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.

Even though you didn't give us any excerpts, I can still try to help you.
I would say the correct answer is that <span>Grendel is described as an unfeeling creature in Beowulf, but he is a sensitive and emotional character in Grendel.
Based on the system of elimination, that should be the correct answer. B is incorrect because he is scary and monstrous, not comical and ridiculous; C is incorrect because Beowulf acts bravely and honorably in Beowulf, not the other way round; D is incorrect because there is no sympathy towards Grendel in Beowulf because he is a ruthless monster. So this leaves us with A as the correct answer.
