## Understanding Skin Resistivity and Electrical Safety

The high resistivity of dry skin, approximately \( 5 \times 10^5 \, \Omega \cdot \text{m} \), combined with the 1.5 mm thickness of the skin on your palm can limit the flow of current deeper into the tissues of the body. Suppose a worker accidentally places their palm against an electrified panel. The palm of an adult is approximately a 9 cm × 9 cm square.

### Example Problem

#### Part A

**Question:** What is the approximate resistance of the worker's palm?

**Instruction:** Express your answer with the appropriate units.

**Answer Input:** 
\[ R = \text{Value} \, \text{Units} \]

**Submit Button:** 
To submit your answer, click the "Submit" button.

This information highlights the importance of understanding the electrical properties of human skin, particularly in situations involving potential electrical hazards. Proper knowledge and safety precautions are essential for preventing injuries resulting from electrical contact.
