What half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
1/32 of the original amount.
How much is 5 years auto loan at 0.9 percent interest?
That would depend on the original principal (the amount you borrowed) and how they compute interest.
If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.
The half life of Radium-226 is 1600 years How many grams will remain from 5 grams after 365 years?
The amount of material left in radioactive decay is an exponential function. Therefore, the way you solve this is to write it as an exponential function; for example: f = e-kt, where "f" is the fraction remaining after a certain time, "t" is the time in any unit you choose (for example, years), and "k" is a constant you have to find out. Replace the numbers you know (for t = 1600 years, f = 1/2, since 1/2 of the original remains), and solve for "k". Then, write the equation again, this time with the constant "k" you figured out before, and the time (365 years). This will give you the fraction left after that amount of time.
If current birth and death rates remain constant the world's population will double in how many years?
40 years
The half-life of cobalt-60 is 5.3 years After years 1 4 of the original amount of cobalt-60 will remain?
After 1 year, 50% of the original amount of cobalt-60 will remain. This means that 50% will decay and 50% will be left. After 4 years, 6.25% of the original amount (50% of 50%) of cobalt-60 will remain.
The half life of cobalt 60 is 5.3 years After years 14 of the original amount of cobalt 60 will remain?
After 14 years, 1/16th of the original amount of cobalt-60 will remain, because 14 years is equivalent to 2.64 half-lives of cobalt-60 (14 years / 5.3 years/half-life). Each half-life reduces the amount of cobalt-60 by half, so after 2.64 half-lives, the original amount will be reduced to 1/2^2.64 which is approximately 1/16th.
Is there a warranty on 2006 Chevrolet colbalt catalytic converter?
8 years or 80,000 miles.
What is the amount of carbon 14 remaining after 28500 years?
Well, isn't that a happy little question! After 28,500 years, about 1/16th of the original amount of Carbon-14 remains. It's amazing to see how nature's clockwork can show us the passage of time in such a gentle and beautiful way.
What fraction of Carbon 14 will remain in charcoal burned in a primitive man's campfire approximately 28000 years?
Approximately 25% of Carbon 14 would remain in charcoal burned in a primitive man's campfire after about 28,000 years. This is because Carbon 14 has a half-life of around 5,730 years, so after multiple half-lives, only a fraction of the original amount will remain.
A Radio Decay Isotopes Has A Half Life Of 100 Years . A Sample Of 40 Grams Of The Isotopes Will Have A Mass Of Grams In 200 Years?
After 100 years, half of the original sample (20 grams) will remain. After another 100 years (total 200 years), only half of that amount (10 grams) will remain.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
After 15.8 years, half of the original sample of 60Co would have decayed. This means that 8 grams of the original 16 gram sample will remain unchanged after that time period.
What is 6 years at 30 percent?
After 6 years at a 30 percent interest rate, the total amount accumulated would be 1.30 times the original amount. This increase accounts for both the original value and the interest earned over the 6 years.
What half-life of C14 is 5730 years. What fraction of the original C14 would you expect to be present in a fossil that is 28650 years old?
1/32 of the original amount.
How many days will it take an amount of tritium to fall to a quarter?
Tritium has a half-life of around 12.3 years. To fall to a quarter of its original amount, it would take double the half-life, or around 24.6 years.
If the age of the Earth is 4.5 billion years and the half-life of 40K is 1.26 billion years what percent of the Earth's original amount of 40K remains today?
Approximately 25% of the Earth's original amount of 40K remains today, given that one half-life of 40K is 1.26 billion years. This means that half of the original amount decayed in 1.26 billion years, leaving behind the remaining 50%, which is now further decaying to reach 25% after 4.5 billion years.
How many grams remain after 20 years?
It depends on the substance and its rate of decay. The amount remaining can be calculated using the substance's half-life and the initial amount present.
