To determine which of the following is a scalar quantity, you need to understand the definition of scalar and vector quantities. A scalar quantity is a quantity that has only magnitude, while a vector quantity is a quantity that has both magnitude and direction.
Looking at the given options:
1. Acceleration - Acceleration is a vector quantity because it has both magnitude (how much an object's velocity changes) and direction (the direction of change in velocity).
2. Speed - Speed is a scalar quantity because it only refers to how fast an object is moving without considering its direction.
3. Velocity - Velocity is a vector quantity because it includes both the speed and direction of an object's motion.
4. Displacement - Displacement is a vector quantity because it represents the change in position of an object considering both magnitude and direction.
Based on the definitions, the scalar quantity among the given options is speed.
