Directions: Read carefully and analyze each statement. If the underlined word/phrase in each sentence is correct write TRUE. If the word/phrase is incorrect, WRITE THE CORRECT WORD/PHRASE to make the sentence correct. _1. Tycho Brahe gave an accurate measurements of stellar objects and planets before the telescope was even invented. 2. Johannes Kepler discovered a forming new star then published a book which aims to debunk the Aristotelian doctrine of celestial realm. _3. Tycho Brahe proposed the planetary model called heliocentric theory. AS RIC 4. Johannes Kepler used the observations and data of Johannes Kepler to formulate the three laws of motion. _5. Tycho Brahe observed that the orbital path of Mars was elliptical, contrary to the previous astronomers who were trying to fit the planetary paths in circles. 6. According to the law of ellipse formulated by Johannes Kepler, the line joining a planet and the Sun sweeps out equal areas in space in equal intervals of time. _7. The law of harmony explains that the larger the orbit size of a planet the longer it takes to orbit the sun. _8. The orbits of all the planets are circular with the Sun at one focus of the circle. _9. The orbit period of planets is measured in terms of astronomical units or AU. _10. Ptolemy provided the mathematical explanations of the observations of Tycho Brahe.
