You can easily determine the Earth's average speed. You know, or should know, Earth is 93 million mile from the Sun, thus the distance travelled in a year is pi times 2 times 93 million miles (or 149.5 million kilometers if you prefer). Divide that by the number of seconds in a year for the speed/second.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
