I noticed on one of the TAPS Ghosthunter episodes that they were in Ireland, and were also searching for fairies as well as ghosts, being the cause of phenonmena, etc. It seems like they were big believers in fairies in that region. I do not hear much talk of fairies around except for maybe the tooth fairy.

Is belief in fairies kind of like the belief in leprechauns? Are they found only in certain parts of the world, whereas ghosts are supposedly found everywhere or at least where people believe in them?

First, I found one piece of the big rock and I found the other piece a few centimeters apart. Given the fact that this stone is very hard, I think it was not broken by humans, but by another geological event (earthquake, landslide, avalanche, etc) There are no other rocks like it in the vicinity. Some people tell me they have seen others two kilometers from this one. When hit with a metallic tool, it emits light sparkles. What does this tell me about the history of this area in Haiti characterized by red soil, mountain. There is a mountain 7 to 10 miles away which looks like an extinct volcano one one side. The ocean is about 12 miles away on the other side.

Maybe they have really big space stations...and have space ships on them. Since that makes them closer to the earth...they are able to visit our planet?.(The same as our astronauts .go to space stations and then come back here.)
(This is what happens when you run out of questions to ask! Your mind becomes very "creative". (The scientists on here will recognize that I know NOTHING about the space stations..or the Universe.)(Just pretend I'm a 3rd grader asking this.! Be nice!!)(Don't bruise my creativity!)

Inebriated humans is not an answer! :-P

I was wondering, which animals won't be able to stand up on their own after falling over?

I have heard it with cows - from "cow tipping" myths - however, I don't know how true that is. I know cow tipping itself is not possible, but is it true that if they did fall to their side, they wouldn't be able to get back up on their own?

Are there any other animals that can't get back up on their own after falling? Or is there any history of such animals which Darwin has naturally sent to the recycling bin?

I need to perform my science fair experiment over winter break. So I cleared it with my teacher and brought home the equippment. I made 60 Petri dishes of agar and they are in my refridgerator. They're not setting up though. This might be because I cooked the agar in the microwave with the water, instead of boiling the water and then dissolving the agar in it. It's been 24 hours now, and they're not really setting up. Any advice?

I am looking to define "center of gravity" in relation to torque...i.e. torque arms, etc. Imagine a ruler on a pivot point, then how would I define its' center of gravity??

I saw it on CSI Miami a few weeks ago, and I'm really curious about that. I konw that they kind of explained how it worked, so I know theoretically it could work but what about in the real world?

Some of my closest relatives are orang-utans and they share about 97 percent of the human genetic makeup. Great conversationalists and one of them - Harvey - consistently beats me in Chess.

When the temperature drops, outside noises such as trains, trucks, horns, music from cars, etc seem like they are right outside the door instead of a mile away.

Please answer it using only SI units, none of that primitive crap they use in the USA. Please show all work along with any formulae used, preferrably in steps, so that I can learn how to do this on my own as I'm rather stuck at the moment with this question. The question is as follows:

A sled of mass 50kg is pulled along snow-covered, flat ground. The static friction coefficient is 0.30, and the sliding friction coefficient is 0.10.

d)Once moving, what total force must be applied to the sled to accelerate it 3.0m/s^2?

The help would be most appreciated! I need this damn physics course to begin my career as an electrician.
