Imagine you roll two idintical 12-sided dice (regular dodecahedrons). You roll them at the same time, and make a fraction out of the two numbers that come up. To make the fraction, use the smaller number as the numerator and the larger number as the denominator. Obviously, if the dice show the same number, it doesn't matter which is the numerator (the fraction will be equal to 1). What is the probablility that the resulting fraction is less than 1/2?

This is just something to think about for a while. One day after 9-11-01 I started paying more attention to things. One of the things I found interesting was the clock. I took the Star of David and applied it to the clock and began to write down the numbers in the order of the points starting at 12 clockwise to 10. !12-2-4-6-8-10. Moving in the clockwise motion I turned the Star to 1-11. 1-3-5-7-9-11. Writting those numbers below the first row of numbers. So I'm making my way down through the numbers and a distinct sequence began to form. 9-11-1 was moving from left to right all the way down this Tower of numbers until I got back to 12. I estimate that something big is going to happen in 2012. I got the confirmation of something big while watching the Bible code on the Discovery channel. Also read Genisis 11:1-9. That's 9111 backwards. It talks about the Tower of Babel and the great city in the east. Try doing the clock thing yourself and read Genisis. Tell me what you think.

A rotating rod that is 15.3 cm long is spun with its axis through one end of the rod so that the other end of the rod has a speed of 2000 m/s (4,500 mph).

a. What is the centripetal acceleration of the other end of the rod?

b. If you were to attach a 1.0-g object to the end of the rod, what force would be needed to hold it on the rod?

Please help me with this problem.
