These are not hard. No not hard at all. But I would appreciate it if anyone could explain the solution to these questions to me in a manner I can understand. It is all for my studies to became a profound meteorologist and of course as you all know...to take over the world.

So anyway without further adooooooo.. here are the questions.

1.1 Neglecting latitudinal variation in the radius of the earth, what is the calculated angle between the gravitational force and gravity vectors at the surface of the earth as a function of latitude? What is the maximum value of this angle?

1.2 What is the calculated altitude at which an artifical satellite orbiting in the equatorial plane can be a synchronous satellite (i.e., can remain above the same spot on the surface of the earth)?

__Note__: no, I did not think these questions up, I, of course, got them out of a book. But if anyone knows where i can get my hands on the solutions to questions in the book, I would greatly appreciate it.
