The rate at which a nebular cloud rotates increases as the cloud collapses to form systems of stars and planets. Consider a small segment of a nebular cloud with a mass m of 1.9 x 1027 kg, tangential velocity vinitial equal to 6.8 km s¯1 located at an orbital distance rinitial = 2.5 × 10ʻ km. After the cloud collapses, the same small segment is located at an orbital distance r'inal = 3.2 × 10° km. Calculate the change of the rotational velocity, Aw, for the cloud segment, assuming perfectly circular orbits. Perform your work and report your solution using two significant figures. 5.0 x10¬6 Δω- rad s-1 Incorrect
