Science & Mathematics - 6 November 2007

Using your own rules of evidence, I want you to prove we went to the moon. Ok to start off, your not allowed to use any video or picture evidence. You have already said its unreliable and can be messed with. Your not allowed to use any eyewitness evidence, you have already said eyewitness testimony is unreliable. Your not allowed to use any audible evidnce, you have already said the transmissions can be picked up from anywhere, heck, you could be recording a t.v. show. and your not allowed to use anything computer oriented, a computer only does what its programmed to do. I could say the rocks that they supposedly brough back could have come from anywhere on earth, perhaps miles underground from a mine. So based on this, give me an arguement to convince me we ever went to the moon! If we did, why didnt the USSR go? Why hasnt anybody went back? Remember, just like ghosts, your not allowed to use any of the above evidence as stated by your own arguements against ghosts.

A hoop, a uniform solid cylinder, a spherical shell, and a uniform solid sphere are released from rest at the top of an incline. What is the order in which they arrive at the bottom of the incline? Does it matter whether or not the masses and radii of the objects are all the same?
Explain.

For science I was supposed to watch the moon each night for the last 14 days (we stopped on Sunday), but I COMPLETELY forgot.
Is there a site that would tell me the phase of the moon, the time, and the weather conditions?

I am building an air cannon for my science fair project. The question is "What is the best possible angle for the most distance when firing a projectile?". I thought it might be 45 degrees (because 45 degrees is the perfect balance between straight up and straight forward) but I have been told it isn't 45 degrees. I thought about it and i have come to the conclusion that it must be a lower angle because of gravity and air resistance. I would also like any websites addressing this topic.

A co-worker and I were discussing snow flurries this morning. He said it was too warm outside for snow (almost 40*) (even though there were some flurries this morning here in WV) and I disagreed saying that it is possible (and I have witnessed it) for it to snow when it is 40* outside. Can anyone else give some input on this? Also, is there such a thing as it being too cold to snow? I have also heard this statement from people and believe it to be true.
