The answers will be verified as I'm trying to learn from this. This is all the information provided. Thank you very much.Useful quantities: Your Name: 1 Astronomical Unit (AU): 1.51011 m Speed of light: c 3 10 m/s Jupiter's bulk density: pNummer 1.3 g/cm3 Saturn's radius: 6 104 km Saturn's rotation period: 10h A, Multiple-choice questions 12pt for correct answer: no explanation needed] 1. Which of these types of light consists of the most energetic photons? a, Infrared photons b. Visible light photons c, Ultraviolet photons d. All of these photons are equally energetic 2. Which objects in the Solar System obey Kepler's Laws? a. Planets b, Comets c, Asteroids d. All of the above 3. Which of the following properties of the Sun is not a consequence ofits magnetic field a. Granulation b. Sunspots c, Flares d. Coronal mass ejections e. All of these are a consequence of the Sun's magnetic field 4. When is a comet most active (eg, has its largest/longest tail)? a. When it is furthest away from the Sun b. When it is closest to the Sun c. Its activity is the same throughout its orbit d. Its activity varies randomly, with bursts that can occur at any time during its orbit 5. In the current models for the formation of our Solar System, which formed first? a. Terrestrial planets b, Giant planets c, The Moon d. All of these formed at the exact same time 6. What assumption did astronomers in the Antiquity use to explain the retrograde motion of Mars and other outer planets in the geocentric model? a. They assumed that the planets' orbits were elliptical instead of circular b. They that the speed with which planets orbit around the Earth varied over time and could reverse c. They assumed that planets were orbiting on epicycles, ie. circles whose center orbits on another circle centered on the Earth d. They did not try to explain retrograde motion
Explanation / Answer
1) energy of photon = h * f
f is the frequency
for the light with most energetic photons
c) ultra violet photons
2)
as kepler's law is same for all planetery objects
the correct option is d) all of the above
3)
for the following properties ,
the correct option is d) coronal mass ejection
4)
as there is long tail when the speed of asteriod is moving fastest
the correct option is
b) when it is closest to the sun
