Chapter 22, Problem 2SOP
Saturn is about 60,000 km in radius, and its rings are only about 0.01 km thick with ripples 100 m high. Design a really big model with Saturn 60 inches in radius (10 ft in diameter). How thick must the rings be in your model and how high can the ripples be? A sheet of paper is about 0.004 inches thick.

You are making a scale model to visualize the relative sizes of the planets in our solar system. The scale of the model is: 1 cm = 2000 km. The radius of Saturn is 60,000 km. At what radius will Saturn appear on your scale model?
You decide to go on an interstellar mission to explore some of the newly discovered extrasolar
planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are
five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From
your observations of these planets, you collect the following data:

The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this?
Group of answer choices
You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet.
You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth.
On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…

- You are a rover pilot on the crew of the initial exploration team sent to Kepler 22b,the first extrasolar planet discovered within the habitable zone of a sun-like star. Thescience team recently discovered liquid water on the surface. (Hurrah!) Your rover isat point A on the shore of a circular lake with radius 4 km collecting samples. Thescience team wants to send your rover to a point C diametrically opposite A. Therover can drive around the circumference of the lake at a rate of 4 km per hour andfly over the lake at a rate of 3 km per hour.(a) How long will it take the rover to fly across the lake?(b) How long will it take the rover to drive around the shore of the lake?You could also fly at an angle θ along a chord inside the circular lake, andcomplete the rest of the path driving along the circumference of the lake.(c) Find the length of the chord in terms of θ.

If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. The reason astronomers want telescopes with large primary mirrors is to gather as much light as possible. In crown glass, the index of refraction for red light is 1.512 and for yellow light it is 1.518. Thus in crown glass, red light is slower than yellow light. If the axes of two polarizers are anti-parallel to each other, then no light will get through. The glasses for nearsighted people create real images for them to see. The larger the diameter of an optic is, the smaller the minimum angle it can discern is.arrow_forwardHow many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!arrow_forward
- I would like you to compare the thickness of Saturn's rings to objects here on Earth if those rings were scaled down to the size of the objects here on Earth (hint: this means it is a ratio problem). Imagine the rings of Saturn like a DVD or CD here on Earth. The DVD has a diameter of approximately 12 cm, whereas the rings of Saturn have a diameter of approximately 280,000 km. The thickness of a DVD is about 0.6 mm and the thickness of the rings of Saturn at their thickest is approximately 1 km. If we were to scale the diameter of rings of Saturn down to the diameter of a DVD, how does the new thickness of the rings of Saturn compare to the thickness of the DVD? Please provide both the new thickness of Saturn's rings and how many times thicker or thinner they would be than a CD in your answer.arrow_forwardWhile looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.arrow_forwardWhich of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. For a telescope, increasing fe will decrease the actual size of the image seen by the person looking through the telescope. In crown glass, the index of refraction for red light is 1.512 and for orange light it is 1.514. Thus in crown glass, red light is faster than orange light. If unpolarized light is incident on a polarizer, 50% will pass through. The glasses for nearsighted people create real images for them to see. The smaller the diameter of an optic is, the larger the minimum angle it can discern is.arrow_forward

In 2007 Young and Buie measured Pluto as having a diameter of 2322 km. In 2015 the New Horizons probe reached pluto and measured it up close and we now know the actual diameter is 2372 km. What was the percent error of the 2007 measurement? Enter your answer as a percent with a negative value if the 2007 measurement was too small and a positive value if it was too large.arrow_forwardIf Titan could be moved out to the orbit of Neptune would its atmosphere freeze into solid nitrogen? The formula to estimate the blackbody radiation temperature in Kelvin is: where α is the albedo at 0.3, L the luminosity is 1.5 Watts/meter2, σ , the Stefan Boltzmann constant is 5.67 X10-8 W/m2/K.
