Pendulum Problems ACTIVITY 1: Copy and paste the example problem and the steps‚ so that the steps are in the correct order into a new Word document and upload it to Moodle. Example Problem 1: A hypnotist swings her watch from 20.0cm chain in front of a subject’s eyes. What is the period of the swing of the watch. Thus‚ we see that the pendulum used by the hypnotist has a period of 0.898s. | Before we can use this formula‚ however‚ we must ensure all our variables are in the correct units.

Using the Logger Pro‚ the kinetic and potential energies of a ball in free fall were graphed and compared. At the end of the experiment‚ it was said that member #2 was the most “powerful” among the group since she had the highest power output both in going up and going down the stairs and in the second activity‚ the

First of all‚ it is said in the passage that the stone balls were being used as a weapon. However‚ the listening argues that there has no cracks and breaking pieces on the stone balls. If the stone balls was used as a weapon‚ there must be some cracks on the balls while they throw them to the targets‚ but it turns out that these balls were well preserved
