astronomy 1010 final exam gsu; GRADED A+

you are in tuscon, arizona, at 32 degrees north latitude & 111 degrees west longitude. What is the altitude of the North Star? correct answers C. 32 degrees above the horizon The Sun's apparent annual motion around the ecliptic, at a rate of 1 degree per day against the stars, is caused by what actual motion of the Earth? correct answers A. Revolution around the Sun in principle, you could learn the circumference of the Earth, by measuring how far... correct answers B. you would have to walk to have the North Star one degree higher in the sky suppose an inferior planet orbits the Sun in 8 months, while Earth, requires 12 months. How often does the inferior planet "gain a lap" on us? (time between inferior conjunctions) correct answers B. 24 months galileo saw that the disk of Venus changed size and phase. What would he have observed for venus just before or after venus passed between us and the Sun? correct answers C. a relatively larger diameter disk in a crescent phase what is the average distance from the Sun of an object which takes 3 years to complete one orbit? correct answers C. slightly more than 2 AU newton discovered the force on a planet that was required to explain its orbital motion. What was the direction of this force? correct answers B. inward, pointed towards the Sun. which of these has the longest wavelength? correct answers D. infrared radiation from your classmates the sun's thermal energy output peaks in the visible part of the spectrum. compared to this, what would describe the thermal radiation from a cooler star? correct answers D. less total energy with a peak in the infrared in hydrogen, an electron changing fro the first to the second orbital energy level would account for what spectral line? correct answers B. an absorption at an ultraviolet wavelength a 10-inch aperture telescope would be a large telescope size for amateurs. how many times more light is gathered by the Palomar 200-in telescope? correct answers D. 400 which of these describes diffraction? correct answers B. the spreading of a light beam after it passes through an opening which describes the wavelengths of radiation form astronomical objects which can be detected by telescopes on Earth's surface? correct answers A. visible wavelengths (400-700 nm) & radio wavelengths greater than 1 mm
