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:
Quantitative research is statistical: it has numbers attached to it, like averages, percentages or quotas. Qualitative research uses non-statistical methods. For example, you might perform a study and find that 50% of a district’s students dislike their teachers.
Explanation:
Characteristics of Qualitative Research.
Findings are judged by whether they make sense and are consistent with the collected data.
Results are validated externally by how well they might be applicable to other situations. This is tough to do; rich, detailed descriptions can help to bolster external validity.
Data is usually collected from small, specific and non-random samples.
Actions of the researcher that can compromise the integrity of the findings:
Intellectual honesty in proposing, performing, and reporting research refers to honesty with respect to the meaning of one's research. It is expected that researchers present proposals and data honestly and communicate their best understanding of the work in writing and verbally.
When a researcher do not exemplify and transmit the values associated with ethical scientific conduct” (NAS, 1995, preface).
