***i've always thought how funny it would be to yawn in a meeting or something at work, then watch the yawn travel around the room and make everyone look like they're tired - like a mexican yawn***

If anyone does this in work tomorrow for the shear hell of it let me know how it goes - i'm just curious that's all.

****hard to categorize this question? !!! ****

We spent a lot of time at school studying properties of triangles and quadrilaterals. There are many quadrilaterals Yet there are only regular and irregular or concave/convex pentagons, hexagons etc. Why are triangles and quadrilaterals so important?

I'm confused on how to do a problem like this. I'm supposed to find out how to find out what P is.

An easier problem I understanded is:
A=1/2*j*m
2A/j =m

Can anybody help me with the first problem?

ithink the answer would be because it is less dense than water so the bottom layer but here goes the question..
if a sample of recently prepared 1-bromobutane is washed successively with water, cold concentrated sulfuric acid, and then very dilute 5% aqueous sodium bicarbonate solution, tell which layer is the 1-bromobutane in each of the three washings.

Can anyone help me on creating an automatic Fan (no electricity, which blade knots enough to produces some air) a good engineer can answer that without any difficulty, I hope you can answer that in time, it’ll be very useful to me, I tried to search but couldn’t find anything, just like an automatic wrist watch, no batteries but still moves.

Since square root functions have both a positive and negative answer, can negative mass exist? I refer to the relativistic mass/velocity equation that I cannot duplicate with this format. Physicists will know it. If negative mass DOES exist, does that imply negative momentum, force and energy in the Newtonian world

The specific heat of most oils is about 2J/g degrees celcius, compared to a value of 4.184J/g degrees celcuis for water. Why do you now think oil, rather than water, was the liquid of choice used by castle defenders against invading forces?

Sorry if this is a completly stupid question but i had a dream a while ago that i made this thing called a bio dome, and since then i have been thinking of this idea! i know it may sound stupid but i have patent it before asking... the idea is a dome like a fish tank that could simulate the world's weather, in the dome you have maybe a replica of your house and garden ect maybe a pond and bonzi trees to simulate real trees you get the idea then have it simulate weather! so you have water in there and have a light that goes around the bowl simulating the sun 12 hours light 12 hours dark could you make it simulate weather i.e. storms ect if you need more info then ask! cheers
