1. What are the different types of errors encountered in an experiment? Give two examples of each. 2. How many significant figures are there in the numbers 6.429 x 103 and 3.18785 x 10? How many significant figures are there in the answer when these two numbers are multiplied together? Divided by one another? Added together? 3. Express the following numbers in scientific notation: 673402.2, 34.623, 0.00008730, and 1,232,000. 4. The accepted value for the acceleration of gravity at the surface of the earth is 9.8 m/s. In an experiment, I measure the acceleration of gravity, and get the result 9.6 0.3 m/s. Determine the experimental discrepancy between my value and the accepted value, both a fraction and as a percentage. Is the experimental discrepancy consistent with the relative error of my measurement? Why or why not? 1. What are the different types of errors encountered in an experiment?
