Answer:
C. A quantity that does not indicate direction.
Step-by-step explanation:
There are two types of quantities in physics:
- Scalars: a scalar quantity is a quantity which has only a magnitude, and not a direction.
Examples of scalar quantities are: mass, temperature, time, distance, speed...
- Vectors: a vector quantity is a quantity having both a magnitude and a direction.
Examples of vector quantities are: velocity, displacement, force, acceleration...
Therefore, for the question in the problem:
What is a scalar?
The correct answer is:
C. A quantity that does not indicate direction.
