006 (part 1 or 2) 10.0 points A student sits on a rotating stool holding two 1 kg objects. When his arms are extended horizontally, the objects are 0.8 m from the axis of rotation, and he rotates with angular speed of $0.68rad/sec$ . The moment of iner- tia of the student plus the stool is $5kgm^{2}$ and is assumed to be constant. The student

6. You are making great progress! You have calculated that it takes a sound wave Q.2326 seconds to travel from the speaker to Max. Next, you need to measure the delay between when Emma claps and when Max claps and compare them. You'll use the stopwatch tool on the slow motion video on the left. Measure the time on the stopwatch when Emma claps. Show me how! $\square $ The answer to this question depends on your answers to previous questions. Schrut Answer 0/ me submissions used
