Science & Mathematics - 19 September 2007

The contemporary scientific community and even Einstein has predicted that on Dec 24 2012 there will be a polar shift here on earth because of Planet X or Nibiru disrupting our solar system. Basically they are saying that the north pole and south pole will switch in a matter of seconds , causing Earth to spin the other way around and therefore cause chaos here on Earth , they estimate that every calamity from A-Z will happen , and that a 3rd of the world will be wiped out. Is this myth ? Or is this really real ? How come NASA or any other space agency isn't alerting us about this , shouldnt we start preparing for this ?

Theory 1: Conditions on earth allowed the spontaneous formation of organic molecules which then formed basic cells.

Theory 2: Microbes arrived on an asteroid that impacted on the surface.

What evidence is there for each/either???
How can you explain each/either???

This is my biology homework and I don't have a clue, so anything explained nice and gently would really help!
Thank you very much.

When Alicia and Zoe ride a carousel, Alcia always selects a horse on the outside row, whereas Zoe prefers the row closest to the center. These rows are 19 ft 3 in and 13 ft 11 in from the center, respectively. The angular speed of the carousel is 2.4 revolutions per minute. What is the difference, in miles per hour, in the linear speeds of alicia and Zoe?

Thank you. Didn't have many characters to work with so sorry if it's a bit unclear. Basically By using SI unit analysis I need to know if that equation is dimentionally correct.
