According to the table, compared to the silver garden spider’s flag silk, the domestic silkworm’s silk has:
Relative to the center of the protostar, does gravity more likely accelerate gas particles inward or outward, and does RP more likely accelerate gas particles inward or outward?
Based on Scientist 2’s argument, do gas particles more likely accrete near the equator or near the poles of a protostar with a disk?
One of the most massive stars known is Eta Carinae, which has an approximate mass of 120 M S . Based on the arguments of Scientists 1, 2, and 3, respectively, what is the minimum number of stars, each formed entirely by accretion, that would have been required to form Eta Carinae?
When the effect of RP overcomes that of gravity, a star is said to have “emerged from its envelope,” because that is the first time the star is directly observable from outside the cloud. An observation of which of the following stars emerging from its envelope would support Scientist 2’s argument but weaken Scientist 1’s argument?
Scientists 2 and 3 agree that a disk forms around a protostar as a result of the protostar’s:
Which of the scientists, if any, would be likely to agree that the Sun could have formed entirely by accretion?
