When the ends of the bottomruler are displaced in opposite directions, in a horizontal plane, the bottom ruleroscillates with simple harmonic motion.A student conducts an experiment to investigate the relationship between the timeperiod, T  , of the suspended oscillating ruler, and the distance, d  .The student’s results are shown in the table.4 Section B Answer all the questions in the spaces provided. d   /mtime for 20 oscillations/smean timeperiod T   /slog 10 ( T   /s)log 10 ( d   /m)reading 1reading 2reading 3 0.800 20.20 20.38 20.02 1.01 0.0043 –0.0970.700 23.52 23.16 23.28 1.17 0.0681 –0.1550.600 27.26 25.92 27.30 1.34 0.127 –0.2220.500 32.44 32.23 32.65 1.62 0.210 –0.3010.400 41.41 41.15 41.33 2.07 0.316 –0.3980.300 54.02 53.89 53.820.200 80.82 80.91 80.67 vertical stringsof fixed lengthaxis of oscillationis indicated by thedotted linefixedrulerABoscillatingruler d
