Which of the following types of stars is most likely to end up as a supernova?

The graph A is the right answer.

Explanation:

A supernova happens when there is a change in the nucleus, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.

As the star runs out of nuclear fuel, some of its mass flows into its nucleus. At that moment the wavelength emia by the star exceeds 700 nm / s. Eventually, the core is so heavy that it can not withstand its own gravitational pull. The nucleus collapses, resulting in the giant explosion of a supernova.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
