multiple main ideas. You can easily recognize the main ideas of a lecture by looking at its title and subtitles. For example, if you are listening to a lecture about the central nervous system, the main points could be the central nervous system itself and its most important parts, which will be represented by titles and subtitles.
When you're taking notes, you should write down the most important things the lecturer is saying. This includes the things that are closely related to the main ideas, such as definitions and explanations. If you are unable to write everything down (which is usually the case), you should focus on these main points and ignore the details, because it's more likely that you won't need them.
The answer from the given options is "superego".
In our psyche, our superego played the scrutinizing and the admonishing part. At the point when Marcy lied to her mom, her superego question her own profound quality due to her activities and caused a passionate pain inside Marcy's mind which have a tendency to keep her from rehashing that activity later on.

The irregular coastline has many natural harbors.
All of the given practices can be effective in minimizing group harms.
Answer: Option E
Explanation:
As mentioned in the options, a collaborative review of the ongoing research by the Institutional Review Board can be taken from time to time during the course of the research to check whether the group of human samples is facing any adverse effects of the research or not.
A chalked plan promising the disclosure of the results of the research can also help in decreasing group harm. Moreover, consultation among the parties participated in research can also reduce the risk of group harm.
