To determine which of the given quantities is considered a vector, let's analyze the properties of each option:
A. Temperature:
- Temperature is a scalar quantity because it only has magnitude and no direction.
B. Velocity:
- Velocity is a vector quantity because it has both magnitude (speed) and direction.
C. Mass:
- Mass is a scalar quantity as it only has magnitude and no associated direction.
D. Time:
- Time is also a scalar quantity since it only has magnitude and no direction.
Given the properties above, the best answer to the question is:
B. Velocity
Velocity is considered a vector because it includes both magnitude and direction.
