t (s): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
x (s): 0, 5, 20, 45, 80, 90, 100, 100, 100, 100, 80, 60

1. find the greatest speed. I don't know which one it is since there are 4 points of "100"
2. least speed? Do I count "0" or"1"?
3. the speed is constant? would I choose 6, 7, 8,9?
4. average speed of particles for the first 7 s?
5. find the instantaneous speed of the particles at 3s.

Could someone explain all of this to me?

For some it will be classical music. For others it will be rock. A lot of people say music makes them tingle inside. What is the mechanism behind this?
I reckon it causes the release of happy hormones too. But that would be for another question ....

If I make a costume that emmits invisible light, like gamma rays, ulraviolet light and other lights that cannot be seen by the human eye. Do you think it would work? If I somehow manage to make a costume made of spandex and apply hundreds of light emmiters all around it that emmit that type of light. unseen to the eye. I think it would work, I wouldn't become invisible, but you wouldn't be able to see me because all you would see if a shadow or maybe nothing. I don't know yet, I could totally become invisible to the human eye. Just think even a suit made of all natural white light almost would make me invisible. what do you all think?

Ant body parts are designed for their size. They look spindly because of the ratio of body mass to cross sectional area is low. Coz we are bigger, we need more cross sectional area to support our mass.

So, if an ant can carry say 5 times its body weight, then if we were shrunk down to ant size (but our body proportions remained the same), how many times our own body weight could we lift?

Since scientists said animals do not have a sense of themselves, therefore they will not know they are pandas or dogs or cats, for example. But we often see animals fighting or playing with their own species, then they must know what they look like. Anyone can explain why?

Yeah.. thats right. Steel.
Maybe stainless steel.
If it was an exceptionally hardcore woodchuck (steelchuck?) and could chuck steel... how much wood would that enable it to then chuck by comparison, if it could even be bothered to chuck wood any more once it had powered up enough to take on metals?

Would it be called a steelchuck?
If it chucked nuns, would it be called a nunchuck? ... Definitely not nunchaku... but still.

And who would win in a 3-way fight between a woodchuck, a steelchuck and a nunchuck?

[For bonus points: Am I insane or just eccentric?]

What's the process, and how much energy would it use?

I'm guessing the very low concentration of CO2 in the air will make this quite an energy intensive process. In fact it will probably take more energy than was released when the carbon was oxidised in the first place. But bear with me on that part. I'm just looking at the extraction for now.

Thanks!

there is a prophesy about the old site where babylon was, i think its fuluga in iraq, that this site would slip into the river euphrates, setting of a world wide earthquake that would bring down the cities of the earth, i wondered if this site had ever been explored for weaknesses to get an early warning.

Does anybody know how these equations are done? Here are a few more examples:

g (x) = x^2 + 7.5
g (x) + (52x)^2
g(x) = -2x^2
