Our experiment is based on the best value for acceleration of gravity (g), by using experimental data from literature review p exp 0.1 0.3 0.5 time 0.15 0.25 0.32 0.39 0.45 0.7 1 We assumed our parameter (g) and then we applied the following equation to calculate the new density: pcal. = 0.5 * g * (time) 2 Find the exact value of g by least square method on excel Select one: a. 9.645 b. 9.217 c. 10.114 20/20 d. 10.921
