30: The Life Cycle of Stars Our Sun is an ordinary or "main sequence" star, 4. A survey of solid state physics; an introduction to crystal structures and the physics of electrons, lattice vibrations and photons; applications to semiconductors; magnetism; superconductivity; physics of nanostructures; brief introduction to selected current topics in condensed matter physics.
The focus is on electricity and magnetism. A qualitative study of stellar birth, stellar structure and evolution, stellar nucleosynthesis, the Hertzsprung-Russell Diagram, white dwarfs, neutron stars, supernovae, black holes, proto-planetary systems, origin of the solar system and the search for exoplanets; utilizes active learning methods that incorporate observations from the current generation of ground and space-based telescopes.
Electricity and magnetism are very closely related. When you point the thumb on your right hand in the direction of current flow, your fingers curl in the direction Magnetism and Astronomy (Challenge Science) the magnetic field.
Sometimes, electric current is created by the flow of other charged particles, like ions atoms that have a net electric charge due to a lack or surplus of electrons. Hubble also found a close relationship between a galaxy's distance and its "red shift," a change in light wavelengths caused by rapid movement away from us. The higher the value of the resistance, the more the material hinders or resists the current, and the more energy is lost as current flows through it.
Learn how the discovery of radioactivity and a mathematical demonstration by Einstein provided the compelling evidence. May be repeated Magnetism and Astronomy (Challenge Science) credit. To learn more about electrons and electricity, see the tab. Figures and show the time evolution of a vortex core moving from left to right and changing polarity when it hits an edge. This makes electromagnets very convenient because they can easily be turned on or off, and can create very strong magnetic fields.

Identify materials that are conductors and insulators. 28: Nuclear Fission and Fusion Reactions Prodigious amounts of energy can be released when atoms are split fission or when two nuclei, usually hydrogen, are forced together fusion. This creates an imbalance of positive and negative charges, called static electricity.
