Depending on how far the source where the signal is coming from is, radio waves travel at the speed of light. If the civilization lives in a star system that is 20 light years away from us, the signal would take 20 light years to reach us.

(1 light year = 1 normal year but traveling or moving at the speed of light).

PLEASE ANSWER SOON!!! How has a diverse population made a positive impact on the United States? I need a couple sentences!!
Akimi4 [234]

Answer:

So a diverse population in the United States has greatly impacted the relationships with other countries, has given more jobs so that means better economy, and has made other countries more united like the United States.

So my first one was that the United States has better relationships with other countries. This has been shown many time, like when the soviet union had fallen apart the United States had bought rockets from Russia and they also did this because they saw that people were being tread nice over here so that further the trust with the two nations. Another example I gave was they gave more jobs. If you have people who can speak more than one language then you can send them over seas and they can talk to business and make money over seas making a better economy for both of the nations. Finally more and more nations want to have freedom like the U.S. this is a great role model in the world and many countries want to be like us so this is an overall great example because we are the role model for the world.

  • Setting events

<h3>What are setting events?</h3>

Setting events are those factors that set the stage for a chain reaction. Setting events play a big part in the reaction or behavior of a person.

For instance, if a business owner quarrels with his or her partner before coming to work, this might cause a bad disposition that will set the stage for a host of other bad things that will occur during the day.

So, the quarrel was in operation before the display of outbursts on an employee and is, therefore, related to the behavior.
