The two most important intrinsic properties used to classify stars are luminosity and temperature. Luminosity refers to the amount of energy a star emits per second and is usually measured in units of watts or solar luminosities. Temperature, on the other hand, is a measure of the star's surface temperature and is usually expressed in Kelvin.
These two properties are used to place stars on the Hertzsprung-Russell (HR) diagram, a graphical representation of the relationship between a star's temperature and luminosity. This diagram allows astronomers to classify stars into different types, including main sequence stars, giants, and supergiants.
Luminosity and temperature are also used to determine a star's spectral class, which is based on the star's chemical composition and the lines in its spectrum. This information can provide insights into the star's age, mass, and evolutionary stage.
Overall, luminosity and temperature are critical intrinsic properties used to classify stars and provide a foundation for understanding their characteristics and behaviors.

Why does the United States have a long history of opposition to Communist ideals?
Answer:
I think there are two major reasons that the U.S. was afraid of the spread of communism: 1) The U.S. was committed to democracy and "self-determination," or the right of citizens to determine their own form of government.

Why did the Wheatfield decision have such a long standing impact?
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The Wheatfield decision had such a long-standing impact because it transcended the test of time and today we can see the consequences of climate change on the planet.
When Artist Agnes Denes presented his artwork "Wheatfield-A Confrontation" in 1982, she planted a two-acre field of grain in New York City. At the back of this field were the skyscrapers of the city.
This was meaningful because the artists tried to send the message that large urbanization, concrete, and steel, were a major risk for the soil, agriculture, and the land.
And as we see today, she was right and the meaning is that 30 years later, climate change is a major concern on planet earth and governments are trying to reach agreements to minimize the consequences of global warming.
