- What are the conditions necessary for a terrestrial planet to have a strong magnetic field? A molten metallic core only Fast rotation only A rocky mantel only Both a molten metallic core and fairly fast rotation Both a molten metallic core and a rocky mantle4) 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…What is necessary for differentiation to occur in a planet? (A) It must be a mixture of materials with different densities (B) The materials inside the planet must be able to flow (C) The planet must have metal and rock in it O (B) Just A & B A, B and C (A)
- If you visited a planet in another solar system and discovered that it was heavily cratered, but its small moon was nearly crater free, why would that be a surprise? Speculate about what might have happened to those objects.The Solar Nebula model introduces the concept of ‘frost line’. Where are asteroids and comets found with respect to this frost line? How is their location connected to their composition?Phobos, one of Mars’ moons, is very slowly spiraling down towards the planet. Do you think that Mars will one day have rings? Explain your reasoning,
