I was just wondering about it, how is it that wind begins somewhere in the oceans, i mean what gives air the movement to create wind? I know that winds go in different directions and so they constantly circulate pushing the other currents so that they keep on going, but what is it that created the motion in the first place? the Earth's position?, something to do with the north and south poles?.......

Thanks in advance!

what compound should i thermally decompose to get lithium oxide? is that lithium carbonate,lithium hydroxide or lithium peroxide which would be more efficient. will the lithium oxide obtained by the thermal decomposition be stable at room conditions?

I just can't understand the topic. No matter how hard I practice I never seem to get it right. And now I have a 20 pts homework about it. I'll give one number, and please explain to me how the process works. And the solution of answer won't hurt either :)

Solve.

(1 + 2i) x + 3 - 2i = 4 - 5 + 3ix

Hi guys and gals, I had this question on my cal test and for some freakin reason I couldn't figure it out. If someone knows what to do, it would help for next time I guess.

integral dy/(y^2 - 4)

I'm guessing you use the integrate by parts thing..but I could be wrong.

Anywho thanks very much :)

Not wanting to take an organizations test to prove abilities are real because they do not want the money, yet charge a lot in book stores for books, tarot readings etc. . .Isn't it possible that the reason no one takes them up on the tests is because the rules for the test are unrealistic, i.e. if they do not pass with a score of 100 then they are a fraud and will publicise it immediately, YET if they do pass the test with flying colors, it may or may not be publicised and they do not get all the money promised up front, maybe a small percentage. Would you take a test that no matter how well you do, you lose?

When the chemical reaction
A + B <---> C + D
is at equilibrium,
1. neither the forward nor the reverse reactions have stopped.
2. the forward reaction has stopped.
3. both the forward and reverse reactions have stopped.
4. the sum of the concentrations of A and B equals the sum of the concentrations of C and D.
5. the reverse reaction has stopped.
6. all four concentrations are equal.

So far these questions almost never get anywhere but what do you think? Is there an intelligent god who made the world and us? What happens when we die? Do we have a soul? What is the truth about spirits? I want your honest opinion please. With calm assurance I believe I know. Someday I hope I will be able to write a book outlining what I believe to be the truth for those who seek it.

Hi, I don't quite understand how to do this question-(the 2.5% is kind of confusing me)
Help please :)

...You decide that accepting women within the top 2.5% height bracket will be reasonable for your competition. The height of all women follows a normal distribution with a mean of 168 cm and a standard deviation of 9 cm.

Calculate the cut-off height (C) that ensures only women within the top 2.5% height bracket are allowed into the competition.

Okay well you know how our solar system is in space. Well what if you go south of it, or to the side of it, what would be there? never ending space? new worlds? cultures? i have no idea what it could possibly be. Just think, there could be millions of worlds and creatures out there. What do u think?

these things are not flat like centipedes or round like millipedes. the only thing they have in common with either species is that they have many legs and move remarkably fast.

Calculate the PRP,PRF,PD,DF, wavelength,SPL of reflector interface and period if a 3 cycles pulse emitted from a 5 MHz transducer if the echo time received was 10ms in soft tissue?

I tried to answer this homework but, I couldn't get the right answer.

PRP = Pulse Repetition Period
PRF = Pulse Repetition Frequency
PD = Pulse Duration
DF = Duty Factor
SPL = Spatial Pulse Length
