Now attach the 100 g mass to spring 1. Play the simulator. Using the stopwatch, measure the time for 10 complete cycles, (starting from down, lowest position, and then up, then hitting down again: is an example of one complete cycle). Calculate the measured period by dividing the total time by 10. We will call this value Tz. Pause the simulator. Remove the 100 grams mass from the hook of the spring.

In an experiment, a student measured the volume of a substance while the mass was changed. The student measured up to five kilograms. The graph of the data is plotted below.A volume versus mass graph is shown with mass on the vertical axes from 1 to 10 kilograms and volume on the horizontal axis from 1 to 5 milliliters. A line from the origin through all points and beyond.Which of the following is an error the student made in creating an accurate graph? The axes and graph are based only on measured values. The axes are labeled with the incorrect variables. The plotted points do not show all data collected. The title has the incorrect order for the variables.
