ASTR 2003-Survey of the Universe Test no.1 – The Solar System September 21, 2010 Answer all of the following 50 questions on a blue letter sized scantron “General Purpose Scantron Answer Sheet form no. 4521” using a #2 pencil. Make sure that your Full Name and Student ID Number are on the answer sheet and that all answers are recorded in the correct position. Each question is worth 1 point. This is a closed-book, closed-note exam and you have approximately 80 minutes to complete it. Afterwards hand in your scantron with your answers and take this test home with you. You may (optionally) return another completed scantron to class on Thursday after retaking the test at home using your books and notes. Your final score will be the average of the test and retest (or the test alone if that is greater). Qs. 1-6 Each of the following 6 questions may be answered by one of these distances a. Light Year b. Astronomical Unit c. Radius of the Sun d. Radius of the Earth e. 1 mile 1. Which of these distances best describes the scale of the Solar System? b 2. Which of these distances best describes the scale of the distances to nearby stars in the Milky Way Galaxy? a 3. Which of these distances best describes the size of Venus? d 4.

Nevertheless is was still difficult to explain physically why objects stayed with the Earth as it orbited the Sun, and why we are attracted to the center of the Earth. A new foundation for physics, introducing the concepts of inertia and a better understanding of gravity, was laid by ----- a ---.(Q. 10) Finally ----- d ----(Q. 11) synthesized all of this work into a new mathematical unification of physics and astronomy, incorporated in three laws of motion and a universal law of gravity. Fill in the blanks from the following list of historical figures: a. Galileo Galilei b. Nicolai Copernicus c. Tycho Brahe d. Isaac Newton e. Johannes Kepler 12.
