What is a supernova? What do supernovas produce?

Answer 1

A supernova is a big explosion when a star explodes.

A supernova is an explosion that blasts away heavy elements (silicon, oxygen, nitrogen, iron, lithium, and so on) that the star produced over hundreds of light years. Stars with masses greater than our Sun continue to fuse heavy elements until the time comes to fuse iron, which is so heavy that the star cannot fuse it. In other words, the star is collapsing and all of its mass is being pumped into the core, which eventually collapses and turns into a black hole, white dwarf, or neutron star, depending on the star's mass.

A supernova is a massive explosion of a star that releases a great deal of energy. Supernovas create elements through the process of nucleosynthesis, and the remnants of their explosions can form black holes or neutron stars.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
