Students watching a large mass swing on a long cable decide to determine the length of the cable assuming it acts as a simple pendulum. They make several measurements of the time the mass goes through ten complete cycles. They measure the time for these ten cycles to be 88 1 s. Because this is an experiment they realize they must take g = 9.8 m/s2 in this case. Given the uncertainty of the data which of the following would be the best indication of the length of the cable? (A) 18 to 19 m (B) 19.1 to 19.3 m (C) 19 to 20 m (D) 20 to 21m
