Options

A. impulse, pressure and area
B. impulse and area
C. area and gravitational potential
D. impulse and pressure

Explanation

To determine which of the given quantities are vector quantities, we will analyze each one based on the definitions of vector and scalar quantities. A vector quantity has both magnitude and direction, while a scalar quantity has only magnitude.

### Step-by-Step Solution:

1. **Identify the quantities**: The quantities given are pressure, power, energy, impulse, gravitational potential, electrical charge, temperature, and area.

2. **Analyze each quantity**:
- **Pressure**: Pressure is defined as force per unit area. It has magnitude but no specific direction associated with it. Therefore, pressure is a scalar quantity.
- **Power**: Power is the rate at which work is done or energy is transferred. It has magnitude but no direction. Thus, power is a scalar quantity.
- **Energy**: Energy is the capacity to do work. It is measured in joules and has magnitude only. Therefore, energy is a scalar quantity.
- **Impulse**: Impulse is defined as the change in momentum of an object when a force is applied over time. It has both magnitude and direction, making it a vector quantity.
- **Gravitational Potential**: Gravitational potential is related to the position of an object in a gravitational field and is a form of energy. It has only magnitude and is therefore a scalar quantity.
- **Electrical Charge**: Electrical charge is a property of matter that causes it to experience a force when placed in an electromagnetic field. It has magnitude only and is a scalar quantity.
- **Temperature**: Temperature is a measure of the average kinetic energy of particles in a substance. It has magnitude only and is a scalar quantity.
- **Area**: Area is a measure of the extent of a surface in two dimensions. While it can be represented as having direction (normal to the surface), it is primarily considered a vector quantity because it can be added according to vector rules.

3. **Conclusion**: After analyzing all the quantities, we find that the only vector quantities among the given options are **impulse** and **area**.

### Final Answer:
The only vector quantities among the given options are **impulse** and **area**.
