Chapter 10: Review Questions 3) Seven features of the active sun are: 1. Sunspots: these regions are darker and cooler than the rest of the suns photosphere; they are caused by magnetic fields that protrude at that area of the visible surface. 2. Plages: These are bright areas in the chromosphere. They are associated with magnetic fields emerging from the sun. 3. Solar Flares: these are ejections of large volumes of gas. They can sometimes head our way causing radio interference

the deuteron to the rest energy of the deuteron and the binding energy of the deuteron. Is it therefore reasonable to ignore electronic binding energies when doing nuclear calculations? 2. A neutron star (which is predicted to be formed in a supernova explosion) consists only of neutrons held together by the gravitational force. Using reasonable assumptions and stating what they are‚ calculate the mass of 10 cm 3 of neutron star material and compare this with the mass of the same volume of

My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously‚ nor do I believe that the earth is so delicately balanced. I don’t believe that the earth and its ecosystem are fragile. Many radical environmentalists do‚ they believe man can come along‚ all by themselves and change everything for worse. After hundreds of millions of years‚ they believe that we are the last two generations of human existence. And they think we can destroy

Pegasus is a famous constellation within Greek mythology about a winged horse. Pegasus has a story of a him coming out of Medusa and beheading her and that is how he came into this world as a magical horse in Greek mythology. Pegasus is a constellation that has a shape in it called the “Great Square.” Another constellation is tied in with Pegasus in a way that it is a horse but a much smaller version of Pegasus and its heads are touching as if they are in love. That constellation is named “Equuleus

formed‚ it cannot be fused to make more energy since it has such a high binding energy and is therefore very stable. The core will collapse under gravity and huge amounts of gas on the surface of the star will explode out. This star is now called a supernova. There are also neutron stars that form but that’s another process. These were some of the steps that take place when stars go through their life cycle. I hope you understand this topic more

The universe is made up of 93.5% of Hydrogen atoms‚ 6.3% of Helium and 0.2% of other elements. By looking at the spectrum of hot stars‚ upper solar atmosphere and solar wind‚ an abundance of Helium is determined. Only from the 1920s there were methods of calculating what elements were present in a gas by just observing its spectrum‚ due to the fact that different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after

From an outsider’s perspective‚ Grace Lynch seems like a quiet‚ small town‚ Taylor Swift lover who reads a lot. But in reality‚ Lynch is loud‚ and hates the evergrowing Taylor Swift fad. The high school senior‚ who is well rounded and confident‚ shows the world that the value in life is not the money or the fame‚ but rather the personal connections one makes.

expand at an accelerating rate; due to this conclusion‚ they think that dark energy’s existence is 99.996% real. Dark energy was not discovered a few days ago but in the 1990s when two groups of scientists proposed its. When the groups were observing supernovas‚ some of the stars were less bright than the expected from this event the scientists concluded that the universe’s expansion was accelerating. The claim that dark energy exists is support by the Integrated Sachs Wolfe effect. This effect states
