seen a lot of web pages post statements that all we really know are the effects of gravity, but dont really understand what it is! Maybe thats why no one can truly tell anti-gravitational scientists that they are wasting their time!

Equipments that can be used during the lab are the following:
(Tirrell burner, rubber tubbing, evaporating dish, 4 beakers, filter paper, a funnel, watch glass, scoopula, forceps, glass stirring rod, distilled water, wash bottle, magnet, tape and zip-lock bags.)

Using the above list of equipments, the objective is to separate the mixture (containing sawdust, salt, sand, and iron) into four pure individual components.

I just need the procedure of this science experiment. Please list them out in bullet points, not in paragraph form. Thank you so much for helping!

I was wondering what the force was a person uses when that person moves themselves back and forth on a swing set. Like when they kick their feet back and forth, is that like, intertia or something? or.. what is it?

This insect was spotted in Northeastern Ontario Canada on the edges of a nearby lake. I am glad I had my camera because I have never seen another like it!

could it be used to measure other distances? how (as, with the golf one, it tells you to gauge by the bottom and top of the flagpole, objects not always conveniently about the place)? how may its accuracy be determined? be gentle with the math, por favor; algebraic notations, and above, burn me like holy wa... i mean, uh, acid. definitely acid (i know it's a trig problem, so i'm wary).

I have this notion that I should hose water on my roof when it gets really hot outside (like 100 degrees, Florida). I can almost see the heat coming out of the shingles. I know that evaporation creates cooling. So if I sprinkle water on the roof it should get cooler. Haven't tried it because I don't want to look like a dweeb to my neighbors.

2 over 1 integral (x sqrt(x-1)) dx. I got the answer 2/3 but the book said it was wrong. I did u = x-1, du = dx. then 2-1 = 1 and 1=1 = 0.. then 1 over 0 integral (sqrt (u) du) then (2/3)(u^(2/3)) and finally (2/3)(1-0) = 2/3 but book got something pretty off and I think i got the u and du wrong but i dont know what is rigth then.
