The process of star and planet formation begins with a large cloud of gas and dust called a solar nebula. Rank the formation events that occur within a cloud from earliest to latest.

Rank from earliest to latest. To rank items as equivalent, overlap them.

The cloud is large, cool, and slowly rotating

The cloud collapses into a disk

Competing rotational and gravitational forces begin to flatten the cloud

The cloud becomes denser, heats up, and rotates faster

The cloud starts to contract under the influence of gravity

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
