what is the diameter of a wire if I have the following readings: 0.46, 0.45, 0.455, 0.455, 0.455 and the uncertainty

To calculate the diameter of the wire, we first find the average of the readings, and then determine the uncertainty.

### 1. Average Diameter:
Given readings:  
0.46, 0.45, 0.455, 0.455, 0.455 (all in mm)

\[
\text{Average Diameter} = \frac{0.46 + 0.45 + 0.455 + 0.455 + 0.455}{5} = 0.455 \, \text{mm}
\]

### 2. Uncertainty:
Uncertainty is often calculated as the **range** (difference between the maximum and minimum values) divided by 2, or alternatively, using the standard deviation. We'll use the range method here.

\[
\text{Range} = 0.46 - 0.45 = 0.01 \, \text{mm}
\]
\[
\text{Uncertainty} = \frac{0.01}{2} = 0.005 \, \text{mm}
\]

### Final Result:
- Diameter = \( 0.455 \pm 0.005 \, \text{mm} \)
