18. Based on the results of Experiment 2, one can conclude that the precession rate of a top increases as the stem:
Your Answer is
Correct Answer is G
Explanation
It can be seen from table 2 that as r increases, the compression rate also increases. It can be seen from figure 1 that if the stem becomes longer, r will also become longer. Therefore, it is speculated that the longer the stem, the longer r, so the compression rate increases
