One advantage of using primary sources when doing research on an experiment is, it contain more details about the experiment. Thus, option D is right .
To find the answer, we have to know more about the Primary sources.
<h3>
What is the advantages of primary sources?</h3>
- Primary sources are the direct or first-hand excerpts that scientists have independently written based on their experiments in order to support their research.
- Utilizing original sources encourages analytical and critical thought in relation to the research.
- It aids in exploring from various angles, which leads to the discovery of extra facts.
- Primary data aids in navigating the conflicts. Since it is a direct resource related to the experiment, it serves as evidence for the data.
Thus, we can conclude that, Primary sources contain more details about the experiment.

Answer:
The wave is traveling in the +x direction.
Explanation:
The equation of a wave is given by the formula as :

Here,
A is the amplitude of wave
is the phase of wave
is the angular frequency of the wave
We need to find the correct statement out of given options. The given equation can be rewritten as :

Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
Answer:
The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth's radius plus the height above the earth - in this case, 6.59 x 106 m.
If it’s loud enough for your family to hear it, it’s best you turn it down. It could cause permanent damage to your ear drums if it’s loud enough and you could start to lose your hearing. So if your family were to tell you to turn it down, you should probably just turn it down!
500 N is the answer, you just tell that the moon is attracted towards the person because of the Earth's huge mass.
