Width 100 km, orbit 80 000 km from Saturn. Width 1 km, orbit 120 000 km from Saturn. Width 2 km, orbit 63 000 km from Neptune. no chat GPT HAND WRITTEN ONLY OTHERWISE WILL LEAVE A DOWNVOTE4) 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…Let's assume it took Voyager 1 13 years to reach the edge of solar system at a distance of 40 AU. How fast was voyager 1 traveling in Km/hr?
- If a protostellar disk is 210 AU in radius and the disk plus the forming star together contain 4 solar masses, what is the orbital speed at the outer edge of the disk in kilometers per second? (Hint: Use the circular orbital velocity formula )At rest carbon emits a spectral line at 364.0 nm. If this line is observed at 410.0 nm from exoplanet host Helvetio's, how fast is Helvitios moving toward or away from us in km/s?the nearest star to our sun is alpha centauri, which is about 4.4 light-years away. assume that it too has an Oort cloud about 1.6 light years in diameter. Show that there is enough space between us andnit to fit 1.75 solar systems.
- If there was a planet orbiting a first generation star, which planet in our solar system would it resemble most? Would it be likely for such a planet to have life?2. The destructive "Tunguska Event" of 1908 seems to have been due to an airburst by a modest-sized asteroid a direct impact on land by a large asteroid an ocean impact by a comet a nearby supernova explosion Astronomers have determined that the probability of a significant asteroid impact on Earth during your lifetime is about the same as the probabilty that you'll win the lottery. True FalseHow does the protostellar disk play a role in these key areas of our own solar system: same general direction of rotations and revolutions, orbital inclinations are within a few degrees of each other instead of randomly distributed, and planet compositions?
