Final answer:
An automatic teller machine (ATM) is an example of using physical capital instead of human capital because it automates the job of a bank teller, utilizing machinery to perform tasks that would traditionally require human labor.
Step-by-step explanation:
Physical capital refers to the amount and kind of machinery and equipment available to help a person produce a good or service. In contrast, human capital refers to the skills, knowledge, and experience possessed by an individual or population, viewed in terms of their value or cost to an organization or country. When machines or technology are used to perform tasks that could otherwise be done by humans, it is an example of substituting physical capital for human capital.
Looking at the provided options, an automatic teller machine (ATM) represents the use of physical capital to get a job done. This is because an ATM automates the tasks of a bank teller, thus minimizing the need for human labor for these transactions.
