Essay on geothermal power in kannada |
|
Answer» Geothermal energy is the thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials (in currently uncertain but possibly roughly equal proportions). The adjective geothermal originates from the Greek roots γῆ (gê), meaning Earth, and θερμός (thermós), meaning hot.The Earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, but only a very small fraction may be profitably exploited. Drilling and exploration for deep resources is very expensive. Forecasts for the future of geothermal power depend on assumptions about technology, energy prices, subsidies, plate boundary movement and interest RATES. Pilot PROGRAMS like EWEB's customer opt in Green Power Program show that customers would be willing to pay a little more for a renewable energy source like geothermal. But as a result of government ASSISTED research and industry experience, the cost of generating geothermal power has decreased by 25% over the 1980s and 1990s. In 2001, geothermal energy costs between TWO and ten US cents per kWh. About 100 thousand people are employed in the industry. |

Which one is strongest acid Bf3 or bcl3 |
|
Answer» b3fExplanation:In contrast, toward weak bases such as CO, BF3 is a STRONGER Lewis acid than BCl3. ... It takes more energy to lengthen the short STRONG BF bonds than the longer WEAKER BCl bonds and it is for this reason that BCl3 is a stronger Lewis acid than BF3 toward a strong base such as NH3. |

Define atom and it's sub atomic particles. Define plum pudding model of atom.What was the drawback of plum pudding model.Explain Rutherfords experiment.Explain the model of atom. proposed by Rutherford |
|
Answer» atom and it's sub atomic particles.A subatomic particle is a unit of matter or energy that's the FUNDAMENTAL makeup of all matter. According to modern atomic theory, an atom has a nucleus, which is its center, or core. The nucleus contains subatomic particles: protons and neutrons. Protons are positively-charged particles.plum pudding model of atom.The plum pudding model is one of several historical scientific MODELS of the atom. ... The plum pudding model has electrons surrounded by a volume of positive charge, like negatively-charged "plums" embedded in a positively-charged "puddingthe drawback of plum pudding model.Thomson's atomic model failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain an atom's stability. The theory did not mention anything about the nucleus of an atom. It was unable to explain the scattering experiment of Rutherford.Rutherfords experiment.Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the UNSEEN WORLD of atomic structure.the model of atom. proposed by RutherfordThe Rutherford model shows that an atom is MOSTLY empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. Prior to Rutherford, the popular model of the atom was the plum pudding model, popularized by J.J. |

The relationship between energy of photon of light and it's frequency is given by |
|
Answer» energy is the energy carried by a SINGLE photon. The amount of ENERGYIS DIRECTLY proportional to the photon'selectromagnetic frequency and thus, equivalently, is inversely proportionalto the wavelength. The HIGHER THEPHOTON's frequency, the higher itsenergy. |

A polar covalent bond is formed between the two atoms because the difference in their electro negativity is :OC - O between 0.5-20O C-H greater than 1.0O C-H less than 0.5O.C-greater than 2.0 |
|
Answer» Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the ONE with the PARTIAL NEGATIVE charge. The greater the DIFFERENCE in electronegativity, the more polarized the electron distribution and the larger the partial CHARGES of the atoms.Explanation:Thank you❤️❤️ |
