Question

At an average opposition, the Earth and Mars are separated by 0.52 AU. Suppose an astronomer
observes Mars at opposition and that seeing blurs the images to a resolution of 1.0 seconds of arc.
What is the smallest surface feature the astronomer would be able to resolve on Mars? How does
this size compare with the diameter of Mars?

4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…

equattion : S/4 (1- a) = f*sigma*TS4 Solar Constant (W/m2) S = 1361 How sensitive is the temperature of the earth to changes in the atmospheric transmissivity (f)? The atmosphere is more transmissive (lets more radiation through) when CO2 and other greenhouse gases are lower. During the pre-industrial period, transmissivity (f) was probably around 62% (f = 0.62) and has been decreasing. Calculate how much the Earth's surface temperature would change if the transmissivity changes by ±0.01 (to 0.60 or to 0.62). ___ °C per 1% transmissivity change.
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…
