Vernier Scale and Thickness
Questions: 1. When you performed Step 2 of the procedure, you actually made a cylinder of M&Ms. The cylinder was rather "smushed," and the height of the cylinder was the thickness of an M&M. Recall that the equation for the volume of a cylinder is V = (3.14)r2h. A. Rearrange the equation for "h." Show your work.H=v*(3.14)r^2 B. Using the data from Table 1 and your equation, calculate the average thickness (height) of an M&M for each trial. Record your calculated values in Table 1. Hint: Students often forget that they must use the radius, and not the diameter, in the equation. Copy Table 1 into the assignment. .6915 C. You now have two values for the thickness of an M&M in Table 1. Determine the average M&M thickness using these values and record your value in Table 3. .689 D. You have just determined a value for the thickness of an M&M using the indirect method. What makes this method "indirect"?.683 E. You have just determined the value of the thickness of an M&M using the indirect method. What the method indirect?You have to define your answers in Table 1 and find out all the other measurements. 2. When Step 4 of the procedure was performed, a vernier caliper was used to measure the thickness of an M&M. F. Using the data from Table 2, calculate the average M&M thickness and record your value in Table 3. Copy Table 2 and Table 3 into the assignment. .6915 G. You have just determined a value for the thickness of an M&M using the direct method. What makes this method "direct"? You have the answers for the table so that you understand the concepts. 3. Which method (indirect or direct) yields the "best" value for the average thickness of an M&M from the package? Explain the reasons for your choice. They both come out as .69 therefore, they are the same answer.*Registered Trademark
