The rate at which a nebular cloud rotates increases as the cloud collapses to form systems of stars and planets. Consider a smallsegment 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 orbitaldistance rinitial = 2.5 x 104 km. After the cloud collapses, the same small segment is located at an orbital distancerinal = 3.2 x 10° km. Calculate the change of the rotational velocity, Ao, for the cloud segment, assuming perfectly circularorbits. Perform your work and report your solution using two significant figures.Δω-rad s-

How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!
Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.
The NASA Kepler mission detected a transiting planet that blocks 1.3% of the stars light and the host star has a radius 82% of the Sun's radius (the Sun has a radius of 700,000 km) what is the radius of the exosolar planet in km?
Exoplanets A and B are observed to orbit Star X in circular orbits at distances 1.1 AU and 10.2 AU from Star X, respectively ( 1 AU = 1.5 x 1011 m) . The orbital period of Exoplanet A is 244 days. What is the mass of Star X? (1 day = 86400 s.)
The Tully-Fischer method relies on being able to relate the mass of a galaxy to its rotation velocity. Stars in the outer-most regions of the Milky Way galaxy, located at a distance of 50 kpc from the galactic centre, are observed to orbit at a speed vrot determine the mass in the Milky Way that lies interior to 50 kpc. Express your answer in units of the Solar mass. 250 km s-1. Using Kepler's 3rd Law,
The Sun orbits around the center of the Milky Way on a circular orbit with a radius of 8 kpc, and at a speed of about 200 km/s.Suppose that the gravitational field of the Milky Way is dominated by a spherical dark matter halo. What is the mass of the halo within the radius of the solar orbit?
