This is a test of honesty, you can view the book. Don’t view the answers of friends, Don’t ask the answer to another physics teacher. Do it by yourself! because honesty is very important. These test were collected on Tuesday on 13 November 2012. Do the test on your sheet (paper)! Print the question and combine or glue your answer with the question.
