It is not enough to just answer the question, so here is a breakdown of how the energy is transferred from the core to the Earth and the other objects in our solar system. The Sun’s extends from the center to about 0.25 of the solar radius. It has a density of 150 g/cm3 and a temperature of close to 13,600,000 K. Energy is produced by nuclear fusion during a series of steps called the proton-proton(P-P) chain, converting hydrogen to helium. The core is the only part of the Sun that produces an appreciable amount of heat through fusion(99%). The rest of the star is heated by energy that is transferred outward from the core and the layers just outside.
Continuous spectrum: a spectrum that exhibits all the wavelengths of visible light 13. Line Spectrum: a spectrum showing only certain discrete wavelengths 14. Quantum model: The quantum mechanical model is based on quantum theory, which says matter also has properties associated with waves. According to quantum theory, it’s impossible to know the exact position and momentum of an electron at the same time 15. Ground state: the lowest possible energy state of an atom of molecule 16.
Use the example as a guide, using complete sentences for all subpoints. 1. Our place in the universe a. The modern view of the universe 1) What is our Sun and what is its role in the solar system? Our Sun is a star, just like in our night sky.
It is, therefore, true to say that everything that exists in the Universe is not permanent. The importance of the Sun to life on Earth 1. Earth and other planets are linked to the Sun by a gravitational force. The gravitational force of the Sun is always present to keep Earth in the right position to receive light and heat from the Sun. 2.
Neutron Star: A very compact, dense stellar remnant composed almost entirely of neutrons. Universal Time: Greenwich Mean Time: the local time at the 0 meridian passing through Greenwich, England; it is the same everywhere. Pulsar: A pulsating source associated with a rapidly rotating neutron star with an off-axis magnetic field. Radio Telescope: A telescope designed to detect radio waves. Radio Waves: Long-wavelength electromagnetic radiation.
Jamarquis Green Written Assignment General Biology 4/13/14 1. Light is a form of energy known as electromagnetic energy it travels through rhythmic waves, the distance between the crests that become formed are called wavelengths these wavelengths range from less than a nanometer which is equivalent to a gamma ray which humans can’t visibly see too more than a kilometer which equivalent to radio waves the entire range of radiation is known as the electromagnetic spectrum which measures light. In plants light energy is used to convert solar energy into chemical energy what this means is that the heat from the light causes the plant to undergo different changes due to the heat that it has absorbed. Also light energy contains ample amounts
When the electron returns to a lower level, a photon with that energy difference is emitted. The peaks in the emission spectra are very sharp and known as line spectra. This emission spectra can be used in identification of elements because the spectra is different for each element. Materials: 1. Spectrum tubes (known and unknown) 2.
Question 1: How does solar energy compare with fossil fuel energy in satisfying basic energy needs? What are the three fundamental problems in harnessing solar energy? Solar energy basically does the same as fossil fuel in providing for and satisfying basic energy needs. Example, flat plate collectors are used in warm climates to collect the suns heat and store it to be used to warm up water, solar energy can also be used and converted to provide electricity. Solar energy is more cost efficient and cleaner than the use of fossil fuels.
A microwave works with the use of radio waves. (Kayne, 2012) The radio waves pass through the item that is being heated but not the container or walls of the microwave. When the radio waves enter the items the atoms in the item move around and produce heat. This allows the object to be heated up very fast with intense
What is electromagnetic radiation? Cell phones communicate with nearby cell towers through electromagnetic radiation waves, a form of energy located on the electromagnetic spectrum between FM radio waves and microwaves. Electromagnetic radiation (EMR) is a form of energy similar to that used to cook food in a microwave. EMR uses waves to travel through the atmosphere. EMR has electric and magnetic fields that surround devices such as cell phones, laptops, and various other electronic equipment (www.cancer.org).
