Final answer:
The symptoms of a defective VSS include loss of speedometer functionality, inaccurate speedometer readings, and malfunctioning cruise control. A car's odometer measures distance traveled, and the speedometer measures speed, not velocity.
Step-by-step explanation:
The symptoms of a defective Vehicle Speed Sensor (VSS) include loss of speedometer functionality, inaccurate or erratic speedometer readings, and cruise control not working properly. So, the correct answer to what are the symptoms of a defective VSS is 4) All of the above.
Regarding the additional information provided, a car's odometer measures the distance traveled by a vehicle, not displacement.
Displacement is a vector quantity that includes both magnitude and direction, whereas distance is a scalar quantity representing the total path traveled irrespective of direction.
The speedometer in a car measures speed, which is also a scalar quantity. Speed indicates how fast a vehicle is moving but does not include directional information, whereas velocity is a vector quantity that does include both the speed and direction of an object's motion.
