Plagued with scandle. We put men on the Moon in
'69 with sliderule technology, and now all we do is go around and around and wait for the next disaster. By now we should have been on Mars. At least we got Tang for all the billions we've spent.

Hi. I would really appreciate it if somebody could please help me with my homework or else I get a big fat zero. The teacher wouldn't explain it to me and he told me to figure it out on my own and left. What a jerk. But anyway, whoever gives thorough step-by-step instructions in the easiest way will earn Best Answer by me. Thank you ahead of time! Oh and I don't know what I am suppose to write for the square root symbol. So I will just put / meaning square root. Like /4 would be the square root of 4. There are about 40 problems in my assignment so don't think that the following problems are just so you can do my homework for me hehe. I just picked out the ones that would probably be the hardest.

Simplify each expression:
1) /50 over 9
2) -2/10 times /8
3) 2/126 over /14
4) -/189
5) 4/6 + 3/2 over /6
6) 3 + 2/7 over /7

7) Adding/Subtracting: /8 - 15/2
8) /12 + 7/27
9) -3/2 + /18

newton's third law governs the interaction between the earth and the moon. it states that for every action there is an equal yet opposite reaction. so if the earth exert a force the moon will also exert an equal force so what about meteors?

I want to view them from "Google Earth" but don't know where they are located or, for that matter, even what they are called. I hope you understand what I am trying to describe. They are these huge images that you really can't tell what they are from land just ditches, may be rocks too--heck if i know! Please, it you know answer this question so I can show my grandkids what I'm talking about.

A block whose weight is 41.6 N rests on a horizontal table. A horizontal force of 33.3 N is applied to the block. The coefficients of static and kinetic friction are 0.699 and 0.352, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s2 as the acceleration.
