The final evaluation of a DA equation should include which of the following critical steps?
A Identifying the quantity
B Ensuring the desired answer units are the only remaining units
C Estimating the answer
D Checking the conversion factors for correct placement in the numerator and denominator
A Identifying the quantity
B Ensuring the desired answer units are the only remaining units
D Checking the conversion factors for correct placement in the numerator and denominator
The final evaluation of a dimensional analysis (DA) equation should include the following critical steps:
1. Identifying the quantity: This involves understanding what quantity or measurement is being sought.
2. Ensuring the desired answer units are the only remaining units: This step involves canceling out units through appropriate conversion factors, so that only the desired answer units remain in the final result.
3. Estimating the answer: This step involves approximating the final answer based on the information provided and the accuracy needed.
4. Checking the conversion factors for correct placement in the numerator and denominator: This step involves verifying that the conversion factors are correctly placed and used in the equation, ensuring that the units cancel out and the calculation is accurate.
Therefore, the correct answer is A, B, C, and D.
