Hi. I recently asked a question regarding the point of these riddiculous creatures, although now I would like to know that since they only seem to emerge in September, what do they do for the rest of the year? Where do they hide? How do they survive the winter and snow etc.? Please enlighten me!

(PS. Stupid answers are welcome...)

You are part of a search-and-rescue mission that has been called out to look for a lost explorer. You've found the missing explorer, but you're separated from him by a 200 m high cliff and a 30 m wide raging river. To save his life, you need to get a 4.4 kg package of emergency supplies across the river. Unfortunately, you can't throw the package hard enough to make it across. Fortunately, you happen to have a 1.8 kg rocket intended for launching flares. Improvising quickly, you attach a sharpened stick to the front of the rocket, so that is will impale itself into the package of supplies, then fire the rocket at ground level toward the supplies. What minimum speed must the rocket have just before impact in order to save the explorer's life?


I know the rocket needs to travel 202.237 m (the hypotenuse of the triangle). So d=202.237. I am lost however, where to go from there.

Any ideas?


Thanks

This is one of the of the questions among many for my scientist friends. Please bare with me:
The big bang according to my understanding say that matter from ther universe were drawn together by gravity and then exploding into the universe we now know over a period of millions and millions of years....right??

I just wonder: Where did the matter from BEFORE THE BIG BANG come from. (some say "from a previous big bang") It just doesn't seem to answer the question because then where did those matter come from and so on.....
One of the rules of arguments in theology is that you CANNOT get something from NOTHING. How does matter in the universe (before the big bang) just magically appear??? I think we have another missing link..

And besides this theory doesn't explain the vastness of the universe and why it sooo big. How did all of that space for the big bang to take place emerge.

Conclusion: There MUST BE AN ALMIGHTY GOD.
