When a high-mass main sequence star runs out of both hydrogen and helium in its core, the core begins to fuse
When nuclear fusion ends in a high-mass star, the heavy elements formed in the star's core are released through a

The answer is carbon and supernova

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
