The pair containing a scalar quantity and vector quantity is

Options

A. Impulse and Angular momentum
B. work and Frequency
C. Electromotive force and force
D. Electric power and Energy

Answer

To solve the question of identifying a pair containing a scalar quantity and a vector quantity, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand Scalar and Vector Quantities**:
- Scalar quantities have only magnitude (e.g., mass, temperature, energy).
- Vector quantities have both magnitude and direction (e.g., force, velocity, acceleration).

2. **Examine Each Option**:
- **Option 1: Impulse and Angular Momentum**:
- Impulse is a vector quantity (it has both magnitude and direction).
- Angular momentum is also a vector quantity.
- **Conclusion**: This option contains two vector quantities.

- **Option 2: Work and Frequency**:
- Work is a scalar quantity (it has only magnitude).
- Frequency is also a scalar quantity.
- **Conclusion**: This option contains two scalar quantities.

- **Option 3: Electromotive Force and Force**:
- Electromotive force (EMF) is a scalar quantity (it has only magnitude).
- Force is a vector quantity (it has both magnitude and direction).
- **Conclusion**: This option contains one scalar quantity and one vector quantity.

- **Option 4: Electric Power and Energy**:
- Electric power is a scalar quantity (it has only magnitude).
- Energy is also a scalar quantity.
- **Conclusion**: This option contains two scalar quantities.

3. **Identify the Correct Pair**:
- From the analysis, the only option that contains one scalar quantity and one vector quantity is **Option 3: Electromotive Force and Force**.

### Final Answer:
The pair containing a scalar quantity and a vector quantity is **Option 3: Electromotive Force and Force**.
