The angular momentum problem in the nebular hypothesis refers to the discrepancy between the Sun's slow rotation and the rapid rotation expected from a collapsing nebula. Which of the following mechanisms is thought to have resolved this problem?
Question 2
During the accretion phase of planet formation, the growth of planetesimals is influenced by various factors. Which of the following best describes the role of gravitational instability in the formation of gas giants?
Question 3
The 'Grand Tack' model is a proposed scenario for the early migration of Jupiter and Saturn. What is a significant consequence of Jupiter's inward and then outward migration in this model?
Question 4
Chondrules are millimeter-sized spherical grains found in chondritic meteorites. Their presence provides crucial insights into the conditions of the early solar nebula. What is the generally accepted mechanism for their formation?
Question 5
The isotopic composition of certain elements in meteorites, particularly short-lived radioactive isotopes like Aluminum-26 ($^{26}\text{Al}$), provides strong evidence for which event in the early Solar System?
