The answer for this question would be Planetary Nebula.
Black holes are created when the star core has a mass of more than 2.5 times of the Sun. In Supernova, fo<span>r stars with mass of more than 8 times the mass of the Sun, death is signalled by a gigantic explosion: during the first second it can be as bright as a whole galaxy with hundreds of billions of stars. In Red Giants, it is </span>due to explosion of average stars like the Sun. Lastly, in Planetary Nebula, f<span>or small stars (that is less than 8 times the mass of the Sun), at the end of the Red Giant phase, the star can’t contract enough to generate the temperatures needed for further nuclear fusion.</span>
Its true hopefully this helps you.
Answer:
I don't really understood the question
Net force is determined by adding up all of the individual forces on an object. For example, to determine the net force on an airplane, you would add up the lift, weight, thrust, and drag<span>. If forces are in opposite directions, like lift and weight, then you subtract them. During takeoff, the net force on an airplane is forward and up. During landing it is backwards and down.</span>
