I haven't worked on Part-A, and I don't happen to know the magnitude of the gravitational force that the Sun exerts on the Earth.
But whatever it is, it's exactly, precisely, identical, the same, and equal to the magnitude of the gravitational force that the Earth exerts on the Sun.
I think that's the THIRD choice here, but I'm not sure of that either.
<h2>Basic Research - Option B</h2>
Experimenting to determine the fundamental properties of x-rays would be an example of basic research. The experimental primary analysis tries to determine the laws of the events. The primary analysis is expected to know the stuff, its sort, its characteristics and its performance. It examines to get the speculation. To obtain wherewith the stuff performance yet not how to practice these forms for a firm determination.
The research of the characteristics of the particle to explain whatever it is, how it combines with other atoms, how it determines the characteristics of the material are some instances of primary analysis. For example examining to ascertain the basic features of x-rays. Spencer's research on WWII radar technology that drove to the discovery of the microwave furnace.
Edison's research and application of other scientists task is to create the light bulb, and Morrison and Franscioni's research was made to build the Frisbee models of applied research science.
A star's apparent brightness is the brightness seen by humans on Earth. A star's absolute brightness is its actual brightness and does not depend on where the star is viewed from.
Answer:
No fallacy
Explanation:
The statement that at least 50% of the students at Northern State own an iPod is best categorized as no fallacy.
This statement is very true and consistent with the facts presented in the passage.
A fallacy is a mistaken belief usually based on biased arguments.
Total number of students sampled = 200
Number of iPod owners = 150
Percentage of iPod owners = 
x 100
Percentage of iPod owners = 
x 100 = 75%
We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.
