Which choice represents velocity?(1 point) Responses 35 m/s 35 m/s 4 g/mL 4 g/mL 15 km/hr west 15 km/hr west 12 m/s2 12 m/s2
The choice 35 m/s represents velocity.
The choice that represents velocity is: 15 km/hr west.
The choice that represents velocity is "15 km/hr west."
Velocity is a vector quantity that measures the rate of change of an object's displacement with respect to time. It has both magnitude (speed) and direction. In this case, the magnitude of the velocity is "15 km/hr," indicating the speed of the object, and the direction is "west," indicating the direction in which the object is moving.
When looking at the other choices:
- "35 m/s" represents speed but does not specify a direction, so it is not velocity.
- "4 g/mL" represents density, which is a completely different quantity unrelated to velocity.
- "12 m/s2" represents acceleration, which measures the rate of change of velocity, but it is not velocity itself.
Therefore, "15 km/hr west" is the only choice that represents velocity.
