Determine which physical conditions are necessary to support nuclear fusion and formation of stars.

The physical conditions that are necessary to support nuclear fusion and formation of stars are;

On the lower temperature and  increased gravitational attraction, it is more likely for stars to be formed and nuclear fusion occurs.

Stars form in cold, dense quarters of space called molecular clouds. When the force of gravity stretching in on the cloud is greater than the intensity of internal pressure pushing out, the cloud collapses into a protostar.

because the asteroid belt is between the mars and jupiter orbits, it is around 2.2 to 3.2 astronomical units (au) from the sun – which is approximately 329,115,316 to 478,713,186 km. the average distance between objects is a massive 600,000 miles.

explanation:

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
