Explain why the research supervisor’s concerns in the following scenario are unfounded. Remember to use language appropriate for the situation. Situation: Dana is working with Mackenzie, a new research supervisor at a teaching hospital. Mackenzie is unhappy with the most recent research proposal from the medical department, which will study the usefulness of a new diabetes treatment by tracking its effects on a small group of specially chosen patients. She tells Dana that the research will reflect poorly on the hospital because it will not be reproducible or generalizable.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
