Is it possible to connect multiple power supplys, say from two or three or 6 smaller generators, to have more power? Like 1,000 little fans on your roof... And if so, do you have a link where there is information about it?

from f.p.'s cos(x + delt x/2).sin(delt x/2) all divided by delta x/2, making a complex fraction;
as delta x approaches zero, the numerator of sin() approaches zero, but so does the denominator, (delta x/2).
Why can that apparent problem be so easily ignored?

How do scientists know what is inside the earths core. They say, its a hot bowl of lava, but how do they know when they have never been able to go there, because even metal ships or drills melt at that high temperature.

A small wooden boat floats in a swimming pool, and you’re observing the water level at the edge of the pool. Consider the following situations, and explain whether the water level will rise, fall, or stay the same:
(a) The boat is removed from the water
(b) The boat was originally holding an iron anchor which is then removed from the boat and placed on the shore.
(c) The boat was originally holding an iron anchor which is then removed from the boat and dropped in the pool.

I can remember watching two cartoons that did that geographical faux pas: 1) "Count Duckula" where they transported the castle 2 Down Under instead of Freud's country hoping 2 seek professional help, & 2) "The Simpsons," where the German typeface of Australia's Parliament had 2 scribble in the "al".

Can there b other situations 4 that error 2 happen? I'll award a thumbs-up & maybe Best Answer if you've done so & can tell a good story about it. & what about Swaziland & Switzerland? Slovenia & Slovakia? (Bush 43 did that while running 4 office.) Or maybe 2 cities w/ the same name, like St. Petersburg or Paris, Odessa & Bakersfield (all 3 in TX).

By this, I mean portable laboratory grade lasers that could cut through at least plastic (heck, even Wicked Lasers can do that). I mean powerful lasers that can at least cause severe (3nd degree & up) burns in about half a second. It must have a sustainable power source (continuous for at least 5 hours). It could be a continuous beam or a rather silly "blaster beam." Is it possible today?

My multi-vitamin has about 100 or more percent of the recommended daily dose for each mineral and vitamin. If I get extra vitamins and minerals from my meals and from this vegetarian protein shake I take, will I be getting too much vitamins/minerals? Could I overdose?

For instance, my multi has 35 mg, 175% of Niacin; my shake has 20 mg, 100%. In addition to that, I will probably be getting some extra niacin from the foods I eat. Am I getting too much?

Would it be safe to take my multi along with my two veggie shakes daily?

If you do not understand my question, please ask in your answer, as I will check back to answer anybody's questions.

Please tell me the source of your information- whether it is from google or you are a healthcare professional.

I have a bunch of ideas of what I want to be when I graduate HS. I have potential. I know that. One of them is being a weapons engineer for either the US Military (preferably USMC) or for an armory company (Like Colt or Springfield). But right now, I'm just curious about the flight pattern of... say... a catapult? But I don't want to wait till Junior year to learn physics, and don't want to spend money on a book. Any good sites?

I want to reduce the 12 volts from my battery into 7.2 volts. (I'm a noob at resistors) How would I go about doing this? Can some one give me a list of resistors I would use to do this, and possibly even a diagram of the circuit? The easier and the cheaper it is, the better.
