Question 19 A student conducts an experiment to test the relationship between the net torque exerted on an object and the change in angular momentum of the object. A variable net torque is exerted on the object to make it rotate about its internal axis. Data from the experiment are used to construct a graph of the net torque exerted on the object as a function of time, as shown in Figure 1. A graph is also created of the angular momentum of the object as a function of time, as shown in Figure 2. Which of the following statements about the change in the object's angular momentum for a given time interval is correct? Justify your selection. :: Net Torque (Nem) : Po i 2 7 8 9 10 3 4 5 6 Time (s) Figure 1 Argul Momentum Fiore The change in the object's angular momentum for a given time interval remains the same throughout the experiment. This is because the slope of the best-fit line in Figure 1 is constant. i Submit

Figure 1 Angular Momentum Web Times Figure 2 CA The change in the object's angular momentum for a given time interval remains the same throughout the experiment. This is because the slope of the best-fit line in Figure 1 is constant. The change in the object's angular momentum for a given time interval remains the same throughout the experiment. This is because the net torque and angular momentum increase in Figure 1 and Figure 2, respectively. The change in the object's angular momentum for a given time interval does not remain the same throughout the experiment. This is because the slope of the best-fit line in Figure 1 is a nonzero constant The change in the object's angular momentum for a given time interval does not remain the same throughout the experiment. This is because the net torque is nonzero in Figure 1. Submit
