My nose hasnt bled since I was about 24, Im 33 now, but Ive always been curious about this. And when I say bleed, I mean BLEED. It would 'pour blood' like someone turned on a faucet. NOT SQUIRTING, but coming out fast and for a long time. My granddad freaked out once and rushed me to the hospital when I was very very young. Once a doctor set a long wooden Q-tip on fire and SHOVED it up my nose when I was around 7, THAT SUCKED. It did nothing to keep it from bleeding in the future. At times I would wake up and my pillow would be SOAKED in blood and my mom would be cleaning me.Or I would just be sitting there doing school work, and suddenly my paper would be all bloody with NO warning. Ive always been a pale child. I come from an irish american indian heritage. I also find that I cant fight anyone without blacking out within a minute, without the nose problem just everything goes black and without being struck, just the struggle itself. Doctors dont know why my nose bled. I DONT PICK IT.

here's the prompt:
You are an archeologist in the year 4005 and you find an ancient tool chest from the year 2000. Describe one of the tools in the chest, describing the simple machines involved in its shape and use.
so what i am looking for from you, is what tool would you choose?
i would like an easy tool to write about but also a good tool that has many spimple machines involved with it.

1. When sulfur burns, it reacts w/ Oxygen in the air to form an oxide of sulfur (SO2). Compare the Physical properties of SO2 with the oxide of MgO (produced when Mg is burned).

2. If Na is reacted with Fluorine, would you expect it to be ionic or covalent and why?

3. When P is reacted with O, is it ionic or covalent?

4. Is it true that covalents are only produced from 2 gases?

5. Explain why oxygen and sulfur are in the same group and why are Phosphorous and sulfur next to eachother going across the period???

Does anyone know how to do this problem and can explain to me? thanks.

(Note: j = imaginary number)
the active power of an ac circuit whose current I=a+bj and voltage V=c+dj is given by P= ac+ bd. Find P when I=5(cos 45 degrees + j sin 45 degrees) and V=110 (cos 30 + j sin30) by first changing the numbers to rectangular form.

B. find the impedance Z in polar form of the circuit. Note: Z=V / I

In 1998, Bob Ballard - the discoverer of the Titanic's remains announced that the Black Sea had once been a 'freshwater' lake and that roughly 7000 BC, the earth holding back the Mediterranean Sea (thru the Bosphorus Sraits) collapsed, resulting in massive flooding that the ancients embellished into 'Flood' myths. This week, scientests announced that roughly 4800 years ago, a large meteor (s) crashed into the Indian Ocean that resulted in a 600 foot tidal wave that hit Madagascar and by extrapolation, all around the Indian Ocean. Wouldn't you agree that modren Science can now explain the reason why so many peoples from those area's had 'flood' myths?

Here it is: My friend, Dylan asked our science teacher today, "If a Turtle fell on it's back, would it be able to turn back over on it's own? How long would it take?"
Thean our teacher said, "I've wondered that, too."

That's my question: Would they be able to turn back over on it's own and how long would it take?
