Answer to Question #294075 in Physics for Bemskies

Question

in an experiment to measure the height of a ceiling, a pendulum bob was suspended from the ceiling so that the initial height h of the bob from the floor was 20cm. at this height, the bob was displaced and set into oscillation. the time for 20 oscillations was determined and recorded, this was repeated once and the average time t for 20 oscillations and hence, the period of oscillation t was calculated. the experiment was repeated for different heights of the bob from the floor and in each case the corresponding values of h,t1 and t2 was recorded and shown below. h(cm)= 20.00, 40.00, 60.00, 80.00, 100.00. t1= 46.30, 41.85, 37.95, 33.20, 28.85. and t2= 46.00, 41.95, 38.00, 33.35, 28.95. draw a table showing the corresponding values of h, t, t and t²

Answer 1

Draw a table showing the corresponding values of h, t, t and t²:
