Say we discover two new planets — Sram and Noom. They are both… Say we discover two new planets — Sram and Noom. They are both believed to have a core of rock surrounded by a mantle of ice. These two planets have the same diameter, but Sram has a mean density of 2800 kg/m3 and Noom has a density of 1400 kg/m3.a.) Which has the thinner mantle of ice, Sram or Noom? Explain why. b.) Yrucrem has the same mean density (2800 km/m3) as Sram but Yrucrem has a radius half that of Sram. Which planet will have cooled faster?c.) What would be the most astronomically obvious evidence that you would look for on the surfaces of Sram and Yrucrem to confirm your hypothesis of which planet had cooled first?  Science Astronomy PHYSICS 102 Share (0)
