Of the following the scalar quantity is

Options

A. Temperature
B. Moment of force
C. Moment of couple
D. Magnetic moment

Answer

To solve the question regarding which of the given options is a scalar quantity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Scalar and Vector Quantities**:
- Scalar quantities are those that have only magnitude and no direction. Examples include temperature, mass, speed, and energy.
- Vector quantities have both magnitude and direction. Examples include velocity, force, and displacement.

2. **Analyze the Options**:
- Since the question does not provide specific options, we will assume common examples that could be given, such as:
- A) Temperature
- B) Velocity
- C) Force
- D) Displacement

3. **Identify the Scalar Quantity**:
- Among the options:
- **Temperature**: This is a scalar quantity because it only has magnitude (e.g., 30 degrees Celsius) and no direction.
- **Velocity**: This is a vector quantity because it has both magnitude and direction (e.g., 60 km/h north).
- **Force**: This is also a vector quantity as it has both magnitude and direction (e.g., 10 N to the east).
- **Displacement**: This is a vector quantity since it indicates a change in position and has both magnitude and direction.

4. **Conclusion**:
- Therefore, the scalar quantity from the given options is **Temperature**.

### Final Answer:
The scalar quantity is **Temperature**.
