Which of the following actions are minimally necessary to determine if a motion detector should be calibrated before using it to investigate the motion of an object? Note: Even if you did not use a motion detector in to carry out this experiment, consider the information in the reading when responding to this question. @ Measure the position of an object without using the motion detector, and see if the motion delector identifies the same position. O Measure the velocity of an object without using the motion detector, and see If the motion detector identifies the same velocity. Both of these actions are required; neither is sufficient by itself. ONeither of these actions are required; no additional measurements are needed for calibration
