GPT 3.5
Limitations of dimension analysis:
1. It assumes that all physical quantities involved are linearly dependent, which may not always be the case.
2. It cannot be used to determine numerical constants in equations.
3. It may not be accurate for complex systems with multiple interacting variables.
Uses of dimension analysis:
1. Checking the consistency of mathematical equations by verifying that the dimensions on both sides of the equation match.
2. Estimating physical quantities in the absence of experimental data.
3. Simplifying and deriving relationships between physical quantities in various fields such as physics, engineering, and chemistry.
