A group of students must conduct an experiment to determine how the location of an applied force on a classroom door affects the
rotational motion of the door. The rotational inertia of the door about its hinges is known. The initial angular velocity of the door is zero. Which of the following lists what measuring devices the students need and the measurements they should take to collect the necessary data to test the relationship between a torque exerted on the door and the change in angular velocity of that object about the hinges of the door? A. A protractor to measure the angular displacement of the door and a meter stick to measure the radial distance from the door's hinges to the location where the force is applied.
B. A stopwatch to measure the time interval during which the force is applied and a meter stick to measure the radial distance from the door's hinges to the location where the force is applied
C. A force probe to measure the applied force on the door, and a stopwatch to measure the time interval during which the force is applied, and a meter stick to measure the radial distance from the door's hinges to the location where the force is applied.
D. A stopwatch to measure the time interval during which the force is applied, a force probe to measure the applied force on the door, a protractor to measure the angular displacement of the door, and a meter stick to measure the radial distance from the door's hinges to the location where the force is applied.
The correct answer among all the other choices is 4. This is the number of the lowest energy level that contains an f sublevel. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
