1) Compute the travel time ratio of the other objects to the hollow cylinder. 2) Discuss how the travel time ratio of solid cylinder to hollow cylinder have confirmed or contradicted the theoretical value. 3) Determine whether the billiard ball/racquetball is solid or hollow. 4) Discuss the object with the largest SEOM. 5) Discuss possible systematic errors in the measurement.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
