Question

Distance and mass are the example of :

• A. Scalar Quantity
• B. Vector Quantity
• C. Equator Quantity
• D. Parallel Quantity

Hint:

Scalar quantities have only magnitude, whereas vector quantities have both magnitude and direction.

Answer 1

The Correct Option is A

Concept: Physical quantities are classified into two main categories:
• Scalar quantities -- quantities that have only magnitude
• Vector quantities -- quantities that have both magnitude and direction Distance and mass possess only magnitude and do not require direction for their description. Therefore, they are scalar quantities.

Step 1: Understand scalar quantities.
A scalar quantity is completely described by its numerical value and unit only. Examples: \[ \text{Mass, Distance, Time, Speed} \]

Step 2: Classify the given quantities.
Both distance and mass have magnitude only and no direction. Hence, they are: \[ \text{Scalar Quantities} \] Therefore, the correct answer is: \[ \boxed{(A)\ \text{Scalar Quantity}} \]
