a. He doubted Ptolemy's geocentric model because he felt that Ptolemy's special rules for the motion of Mercury and Venus suggested that the Sun should have a more central position b. He believed that the Universe is heliocentric c. He believed that the planets follow circular orbits, but agreed with Ptolemy that the planets must be speeding up and slowing down through space d. He became convinced that he had discovered the correct planetary model when he found that the orbital periods and orbital radii of the planets - which were measured using independent methods - led to the same order of the planets Question 2 Correct Mark 1.00 out of 1.00 Flag question

Question text Why did the planet Mars lead Kepler to the true shape of planetary orbits? Question 2 Answer a. Tycho's data on the path of Mars was the most detailed and complete because, while observing this planet, he developed his method of measuring coordinates several times with different instruments and taking the average b. Tycho's data on the path of Mars was the most detailed and complete because, since it comes closest to Earth, its coordinates can be measured with the greatest accuracy c. Mars' orbit is more circular than the other visible planets d. Mars' orbit is more elongated than the other visible planets e.

Mark 1.00 out of 1.00 Flag question Question text What discovery did Tycho Brahe make about the Great Comet of 1577? Question 6 Answer a. He found that its angular diameter increases and decreases, which proved that it orbits the Sun b. He measured its distance from its parallax, which proved that its orbit is beyond the Moon c. He could not detect its parallax, which proved that comets are not atmospheric phenomena d.

Question 8 Answer a. In this model, a planet’s brightness can change because the planet’s distance from the Earth changes throughout its orbit b. In this model, a planet’s apparent speed can change because the planet is physically speeding up and slowing down in space c. In this model, a planet displays retrograde motion when Earth overtakes it d. In this model, Mercury and Venus have different paths in the sky than Mars, Jupiter and Saturn because Mercury and Venus are between the Earth and Sun Question 9 Correct

Question text Which of the following statements about the planetary model published in Kepler's 'Cosmographic Mystery' is FALSE? Question 12 Answer a. Each planet lies on a circular orbit around one of the 5 perfect solids b. Kepler was initially convinced of its validity because the sizes of the orbits matched the orbital radii from the Copernican model, which was known to predict the paths of planets reasonably well c. It made Tycho aware of Kepler's exceptional geometry skills and convinced him to hire Kepler to help prove that Tycho's planetary data is consistent with the Tychonic system d. It was geocentric because it required the total number of orbiting planets to be 5, thereby excluding Earth
