22) Pendulum Data Mass of bob (g) Length of string (cm) Distance block moved (m) 10 25 1.5 20 25 3.0 30 25 4.5 40 25 6.0 50 25 7.5 Ben and Sam designed a pendulum to move a wooden block. Their first design moved the block about 1.5 meters. Ben hypothesized that the weight of the pendulum bob was directly linked to how far the block moved. Sam hypothesized that the length of the string attached to the bob was the factor directly linked to the block's movement. To test these hypotheses, the two students decide that they must conduct an experiment. The results of the experiment they ran are shown in the table. Ben claims that they show that his hypothesis is right, but Sam claims another experiment is needed. An experiment that tests Sam's hypothesis must include A) pendulum bobs with equal weights and pendulums with different lengths of string. B) pendulum bobs with equal weights as well as pendulums with strings of equal length. C) pendulum bobs with different weights as well as pendulums with strings of equal length. D) pendulum bobs with different weights as well as pendulums with different lengths of string.
