Science & Mathematics - 14 January 2007

I am doing a science project and I need help of where I could get acid and base. Not just any kind of acid or base. I need hydrochloric acid and base (NAOH). I am trying to make a pH of 1,4,10,and 14. That is why I need specific types of acid and base.

A polynomial equation of nth degree has n roots. Does that mean this equation has 2/3rds roots? What are the roots, which may include complex roots?

Yesterday I went outside to see the comet during sunset, and could see it after the sun went down through binoculars. In a few days the comet is going to swing around the sun and then be only visible to people in the southern hemisphere during sunset. My question is simple really, couldn't I just still see the comet in the northern hemisphere right before the sun rises?

Nobody cares about global warming. The tip of Florida is going to be underwater, and so is Canada, Alaska, and all of the border states! If you could just walk to the store that is five minutes away and Recycle, also if you Turn off your light when you are not using it, You can stop this.

It may sound like an absurd question, but I really would like to know the kind of response that people would have. So imagine that you learned this about you neighbor. You would likely be shocked. It has many implications. What would you do?

A uniform beam has a mass of 236 kg and has 5 forces working on it. F1 and F2 are pushing upward at each end of the beam while F3 (3900 N), F4 (2990 N), and F5 (1960 N) are pushing downward in between the two upward forces.

There are four distances. D1 (1.84 m) is between F1 and F3. D2 (4.16 m) is between F3 and F4. D3 (2.90 m) is between F4 and F5. D4 (1.02 m) is between F5 and F2.

Calculate F1 and F2 for the beam.

Can anyone explain how to do this problem?? I have drawn a free-body diagram, but I am at a complete loss as to what to do now.

if a particle travel through time then its existence in this time will be over and total mass or equivalent energy of the universe at this time will decrease,and at same time energy of the universe to which it has been transported increase(by an amount equal to its own energy) defying conservation law.

a.) decrease by a factor of 4
b.) remain the same
c.) increase by a factor of 2
d.) decrease by a factor of 2
e.) increase by a factor of 4

The answer is d.) decrease by a factor of 2, but I got a.) decrease by a factor of 4. What did I do wrong?

The equation you would use is F = (GM1M2) / r^2... right? (where G equals gravitational constant, and you know what the rest of the variables represent)

Help, please. ASAP.
