The choice that represents velocity is 35 m/s.
The choice that represents velocity is: 35 m/s.
Velocity is a vector quantity that indicates the rate at which an object changes its position. It has both magnitude (how fast an object is moving) and direction.
To identify velocity among the given options, we need to look for a quantity that includes both a magnitude and a direction.
- Option 1, "4 g/mL," does not represent velocity because it only provides the magnitude (4 g/mL) without any direction.
- Option 2, "12 m/s2," represents acceleration rather than velocity. The units "m/s2" indicate the rate at which an object's velocity changes over time, which is acceleration.
- Option 3, "15 km/hr west," correctly represents velocity. It provides both a magnitude (15 km/hr) and a direction (west). However, this is not one of the given options, so it is not the correct answer.
- Option 4, "35 m/s," represents velocity. It includes the magnitude (35 m/s) without a direction.
Therefore, the choice that represents velocity is 35 m/s.
