How do we determine the age of an oil deposit
a. By calculating the amount of lead that has decayed from uranium
B. By measuring its ratio of carbon-14 to carbon-12
C. By measuring the amount of uranium that has not decayed into lead
D. By exposing the sample to cosmic rays in the environment to produce carbon-14
E. By calculating the amount of carbon that has decayed into nitrogen
Homework Answers

Scientists can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, C , with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates through food chains. When a plant or animal dies it stops replacing its carbon and the amount of "C begins to decrease through radioactive decay. Therefore, the level of...

My Notes Ast our Teacher Scientist can determine the age of andient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 1C, with a haf-ife of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates through food chains. When a plant or animal dies, t stops replacing its carbon and the amount of1C begins to decrease through radioactive decay. Therefore,...

We
want to determine the strength of the relationship between the
independent variable "age" and the dependent variable "intelligence
quotient". In our sample, the mean of the variable "age" is equal
to 14, and its variance is equal to 46,4. The mean of the variable
"intelligence quotient" is equal to 102, and its variance is equal
to 0. The list of corresponding data for the two variables is
pictured below.

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....

An ancient club is found that contains 180 g of pure carbon and has an activity of 5.5 decays per second. Determine its age assuming that in living trees the ratio of (14C12C)(14C12C) atoms is about 1.40×10−121.40×10−12. Note that the half life of carbon-14 is 5700 years and the Avogadro number is 6.02×10236.02×1023.

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...
