Final answer:
The correct answer is 'a) Small Size' which is a common trait among the Planet Mercury, Rhode Island, and a dime. Mercury is the smallest terrestrial planet, with a fast revolution around the Sun and a high density due to its large iron-nickel core.
Step-by-step explanation:
The question seems to be asking for a common characteristic among: the Planet Mercury, Rhode Island, and a Dime. The correct answer, based upon the attributes provided, seems to be 'a) Small Size.' Mercury is the smallest terrestrial planet, Rhode Island is the smallest U.S. state, and a dime is the smallest coin in terms of thickness and diameter in the United States currency.
Mercury is particularly interesting due to its small size and large iron-nickel core, which contributes to its surprising density. With a diameter of 4878 kilometers and a mass of one-eighteenth that of Earth, it is less than half the size of Earth and yet has a high density of 5.4 g/cm³. Mercury has a very fast orbital speed, traveling around the Sun at 48 kilometers per second, completing its revolution every 88 days. Despite its small size, Mercury is difficult to see from Earth because it remains close to the Sun.
In terms of composition, Mercury has lost much of its silicate material, leading astronomers to believe that it has undergone one or more substantial impacts during its evolution. Mercury's composition includes a massive metallic core that makes up about 60% of its total mass. It is a planet largely made up of heavier elements like metals, with a sizable core that extends to within 700 kilometers of the surface.
Building a vacation home on Mercury would be extremely challenging due to the extreme temperatures, lack of atmosphere, and intense solar radiation that the planet is subjected to. Keeping such a house in repair would be nearly impossible under the harsh conditions of Mercury's environment.
