Everybody has to share this planet, yet these idiots want to fight about oil and differences and whatnot. It would only be a matter of time before the planet becomes a little too unstable for people to live on it, so we should research more into space and look for habitable planets/moons. Everybody should join forces so we can progress in finding cures for diseases and expand into space as well. Does anybody agree with me?

thermal conductivity is defined as:
k = [(Q/t)x] / AT where:
(Q/t) = rate of heat flow
x = thickness of material
A = cross sectional area of medium
T = temperature difference

Show that this is analogous to the definition of elecrical restivity p = (RA)/L = V/I A/L

Does the length of a segment refers to the distance between its two endpoints?

A manufacturer purchases a part for use at both of its plants-one at Roseville, CA, the other at Akron, OH. The part is available in limited quantities from two suppliers. Each supplier has 75 units available. The Roseville plant needs 35 units, and the Akron plant requires 75 units. The first supplier charges $70 per unit delivered to Roseville and $90 per unit delivered to Akron. Corresponding costs from the second supplier are $80 and $120. The manufacturer wants to order a total of 75 units from the first, less expensive, supplier, with the remaining 35 units to come from the second supplier. If the company spends $9750 to purchase the required number of units for the two plants, find the number of units that should be purchased from each supplier for each plant.

P.S. please show the matrixes needed to setup and solve this problem.

... G Forces upon players during a punt return?

http://sports.yahoo.com/ncaaf/news?slug=ap-ncaa-rules&prov=ap&type=lgns

He states in this article that it will increase G-Forces upon the players. But I'm thinking after accelerating over about 10-15 yards each player is going about as fast as he can.

So I'm not seeing a big difference in moving the kickoff 5 yards.

Does the perdue coach have some advanced knowledge of newtonian physics I am missing here?

How does it explain (and I mean explain, not disprove the alternative) the fact that meat eating creatures survived the first hundreds of years after the flood without eating? (because if they ate, they wouldnt let the "kinds" reproduce and repopulate the earth?. and how do you explain that, according to you, the reason "aledgedly more evolved" or more complex species fossils are found nearer the surface of the ground because they were fleeing from the flood and since they are more intelligent they made it to the high ground, but some slow dull animals like moles and insects apparently outsmarted and outrun raptors and flying species?
