Can carbon dating be used on bones a million years old?
No, there are no detectable levels of carbon-14 left in any sample older than roughly 40,000 years. Without carbon-14 in the sample, no date can be determined.
Is carbon dating wrong?
Carbon dating is only accurate up to about 60 000 years. It makes the assumption that the concentration of C-14 in our atmosphere has been relatively constant for the last 60 000 years. If this assumption is correct then carbon dating is accurate. It cannot be used for samples less than around 100 years due to the testing of atomic bombs which altered the 14C levels. Calibration curves are used to date the age of know antiquities (they are mentioned in historical documents so their age can be known). Other than that there are inaccuracies of a few percent as the object gets older than several thousand years.
How many levels are on the Certificate of Merit for piano?
It has ten levels plus ARCT Actually there are different types of levels depending on what you take an exam for. The California exam has 10 levels. The National exam has 16 levels. The "Royals" have 8 levels. There are also more.
Did good feeling or levels come first?
Levels came out before good feeling. Flo rosa sampled the song levels, making levels the first to be released
How carbon-14 dating can provide the age of a dead animal or plant?
All things lose a small amount of carbon-14 over time (decaying to nitrogen-14) and scientists measure the amount of carbon-14 remaining and see how much has been lost compared to a new animal. Certain adjustments have to be made to this initial estimate as the amount of carbon-14 in the environment varies over time. Natural carbon-14 is made in the upper atmosphere by the result of the reaction of cosmic rays with atmospheric nitrogen. The levels of cosmic rays vary with the position of our solar system in the galaxy and events in nearby stars and in the universe beyond our galaxy. Also carbon-14 levels are elevated significantly above these natural levels by the neutrons emitted in above ground nuclear tests, significantly skewing carbon-14 dates of samples from 1945 until the present time (although most above ground nuclear testing stopped in 1963 this excess carbon-14 remains in the environment and is therefor still being incorporated into living things today).
In radiocarbon dating the carbon-14 levels in the object being dated are compared with .?
In radiocarbon dating, the carbon-14 levels in the object being dated are compared with _____.
What factor reduces the accuracy radiocarbon dating?
Atmospheric carbon-14 levels change over time
What is ratioactive dating called?
Radiocarbon Dating. It measures the levels of carbon 12, a radioactive substance in everything, and based on how much is left scientists can determine how old something is.
What happens to the levels of carbon dioxide and water during aerobic exercise compared to their levels when the performer is at rest?
eutrophication
How is convection energy compared to the transfer of energy in the upper levels of the troposphere?
This is lame
A correlation between physical attractiveness and dating frequency of plus 0.60 would indicate that?
Less frequently dating is associated with lower levels of physical attractiveness.
How many levels does mw2 have compared to call of duty 4?
Mw2 has 5 more levels than the first call of duty. There are 70 levels in mw2 but on the first modern warfare there is only 65.
Is carbon-14 dangerous to humans or to the environment?
No. The carbon isotope Carbon-14, or radiocarbon, is found in the human body in the same proportions as there is carbon in the atmosphere. It comes to us from the food we eat, but the levels are too low to be dangerous, either to us or to the environment.
What are some dating sites for Asian people?
Eharmony is a very reputable dating website. They can match you with whom you are most compatible with on many different levels. If you are looking for a strictly asian dating site I would suggest looking into asiansinglesconnection.com
Where can I find some more information on single dating?
There are tons of dating sites. You can visit eharmony.com or match.com. These sites will match you with people who share your likes and interests on many different levels.
Niels Bohr predicted that the electrons would be found orbiting the nucleus in energy levels that could be compared to what?
Niels Bohr predicted that the electrons would be found orbiting the nucleus in specific energy levels that could be compared to the rungs of a ladder. He proposed that electrons can only exist in these discrete energy levels and that they move between levels by absorbing or emitting specific amounts of energy. This led to the development of the Bohr model of the atom.
When to use completion tests?
To measure lower levels of cognitive ability and to minimize guessing compared to multiple choice.
