Which choice represents velocity?(1 point) Responses 4 g/mL 4 g/mL 12 m/s2 12 m/s2 15 km/hr west 15 km/hr west 35 m/s
15 km/hr west
Among the given choices, the choice that represents velocity is:
35 m/s
Velocity is a physical quantity that represents the rate at which an object changes its position. It not only includes the speed of the object but also the direction in which it is moving. In the list of choices provided, the option that represents velocity is "15 km/hr west."
To determine if a quantity represents velocity, you need to check if it includes both speed and direction. In this case, the given option includes a magnitude (15 km/hr) indicating the speed and a direction (west) indicating the object's movement. Therefore, "15 km/hr west" correctly represents velocity.
It's important to note that velocity is a vector quantity, meaning it has both magnitude and direction. Magnitude refers to the quantity or value, while direction indicates the object's motion.
