PRE-LAB Instructions: Print out these pages. Feel free to refer to the lab instructions and other materials, your physics textbook, other students, etc. to help you to ponder, understand, and work out answers to the following question(s). If your instructor requires you to turn in this prelab, please show your work& answers in the space(s) provided.
PRE-LAB Questions:
1) You want to find the volume of a metal sphere (Note: the formula for the volume of a sphere is V = 4/3 pi r^2 , where r is the radius of the sphere). You nmeasure the radius of the sphere to be r = 2.18 cm, with a measurement uncertainty of± 0.02 cm, what is the volume of the sphere as well as the corresponding uncertainty of the calculated volume?
2) You measure the mass of the same sphere used in question 1, and find that its mass is m = 122.2 g, with a measurement uncertainty of± 0.1 g. What is the density of the sphere as well as the corresponding uncertainty of the calculated density?
