[view & print course content summary] ACC 198 Seminar and Project: Accounting Capstone 4 cr. [view & print course content summary] ACC 211 Principles of Accounting I 3 cr.Prepares students to complete the Certified Bookkeeper examination given by the American Institute of Public Bookkeepers (AIPB) using a review course prepared by the AIPB. Provides students an opportunity to integrate skills learned in prior accounting courses and apply those skills to the real-world practice of accounting through a business simulation project. Introduces accounting principles with respect to financial reporting.But this time, the mass it started with is half of the initial mass, so that means that you're going to be left with one quarter of the initial mass after 2 half-lives pass.
Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.
Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).
The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.
The carbon-14 decays with its half-life of 5,700 years, while the amount of carbon-12 remains constant in the sample.
By looking at the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely. So, if you had a fossil that had 10 percent carbon-14 compared to a living sample, then that fossil would be: t = [ ln (0.10) / (-0.693) ] x 5,700 years t = [ (-2.303) / (-0.693) ] x 5,700 years t = [ 3.323 ] x 5,700 years Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old.
Over the past eight years we have had hundreds of students join us from all over the world.
