I can do this by working from the definition of "half-life": in the given amount of time (in this case, hours.
I do not have the decay constant but, by using the half-life information, I can find it.
If possible, the ink should be tested, since a recent forgery would use recently-made ink.
As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.
It was developed right after World War II by Willard F.Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.Radiocarbon dating is a method of estimating the age of organic material. However, I note that there is no beginning or ending amount given.
How am I supposed to figure out what the decay constant is?
