Energy Star (trademarked ENERGY STAR) is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) that promotes energy efficiency. What is described symbolically : When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant o red super giant. 2 times c. 1×1016 times d. 625 times e. 6.3×1014 times a constellation visible to everyone on Earth. Gram-Rad A star's life is … This causes the hydrogen atoms to rip apart to form helium (nuclear fusion of hydrogen atoms). A star's energy comes from combining light elements into heavier elements in a process known as fusion, or "nuclear burning". Stars. In star formation, the kinetic energy to do this comes from the conversion of gravitational energy into thermal energy by the Kelvin Helmholtz contraction. The simple answer is that the Sun, like all stars, is able to create energy because it is essentially a massive fusion reaction. When an object is held in a vertical position, it has gravitational potential energy. Like you, I would have chosen answer A, including both the planet's kinetic and gravitational potential energy in the planet's "total mechanical energy". 14. This may be the fate of our Sun, too. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Just as a low-mass main sequence star runs out of fuel in its core, it actually becomes brighter. Because iron isn’t really the final element produced in a collapsing star. For example, students may respond that knowing where our energy comes from may be key to understanding how long it will last, as in the case of non -renewable energy.
