Trees can absorb the carbon dioxide emitted in generating electric power. Part A Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses 1.1 x10% J of energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power plant that generates the electricity is 31 % efficient at converting the carbon in coal to electrical energy and that typical coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned. Express your answer using two significant figures. Hν ΑΣφ n = trees/year Submit Request Answer
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
