Answer

Explanation:

Step1: Recall metric - prefix relationship

The prefix "kilo -" means 1000. So 1 kilometer is 1000 meters.

Step2: Analyze importance of conversion factors

In dimensional analysis, conversion factors are used to change units. Their main purpose is to ensure the final answer has the desired units.

Answer:

Question 13: A. 1 km = 1000 m Question 14: A. They ensure the final answer has the desired units
