Transcribed Image Text:### Educational Content on Dimensional Analysis
#### Dimensional Analysis (Section 2.8)
Using dimensional analysis, convert each of the following measurements to meters:
1. a. 2.7 × 10² nm
2. b. 2.44 km
3. c. 0.0034 pm
4. d. 4.0 × 10⁶ cm
#### Examples and Equivalents:
- 1 gallon = 16 cups
- 1 week = 7 days
- 1 pint = 0.4732 liters
- 1 mile = 5280 feet
#### Practical Applications:
**Problem 2-79:**
- **Topic:** Gastric Juice Production
