Question 8 1 pts Which of the following statements is(are) true of radioactive carbon-14? 1. It...
Carbon 14 is a radioactive isotope produced in the upper atmosphere by cosmic rays. It has a half-life measured as 5730 : 40 years. Since plants and animals absorb carbon from the atmosphere, the percentage of carbon a living organism contains that is carbon 14 is equal to the percentage of carbon 14 in the atmosphere. When an organism dies, however (or when a layer of wood is laid down as bark in a tree), it ceases to absorb carbon....
7.3 The decay rate of the isotope carbon-14 (14C) is often used to establish the date on which carbon-containing matter died. In the upper atmosphere, cosmic radi- ation synthesizes 14C. This process balances the loss of 14C through radioactive decay. Living matter, which exchanges carbon with atmospheric carbon diox- ide and maintains its 14C level, produces 15.3 disintegrations per minute per gram of carbon it contains. Dead organisms no longer exchange carbon with the atmosphere, and the 14C content decreases...
Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...
1) Carbon-14 is formed as the decay product of Nitrogen-15, which was formed when a cosmic ray bombards the N-15. What is the particle equivalent of the cosmic ray involved in this decay process? 2) Carbon-14 get locked in organic material through this process. 3) How many half-lives of Carbon-14 decay will leave behind approximately 1/8 of the original mass of Carbon-14? 4) Using the equation for radioactive decay, if you start with one gram of radioactive substance that has...
1. Carbon-14 atoms produced in the upper atmosphere combine with oxygen to yield 14CO2, which slowly diffuses into the lower atmosphere, where it mixes with ordinary 12CO2 and is taken-up by plants during photosynthesis. When these plants are eaten, carbon-14 enters the food chain and is ultimately distributed evenly throughout all living organisms – so an equilibrium is established between the amount of C-14 consumed by the organism and the amount that is lost through exhalation of CO2 and excretion....
please explain too 1) There is 1.3 radioactive carbon-14 atoms for every trillion carbon atoms in living organisms. Carbon-14 beta decays to nitrogen-14 with a half-life of 5730 years. (a) What is the activity due to carbon-14 in a 5o kg person? (Assume that 18% of the mass is carbon.) (b) Calculate Q for the decay. (c) what is the annual radiation done that a pernon e.eives fion their own arn-ht thenua C 14.003242 u N 14.003074 u 1) There...
Using Python 3... Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...
Carbon-14 is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating. The half-life of carbon-14 is 5,730 years. If a fossilised tree trunk originally contained 8 nanograms of C-14, how long will it take for the C-14 to decay to 1 nanogram
True or False 6. Carbon-14 is a radioactive isotope of carbon. . 7. The 3 isotopes of hydrogen differ in the number of protons? 8. The kinetic energy does a 1000 Kg car have going 15 m/s is 15000 Joules. 9. A metal weighs 100 kg and has a volume of 4 m3 has a density400 kg/m. 10. Radiation is the process of transferring heat from one material to another by contact. 11 The normal hearing range is between 20...
1 pts Question 1 Which statement or statements are true about weather and climate? Mark all that apply. O Weather refers to short-term conditions in the atmosphere. Climate may change from day to day or season to season. Weather is the atmospheric conditions you expect, while the climate is what you actually get each day. O Climate represents an average of atmosphere conditions over a long period of time. 1 pts Question 2 In addition to carbon dioxide, which of...
