- 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…Hey what’s the answer to thisExplain why a massive, cool planet is more likely to have a thick atmosphere than is a less massive, hot planet.
- 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 FalseJupiter is slightly larger than Saturn but its density is about 2 times the density of Saturn. The reason for this density difference is a. Jupiter's higher mass and gravity compress its interior more b. Jupiter is more compressed by Sun's gravity c. Jupiter has larger volume d. Jupiter has larger proportions of rocks and metalQuestion 7 What type of mission collects information about multiple planets? Sample returns. Rovers. Flybys. Atmospheric probes. Question 8 Why are neutrinos so difficult to detect? There are very few of them, so collecting enough to study takes a long time. They are theoretical and may not exist. They move so fast they pass right through the telescope. They don't interact strongly with matter, so they will not cause a reaction on a CCD imager.
