- How much would a 10lb bowling ball weigh on an exoplanet that was twice as massive as Earth but had the same radius? 1. 10lb 2. 40lb 3. 100lb 4. none of the aboveApproximately how many asteroids that are 0.89 km in radius would it take to make a planet which has a radius of 6590.0 km?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…
- Some astronomers argue that Jupiter and Saturn areunusual, while other astronomers argue that all solarsystems should contain one or two such giant planets.What is a mini-Neptune? Group of answer choices An exoplanet the size of Earth which appears to be habitable. An exoplanet with a radius between 1.4 and 2.8 times Earth radius. An exoplanet with a radius between 2.8 and 4 times Earth radius. An exoplanet with more water than Earth.What is a "hot Jupiter" Group of answer choices Exoplanets that are warmer than Jupiter. Exoplanet that are giant like Jupiter but orbits very close to their star. Any planet that is hotter than Venus. Jupiter size planets orbiting around stars much hotter than the Sun.
