Answer:
What do you need help with?
First of all, leaving family and friends and going to the war needs a lot of courage to do...and after going there if you are going to fight against your own country, first of all you feel guilty for doing such a thing, second of all you will never make it against your own country, because even if you win the war you will feel guilty for rest of your life which is like you lost.... It is a very hard time difficulty for sure if things are going to happen like this
I would probably not fight against but for my country

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.

The answer is D, because the argument is sectioned neatly and easy to understand.
