What is the flaw with using apparent brightness rather than absolute brightness to determine the brightness of a star?

Apparent brightness does not use the star's color or temperature.

Apparent brightness does not take into account the distance of the star from Earth

Apparent brightness is only theoretical, its value cannot be directly measured with equipment

Apparent brightness is only on a comparative scale that determines how bright a star looks from a theoretical distance of 10 parsecs
from Earth.

Don’t answer if you’re just going to put a link or file.

The three basic economic questions societies face are (1) what goods and services to produce, (2) how to produce those goods and services, and (3) who will get them.

In one or two paragraphs, explain how supply and demand help societies determine their answers to these three questions. Be sure to provide an example of the effect of supply and demand on a society's answers.

please help

Answers

When supply is high is the people don’t want it as much. When the supply is low people most likely want It. Demand is just basically controlled by the people.

Supply and demand let's us know what needs to be more produced and what needs to be less produced. For example, the demand for a TV will be high, but the demand for paper might be low. So the company will produce more TVs and less paper because the Supply and demand tells them that the people want TVs. When supply is high the people don’t want it as much but the supply is low people most likely want It. Demand is just basically controlled by the people.
