In the early stages of our solar system there was loads of "stuff" more or less all over the place. Or earth grew because its gravity sucked in all the other stuff in the earths orbit.

So why has the Kuiper belt stayed as a load of asteroids? Why don't they attract each other and then start combining, getting heavier and attracting more and on and on until you get one nice big lump of rock?

Suppose that you take a sequence of 100 numbers and transform them using the discrete fourier transform. You will get 51 complex values which can then be used to compute/plot the power spectrum. If a clear peak is visible in value (say) 20 (=0.2*N), does this mean that there is a periodic element repeated every 20 (in the original sequence) or a periodic element repeated ever 1/0.2=5 (again in the original sequence)??

I can see a visible peak at (say) 0.2*N in the power spectrum, but I am not sure what this tells me about the ORIGINAL sequence. Please explain...

Note: Please do not reply unless you really know this kind of stuff. I have already tried wikipedia and a few other sites and I need a clear and correct explanation.

Thank you!

C6H14 ---> C2H4 + other products

If the yield of ethylene (C2H4) production is 42.5 percent, what mass of hexane (C6H14) must be reacted to produce 481g of ethylene?

Can someone please help me. I dont understand. I'm more interested in the explanation than in the answer.

Assuming the compartment the hamster was in has padding and is noise resistant and the rocket has a good parachute, could the hamster live, would the G force be to much. Has anyone ever tried this before?
