If all matter has some gravitational pull, and the only explanation to magnetism is electrical energy, that'd mean that all matter has it's own electrical fields. Even nonconducive objects that wouldn't conduct electricity. Are all things magnetic? Explain gravity's relation to attraction of objects.

I quite enjoy the Waltzer at the fair, but it never seems to spin as fast as the other cars with more people in. Sometimes, it hardly spins at all. I'd be interested in learning the science behind it, so my friends and I can put it to (maybe-not-so) practical use. I'm guessing it probably hads something to do with weight disrubution, but after that I don't really know. Anybody like to educate me in the ways of the Waltzer?

Will it be Global warming, Asteroid, Volcanic activity (super Volcano), Extra-Terrestrials or something else?

My money is on the ruination of our planet over time and the use of all its resources. We will end up with a barren lifeless planet.

I have adjusted the temperature of my water heater to a very high degree, primarily because I don't use the dishwasher, and the hot water helps to sanitize the dishes. I live alone so I don't have to worry about others being scalded.

I have 2 questions:

1. Does hot water have a self-insulating effect? If I keep my water at a higher temperature, does it use less electricity because the hot water is keeping itself hot inside the water heater? I am hoping so, because I like to conserve electrictiy, however the sanitizing aspect is extremely important to me for health reasons.

2. At a certain temperature, does the hot water start to damage the copper plumbing? If so, what temperature?

Apparently it is some lost ancient planet that is in a different orbit around the sun so we can't see it and it doesn't revolve around the sun like the other planets do... It apparently also collided with out planet to create the moon and was discovered by the oldest civilisation 6000 years ago... What are your thoughts?

Obviously not in a verbal way but do they have some way of interacting with each other?

What have recent fossil discoveries and studies of DNA added to the theory of evolution? Are there any other recent developments?

Here is where Yahoo Answers excels. Yes, I could look it up, but people wanting to advocate their point of view are often more motivated to "make the best case."

My views are not at issue. What info do YOU have? I have only heard dribs and drabs. Links would be great. Thanks.

They're still in the early phases of space technology, but have high hopes of putting a man in orbit by 2017. Rather than using rockets to propel their Aztecnauts into space, they're going with a much more natural route. After the Aztecnaut injests large amounts of refried beans, chili and beer, they don their specially crafted suit. Within 30 minutes, they're at the launch site. By this time, they can no longer hold in the vast amounts of gas that their food is producing and commence with very powerful farts, which are inturn lit by technicians wielding matches.

So far, Mexico has successfully launched an Aztecnaut roughly 30 meters into the air.
