The energy required to raise a given volume of water from a well can be

Options

A. mega watts
B. mega newton
C. megajoules
D. kilo watts

Answer

To solve the question regarding the energy required to raise a given volume of water from a well, we need to identify the correct unit of energy from the options provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the unit of energy required to raise a volume of water from a well.

2. **Identifying the Options**: The options given are:
- Option 1: Megawatt
- Option 2: Mega Newton
- Option 3: Mega Joule
- Option 4: Kilowatt

3. **Analyzing Each Option**:
- **Option 1: Megawatt**: This is a unit of power, not energy. Power is the rate at which energy is used or transferred. Therefore, this option is incorrect.
- **Option 2: Mega Newton**: This is a unit of force. Newton is a measure of force, not energy. Hence, this option is also incorrect.
- **Option 3: Mega Joule**: This is a unit of energy. The joule is the standard unit of energy in the International System of Units (SI). Therefore, this option is correct.
- **Option 4: Kilowatt**: This is another unit of power, similar to megawatt. It measures the rate of energy transfer. Thus, this option is incorrect.

4. **Conclusion**: Since we are looking for a unit of energy, the correct answer is **Option 3: Mega Joule**.

### Final Answer:
The energy required to raise a given volume of water from a well can be measured in **Mega Joule**.
