Order of magnitude of a quantity is the ……….., which gives us a value…………. .

Answer

To answer the question regarding the order of magnitude of a quantity, we can break it down into a step-by-step solution:

### Step-by-Step Solution

1. **Understanding Order of Magnitude**:
- The order of magnitude of a quantity refers to a way of quantifying the scale or size of that quantity. It is generally expressed as a power of ten.

2. **Defining the Quantity**:
- A quantity in physics is something that can be measured and has a specific value, such as mass, length, time, etc.

3. **Expressing Order of Magnitude**:
- The order of magnitude is typically expressed in the form of \(10^n\), where \(n\) is an integer. This means that the quantity can be approximated to the nearest power of ten.

4. **Determining the Value**:
- The order of magnitude gives us a value that is closest to the actual value of the quantity being measured. This approximation helps in simplifying calculations and understanding the scale of the quantity.

5. **Conclusion**:
- Therefore, we can conclude that the order of magnitude of a quantity is the power of 10 which gives us the value closest to the actual value of the quantity.

### Final Answer
The order of magnitude of a quantity is the **power of 10**, which gives us a value **closest to the actual value of the quantity**.
