Without it, millions of citizens would not be as well informed.
The benefit of being informed is that listeners are able to more intelligently discuss issues with, and have a greater influence on, family, friends, co-workers, and even strangers. However, as valuable as talk radio is, more often than not it falls short of its potential. Pass a law repealing the Johnson Amendment that prohibits churches and religious groups from being involved with politics.
Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
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.
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
How do scientists know how old an object or human remains are?
Not only is that restriction unconstitutional, but people of faith supported Trump big time, and Trump promised to repeal it, so just do it.
Put a clause in the upcoming infrastructure bill that says only states that have right-to-work laws AND no sanctuary cities will get money.
