Why did it take Kepler so many extra years to determine the elliptical orbits of the planets? a. he presumed copernicus was correct

b. he inferred the orbits were circular

c. incorrect prior knowledge can delay good reasoning

d. he presumed copernicus was incorrect

b. he inferred the orbits were circular

Explanation:

Johannes Kepler was a German astrologer and astronomer who, successfully, defined the orbit. According to his first law, the planets moved in elliptical orbits. However, before this, he believed that the universe was circular just as Copernicus did. In this sense, he also thought that the orbits of the planets were circular. Later did he realize the truth after observing the movements of the planets in relation to their distances from the Sun and the total amount of time needed to complete their revolutions around it.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
