Put the following stages of star formation into the proper sequence from earliest to latest:
Hint: When put into the proper order, each stage connects to the one before it and the one after it. Look for the key transition terms.
A. Infalling material forms a hot and luminous protostar at the center of the disk.
B. Newly-formed star settles onto the Main Sequence.
C. Massive, rotating, amorphous interstellar cloud collapses and fragments.
D. As the shrinking protostar heats up, hydrogen is ionized and a magnetic field forms.
E. Gravitational contraction causes protostar to shrink and heat as it descends the Hyashi track.
F. Magnetic bipolar outflows begin along rotation axis as the magnetic field forms.
G. Shrinking cloud collapses into a flat disk shape.
H. As bipolar outflows become stronger, powerful T-Tauri winds start clearing the nebula before the onset of nuclear fusion.
I. Onset of nuclear fusion in the core occurs around 15 million K.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
