What would human evolution create in the future?

I heard of a possibilty from my Gr. 8 Science teacher: our eyes will grow larger, our noses will sink into our face as well as our ears, our teeth won't be as sharp, our pinkies and little toes will cease to exist and our lips not as distinguished. We may also have larger brains. I think it was a joke, since his description was close to that of the 'Little Green Men'. What do you guys think?

A satellite is in a circular orbit about the earth (ME = 5.98 1024 kg). The period of the satellite is 1.10 104 s. What is the speed at which the satellite travels?

I am studying for a physics final and this is one homework question that I got wrong. I can't seem to find the right combination of equations for this problem. The correct answer is 6110 m/s. Any help would be greatly appreciated.

Will You Die If You Get Shot in the Head?

Ok my friend in my class is getting on my nerves. And I want some body to answer this question. I know the questions a lil stupid but please just answer. Yes I know you CAN die. But you can survive. My friend said that as soon as you get shot you'll die. I, to be honest do not believe that. Whether the shot coming from a far distance or long. I understand you can die first thing, but you have to be more realistic. geez they play to much violence. So some1 just back me up here. And if i'm wrong I'm wrong. come on ANSWERS!
