Carbon 14 is what a living thing gives off. It helps archaeologists tell how long ago something died (the less carbon 14, the longer ago it died).
<><><>
Carbon-14 is a specific isotope of the element carbon. It "decays" to another isotope of carbon. Decay begins when the living thing (like a tree) dies. By measuring the percentage of C-14 to regular carbon, they can determine ABOUT how long the item has been dead. Not a precise measurement, it is in hundreds or thousands of years.
A test that archeologists use to find out how old a person is. Also called Dating
------------------------------------------------------------------------------------------------------------------------------------
You can not use it to test how old a LIVING person is. Archeologists use the method of Carbon 14 dating to determine the age of any biological relic containing some carbon.
Carbon 14 is an isotope of carbon made in Earths upper atmosphere and it has a half life of 5730 years, enabling dating back to about 45,000 years before the present.

What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock
What is the difference between object oriented testing and conventional testing?
Conventional testing is the traditional approach to testing mostly done when water fall life cycle is used for development, while object oriented testing is used when object oriented analysis and design is used for developing enterprise software. Conventional testing focuses more on decomposition and functional approaches as opposed to object oriented testing, which uses composition. The three levels of testing (system, integration, unit) used in conventional testing is not clearly defined when it comes to object oriented testing. The main reason for this is that OO development uses incremental approach, while traditional development follows a sequential approach. In terms of unit testing, object oriented testing looks at much smaller units compared to conventional testing
Why testing is important in science?
Testing is an very important in science because of following reasons- 1. Without testing science is just an theory,2. Testing gives you results may be positive or negative,3. Testing is an easiest way to prove theories, concepts, formulas, etc,.4. With help of testing you can formulate the theory.5. Many more reasons.....
What process is involved in in all methods of testing hypotheses?
Data Collection is involved in all methods of testing hypotheses.
Does science develop without testing a hypothesis?
No, science does not advance without testing hypotheses.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
What is the mass number of carbon14?
Carbon is a non metallic element. Mass number of it is 12.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
Why are atomic masses written as averages?
elements exist in more than one form eg carbon 12 and carbon14

What is the preferred order for performing testing on information technology project?
1. unit testing,integration testing, system testing, user acceptance testing. 2. unit testing, system testing , integration testing,user acceptance testing. 3. unit testing, system testing , user acceptance testing,integration testing. 4. unit testing, ,integration testing, user acceptance testing,system testing.
What comes after unit testing?
These are the next testing levels after unit testing: 1 Integration testing 2 Component interface testing 3 System testing 4 Operational Acceptance testing
What is non functional testing in software testing?
It is testing of "how" the system works. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing. Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
Difference between functionality testing and load testing?
Functionality testing is what is expected. Load testing is what it actually did.
What are different types of testing?
There are 2 types of Testing 1.Manual testing 2.Automated testing
