A. None of the above B. 2.1+-0.5831C. 2+-1D. 2.1+-0.8 E. 2.1+-0.2 F. 2.1+-0.6

The following quantities were measured as follows: a = 15.2 + 0.5m b = 13.1 + 0.3 m c = a - b Calculate c and its uncertainty oc and. You will need to not only do the math correctly, but also decide what figures in c and oc need to be reported. Hint: First calculate c and oc . Then decide how the result should be stated correctly
