VI-1Diameter of bob using ruler: d= 2.40cm, 2.50cm, 2.50cmRange of diameters (ruler) = 2.50cm - 2.40cm = .10cmDiameter of bob using caliper: d= 2.50cm, 2.40cm, 2.50cmRange of diameters (caliper) = 2.51cm - 2.40cm = .11cmBased on these results, the caliper and the ruler had approximately the same precision.However, based on knowledge of the accuracy of measuring equipment, the calipershould have been shown to be more accurate which therefore proves the presence ofhuman error in collecting data measurements.Thickness of 100g mass using ruler: d= .90cm, .90cm, .90cmRange of diameters (ruler) = .90cm - .90cm = .00cmThickness of 100g mass using caliper: d= .88cm, .87cm, .90cmRange of diameters (caliper) = .90cm - .87cm = .03cmBased on these results the caliper proved to be less precise as the range of thicknesswith the ruler was .00cm which is less than the range of the caliper at .03cm. Again, thisdata doesn’t align properly with the common knowledge that calipers are supposed tobe more precise than rulers but the data we collected was subject to human error andtherefore provided a different result.VI-2Measured values of T in seconds1.581.501.461.441.541.421.491.451.571.421.331.461.301.561.47Average T = 1.466Standard deviation of T, = .0807Standard deviation of the mean of T = = .0208 secondsTherefore T± = 1.47 ± .08VI-3Based on this data:s ± = 7.40 ± .04 g/cmb ±. = -2.47 ± .4 gAndk = (980cm/s^2) (7.3986 g/cm) = 7250.6 g/s^2k ± = 7251 ± 40 g/s^2VI-4s ± = 7.40 ± .04 g/cmb ±. = -2.47 ± .4 gAndk = (980 cm/s^2) (7.3986 g/cm) = 7250.6 g/s^2k ± = 7251 ± 40
