ttl 19). This is due to earth’s radii changes caused by both altitude and latitude variations as one moves to the poles whereby distance to the crust continues to decrease. This is because at the poles the surface is flattened compared to the equator where there is bulging due to a large radius, which is the reason behind an individual’s location being the determinant of g. In quest to find g, this experiment utilizes the following formula, T = 2? / ? = 2? v (L/g) = 2? v (L/g) by rearranging g = 2?L / T2 Methodology Experiment Materials required Piece of string, which is lighter such that its weight is negligible Hook Pendulum or bob Stopwatch Meter rule or tape measure Supporting board for hook Steps to perform experiment The first step entailed setting up the experiment. This is by hanging pendulum or bob using a string from the supporting board where there is a hook, then adjusting L to approximately 50cm or appropriate length that will act as the initial value. Then displacement of a pendulum using a certain angle before released to swing back and forth took place. It was essential to ensure motion in this case was vertical instead of erratic elliptical, which mostly develops due to inappropriate displacement. Timing was at intervals of 10 oscillations for each chosen L until it reached about 125cm and having at intervals of 15cm, then tabulating obtained data. Data values were L, T and angles. After tabulation, calculation commenced to ascertain T2 and g values. Recording of data included g and its mean values besides standard error deviations. The last step encompassed plotting of L vs. T2 graph with the intention of ascertaining its slope, which was the value for g (Serway, Jewett & Vahe? 465). Results Table 1: Data Results L (M) T50 (S) T (S) T (S) T (S) T (S) T2 (S2) g (M/S2) 50 65 80 95 110 Discussion Formula and effects on experimental accuracy Based on the experimental results, error in L prompts a linear relation error in any resulting value of g. This implies suppose there was a 10% error in value of l, it will reflect an erratic value of g having a margin of 10%. In addition, an error in g exhibited a squared or parabolic relationship with error evident in the value of T. Suppose T had an error bearing a margin of 10%, this will reflect 21% value of g. This is because 1.10 x 1.10 = 1.21 Controlling and measuring length String used in this experiment was light together with heavy mass. The purpose of the latter was to ensure the center of pendulum’s oscillation system was as close as possible to the center of the mass of fishing sinker. Then calculating mass of the string compared to that of the sinker commenced. There was also a need to increase the length of the string to ensure less percentage error restricted by 8m measuring tape (stairs were approximately 15m high). Accuracy’s margin was set at ±5 or approximately 0.07% over 7.5m. It entailed one hour to wait for effective completion of string’s stretch and twist caused by the suspended mass, which was a lot of time. To rectify this problem in the next experiment, it would be essential to use a light string as well as measuring stretch before starting. Calculation of maximum centripetal acceleration commenced with the aid of angle created by pendulum (where PE converted to KE). However, this affected both string and accuracy of the data due to unknown stretch ...Show more

Determining the density of an irregular solid
Challenge to the determination of the density of an irregular solid is poised to its non-conformity to the any three-dimensional object that are used in the functional determination of the volume of natural and synthetic three dimensional objects. An irregular object falls outside the circular, ellipse, triangular, square, and rectangular or sphere basic units used in the mathematical computation of object.
