Choose ONE of the following scenarios we discussed in lecture (Ocean Acidification, Evaporative Cooling, or Floating Ice and Increasing Temps, from left to right) and briefly 1) explain the science behind what is happening and 2) why your scenario is important on a global scale. Please provide enough details (e.g., the properties of water) to support your answer.                       

The surface tension of water is a phenomenon that uses between water molecules (but not the air molecules above) to allow certain organisms to walk across water. 

*What size is the following matrix? Also, is it a square matrix, a column matrix, a row matrix, or none of those? 457{“version”:”1.1″,”math”:”457″} Your answer:  This matrix is a ____ x ____ matrix. It is a _________ matrix. The first two blanks should be filled in with numbers.

A witch’s house contains bats and spiders. In total, there are 23 creatures in her house (not counting herself). Altogether, these creatures have 112 legs. Every bat has two legs and every spider has eight legs.  How many bats and how many spiders are in the witch’s house? Fill in the blanks to give me your answer: The farmhouse contains _____ bats and ____ spiders. You must set up a linear system. You may then solve that linear system by any method. I want to see your work for this problem. If you solve the problem using matrices and your calculator, the work I want to see will include the following: the matrix that you put into the calculator, the matrix that you get from the calculator, and also your answer. (That’s three things you must show.) You will need to submit your work for this problem to the Dropbox folder “Work for Test #2”. Failure to follow these instructions will mean that you will get 0 points for this problem, even if you have the right answer.  For example, simply guessing what the answer should be is worth 0 points.
