The half-life of fluorine-20 is 114 seconds After 14 seconds how much of the original amount of fluorine-20 will remain?
THE QUESTION IS INVALID. THE HALF-LIFE OF FLUORINE-20 is 11.07 SECONDS. There will be about 0.92 of of an isotope with a half-life of 114 seconds remaining after 14 seconds. The equation for half-life decay is AT = A0 2(-T/H) where T is time and H is half-life. 2(-14/114) is equal to about 0.92. In the case of fluorine-20, 2(-14/11.07) is about 0.42.
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
To determine the age of the artifact, you can use the formula for exponential decay of radioactive elements: (N = N_0 \times (1/2)^{t/T}), where N is the final amount (3.1% of the original), N0 is the initial amount (100%), t is the time passed, and T is the half-life (5730 years). By substituting the values, you can solve for t, which will give you the age of the artifact.
Can you use carbon dating to find out how old something is around 40 years old or newer?
Carbon dating measures the amount of carbon halflives that an object's carbon-14 has seen. A halflife is the amount of time it takes for half of the C-14 present to decay into a different element (N-14). A carbon halflife is 5730 years so you wouldn't be able to tell with such a small amount of time.
What is the half life of uranium 238 if 85.719 percent of any given amount remains after 1 billion years?
The halflife of 235U is 704 million years. 1420 million years is approximately two halflives, so about 24.7% would be remaining.
After how many days 1-4 of the original amount of gold 198 will remain?
After 4 days, only 1/16 of the original amount of gold (198/16 = 12.375) will remain.
The half life of fluorine-20 is 11.4 seconds After seconds 1'4 of the original amount of fluorine-20 will remain?
22.8 seconds
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
