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.
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
How many milligrams of Co-60 remain after 104.7 min if you start with 10.0 mg of Co-60?
The half-life of Co-60 is 5.27 years. The time interval is 104.7 min = 0.0002 years approx which is 0.000038 half lives. So amount left = 9.9997 mg, approx.
The half life of cobalt 60 is 5.3 years After years 14 of the original amount of cobalt 60 will remain?
10.6 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 twice the half-life, 1/4 of the original amount remains. After 3 times the half-life, 1/8 of the original amount remains. Etc.
Is there a warranty on 2006 Chevrolet colbalt catalytic converter?
8 years or 80,000 miles.
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.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
The half-life of 27Co60 is about 5.27 years. 15.8 years is 3 half-lives, so 0.53 or 0.125 of the original sample of 16 g will remain, that being 2 g.
How many days will it take an amount of tritium to fall to a quarter?
The half life of Tritium is 12.32 years. it would therefore take 24.64 years for the amount to fall to a quarter of the original.
How much cesium with a half life 2 years would remain from a sample after 4 years?
The equation for half-life is ... AT = A0 2 (-T/H) ... where A0 is the starting activity, AT is the activity at some time T, and H is the half-life, in units of T. 55134Cs has a half-life of 2.0652 years. Plugging in the known values, we get ... AT = 5.8 2 (-11.5/2.0652) AT = 5.8 2 -5.5685 AT = 0.12222
Does baby hair differ from adult hair?
Of Course It Does as it is the hair one was born with - once this is shed the actual texture is reveal - the remnants of the original texture remain on some adults for years ( hairline, nape ) if they allow it to remain untouched
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?
8.4
Why cant carbon-14 be used to date material that is older than 75000 years?
Carbon has a half life of 5730 years. That means that after 5730 years there'll only be half the amount left. After about 11500 there will be a quarter of the original. After 75000 years there will be about 0.0001 of the original sample which is too small to date accurately?
If 1.0 mg of cesium-137 decays over a period of 90 years how many mg of cesium-137 would remain?
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.
Can you pay a fine to get a judgment removed from your credit report?
No, judgments remain on a credit report for seven years. Some types of judgments are renewable and therefore can remain on a report an indefinite amount of time. If you are willing to pay a fine, why not just pay the judgment?
