Question

determine which physical conditions are necessary to support nuclear fusion and formation of stars. lower temperature higher temperature increased gravitational attraction decreased gravitational attraction promotes stellar formation does not promote stellar formation

Explanation:

Nuclear fusion in stars needs high - temperature to overcome the electrostatic repulsion between atomic nuclei and high gravitational attraction to compress the stellar material. Lower temperature and decreased gravitational attraction do not meet these requirements.

Answer:

Promotes Stellar Formation: higher temperature, increased gravitational attraction
Does Not Promote Stellar Formation: lower temperature, decreased gravitational attraction
