Astronauts visiting Planet X have a 250-cm-long string whose mass is 5.00 g. They tie the string to a support, stretch it horizontally over a pulley 2.00 m away, and hang a 4.00 kg mass on the free end. Then the astronauts begin to excite standing waves on the horizontal portion of the string. Their data are as follows: | m | Frequency (Hz) | |---|----------------| | 1 | 31 | | 2 | 66 | | 3 | 95 | | 4 | 130 | | 5 | 162 | Use the best-fit line of an appropriate graph to determine the value of g, the free-fall acceleration on Planet X.
