**The Sum of 130 mW and 1.50 W: A Mathematical Analysis**

Introduction

In this article, we will delve into the world of mathematics, specifically focusing on the concept of unit conversion and addition of powers. The question at hand is to find the sum of 130 milliwatts (mW) and 1.50 watts (W). This seemingly simple problem requires a thorough understanding of the units involved and the correct application of mathematical operations.

Understanding the Units

Before we proceed with the calculation, it is essential to understand the units involved. A watt (W) is a unit of power, defined as one joule per second. On the other hand, a milliwatt (mW) is one-thousandth of a watt, or 0.001 W. To add these two values, we need to ensure that they are expressed in the same unit.

Converting Milliwatts to Watts

To convert 130 mW to watts, we can use the conversion factor: 1 mW = 0.001 W. Multiplying 130 mW by this conversion factor, we get:

130 mW × 0.001 W/mW = 0.13 W

Now that we have both values in watts, we can proceed with the addition.

Adding 0.13 W and 1.50 W

To add 0.13 W and 1.50 W, we can simply add the two numbers:

0.13 W + 1.50 W = 1.63 W

Therefore, the sum of 130 mW and 1.50 W is 1.63 W.

Conclusion

In conclusion, the sum of 130 mW and 1.50 W is 1.63 W. This problem may seem trivial, but it highlights the importance of understanding unit conversion and the correct application of mathematical operations. By following the steps outlined in this article, we can ensure accurate results and avoid common pitfalls.

Answer

The correct answer is A. 1.63.

Introduction

In our previous article, we explored the concept of unit conversion and addition of powers to find the sum of 130 milliwatts (mW) and 1.50 watts (W). In this article, we will delve into a Q&A session to address some of the most frequently asked questions related to this topic.

Q&A Session

Q: What is the difference between watts and milliwatts?

A: A watt (W) is a unit of power, defined as one joule per second. On the other hand, a milliwatt (mW) is one-thousandth of a watt, or 0.001 W. This means that 1 W is equal to 1000 mW.

Q: How do I convert milliwatts to watts?

A: To convert milliwatts to watts, you can use the conversion factor: 1 mW = 0.001 W. Simply multiply the value in milliwatts by 0.001 to get the equivalent value in watts.

Q: What is the sum of 130 mW and 1.50 W?

A: To find the sum of 130 mW and 1.50 W, we need to convert the milliwatts to watts first. Using the conversion factor, we get:

130 mW × 0.001 W/mW = 0.13 W

Now that we have both values in watts, we can proceed with the addition:

0.13 W + 1.50 W = 1.63 W

Therefore, the sum of 130 mW and 1.50 W is 1.63 W.

Q: Can I add milliwatts and watts directly?

A: No, you cannot add milliwatts and watts directly. This is because they are different units of power, and adding them would result in an incorrect answer. To add milliwatts and watts, you need to convert the milliwatts to watts first.

Q: What are some common applications of watts and milliwatts?

A: Watts and milliwatts are commonly used in various applications, including:

Power consumption of electronic devices
Energy efficiency of appliances
Power output of motors and generators
Energy storage in batteries

Q: How do I choose the right unit of power for my application?

A: To choose the right unit of power for your application, consider the following factors:

The magnitude of the power value: If the power value is very small, milliwatts may be a more suitable unit. If the power value is very large, watts may be a more suitable unit.
The precision required: If you need to measure power values with high precision, watts may be a more suitable unit.
The convenience of calculation: If you need to perform calculations involving power values, watts may be a more convenient unit.
