Based on the data below: 1. How did the change in radius, while keeping everything constant, affect the stopper as it was spinning? 2. How did the increase in mass (number of stoppers), while keeping everything constant, affect the stopper as it was spinning? 3. How did the change in hanging mass (m2), while keeping everything constant, affect the stopper as it was spinning?
