Question
**Educational Content on Uncertainty in Quantum Mechanics**

**Problem Statement:**
What is the minimum uncertainty in position, in millimeters, of an electron whose velocity is known to be between 2.96×10^5 m/s and 3.08×10^5 m/s?

**Task:**
Express your answer using two significant figures.

**User Input Interface:**
- There is a text box where users can enter their answer. It includes formatting options such as square roots, fractions, and scientific notation for clarity and precision.
- The units for the answer input are in millimeters (mm).

**Current User Input:**
- The user has entered a value of "9.7" mm as their answer.

**Feedback Mechanism:**
- Upon submission, the user received feedback indicating that the answer was incorrect.
- The system provides a prompt: "Incorrect; Try Again; 5 attempts remaining."

**Instructional Guidance:**
To find the minimum uncertainty in position, one can use the Heisenberg Uncertainty Principle, which relates the uncertainties in position (\(\Delta x\)) and velocity (\(\Delta v\)) of a particle:

\[ \Delta x \cdot m \cdot \Delta v \geq \frac{h}{4\pi} \]

where:
- \( \Delta x \) is the uncertainty in position.
- \( m \) is the mass of the electron (\(9.11 \times 10^{-31}\) kg).
- \( \Delta v \) is the uncertainty in velocity (\(3.08 \times 10^5 - 2.96 \times 10^5\) m/s).
- \( h \) is Planck's constant (\(6.626 \times 10^{-34}\) Js).

Use this equation to calculate the minimum uncertainty in position, ensuring the result is in millimeters and expresses the answer to two significant figures.
