Question
Which of the following statements is correct for dwarf planets?The recommended time to answer this question is 2.5 minutes.Soru 19YanıtTheir centers are hot enough to initiate nuclear reactions that can burn hydrogen.They cleared their orbits from objects similar to them.Celestial bodies such as Ceres and Pluto are considered to be in this classification.They are objects between planets and stars.Their diameters range from about 2 meters to hundreds of kilometers.
Solution
The correct statement for dwarf planets is "Celestial bodies such as Ceres and Pluto are considered to be in this classification."
Here's why:
-
"Their centers are hot enough to initiate nuclear reactions that can burn hydrogen." - This is incorrect. This statement is true for stars, not dwarf planets. Dwarf planets do not have the necessary mass to create the pressure and temperature needed for nuclear fusion.
-
"They cleared their orbits from objects similar to them." - This is also incorrect. One of the criteria that separates planets from dwarf planets is that planets have cleared their orbits of other debris, while dwarf planets have not.
-
"Celestial bodies such as Ceres and Pluto are considered to be in this classification." - This is correct. Both Ceres and Pluto are classified as dwarf planets by the International Astronomical Union.
-
"They are objects between planets and stars." - This is incorrect. Dwarf planets are not between planets and stars in terms of size or other characteristics. They are a separate category of celestial bodies.
-
"Their diameters range from about 2 meters to hundreds of kilometers." - This is incorrect. Dwarf planets are much larger than 2 meters in diameter. The smallest known dwarf planet, Ceres, has a diameter of about 940 kilometers.

4.Question 4The terrestrial planets appear to have taken much longer to finally assemble than the gas giants did. Which of the following statements about these timescale is NOT true?1 pointOne reason that the gas giant formation timescale is thought to be so fast is that we do not observe stars to have gas around them after they are ~3 Myr oldWe can learn about the timescale of terrestrial planet differentiation by looking at isotopic ratios of hafnium and tungsten.Oligarchs form very quickly through runaway growth but because they are gravitationally isolated it takes a long time for them to assemble into larger bodies.Mars differentiated quickly, so tungsten-182, the radioactive decay product of hafnium, is abundant in Martian meteorites.All of these statements are trueGrowth of the terrestrial planets was slowed by the rapid growth of the gas giants, which caused oligarchs to have have velocities and break apart
