What industry did the refrigerated railcar impact the  most?

Meatpacking Industry

Explanation:

The industry that refrigerated rail car impacted the most was Food industry. To be even more specific the meatpacking industry was benefited the most. The industry grew because back then railroads were the primary mode of transportation and were extensively used for delivery of large quantities of meat from processing plants to places all across the country.

Refrigerated rail cars were built in 1857. They were designed with holding areas for ice. The ice blocks were loaded through ports in the roof of a car. Refrigerated cars were twice the cost of traditional rail cars. But on the other hand they allowed food to be transported to the greater distances and to stay fresh longer.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
