You and a friend perform an experiment to determine the gravitation acceleration near the surface of Earth in Hays (perhaps by performing the experiment described in the example lab report). Based on your data, you calculate the acceleration to be (9.96 0.02) m s 2 , your friend gets (9.51 0.07) m s 2 . The accepted value is 9.81 m s 2 . (a) Whose results (you or your friend) has the lower relative uncertainty? (b) Whose results (you or your friend) has the lower percent error? (c) Whose results (you or your friend) has the lower percent difference? (d) Do either of the two results agree with the accepted value? (e) Does your result agree with your friends
