<u>Answer</u>:
B: When running for a political office, a candidate must be willing to fight for his positions, to state his beliefs articulately, and look confident while doing so.
This statement has been written correctly.
<u>Explanation</u>:
Punctuation is very important in a writing. The reader can understand the meaning properly and even the writing appears more appealing. Without punctuation, correct meaning might not reach to the reader. He might lose his interest in reading.
Option B has correct punctuation marks, i.e. there is a comma after office and after positions. Also, “to state his beliefs” is grammatically correct. In other options, use of “stating his beliefs” in Option D and “to look confident” in Option C makes both the sentences grammatically wrong. In Option A, use of ‘state his beliefs’ and ‘to look’ are incorrect as well.

From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.
