QUIZ 3
Question 1
In the epicycle model of the Universe the Sun can be found: on a deferent between Venus and Mars. at the center of the Solar System, on a janky wire hanging from the sky. on an epicycle between Venus and Mars. Question 2
According to the geocentric view, everything in the heavens had to go around the Earth, which was the center of the universe. What objects did Galileo discover with his telescope that clearly didn't go around the Earth? moons around the planet Jupiter. a ring around the Sun. stars in the Milky Way that just kept going in a straight line. the Earth's Moon. Question 3
Which of the following was NOT done by Galileo Galilei? Observe sunspots on the Sun. Discovering that Venus goes through phases (like the Moon). Discovering four large moons around Jupiter. Inventing the telescope. Question 4
The scientist who formulated the three laws of planetary motion by analyzing the data on the precise location of planets in the sky was: Tycho Brahe Johannes Kepler J. C. Adams Galileo Galilei
Question 5
Which person below wrote On the Revolution of the Celestial Orbs?
Ptolemy Copernicus Brahe Nancy Drew Question 6
Which of the following is not contributed to Tycho Brahe? Claiming the Sun was at the center of the Universe. Observations of Mars. Finding the parallax of a comet. Observation of a supernova. Question 7
What specific event really made it possible for the three laws of planetary motion to be discovered? a brilliant comet in 1601 blazed across the sky and was seen to cross in front of Venus. Galileo's books were published in Danish and became widely available to the public. an alignment of all the known planets in one part of the sky called everyone's attention to them. Tycho Brahe died and his assistant was able to get full access to his data.
Question 8
What law state's that a planets orbital speed varies such that equal areas occur in equal time periods? Kepler's Second Law Kepler's First Law The Bob Loblaw Law Kepler's Third Law Question 9
When Copernicus first created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model. Why not? Copernicus placed the planets in the wrong order going outward from the Sun. Copernicus misjudged the distances between the planets. Copernicus used perfect circles for the orbits of the planets, whereas planets actually have elliptical orbits. Copernicus placed the Sun at the center but did not realize that the Moon orbits Earth. Question 10
In what book did Ptolemy describe his epicycle model of the Universe? Lord of the Rings On the Revolution of the Celestial Orbs Dialogue Concerning the Two Major Bodies Almagest
