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?
10 grams... If the half-life is 100 years, that means after 100 years, half the original mass remains. After another 100 years, the mass is halved again. 40/2=20... 20/2=10.
How much of a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
When you move a file a copy of the file remains in the original location?
When you move a file, the file is physically transferred to a new location. There is no copy left in the original location, only the file in its new destination. If you want to keep a copy in the original location, you need to use the "copy and paste" function instead of the "cut and paste" function.
Why After three half-lives what fraction of a radioactive sample remains?
After three half-lives, only 1/8 (or 12.5%) of the original radioactive sample remains. This is because each half-life reduces the amount of radioactive material by half, so after three half-lives, you would have (1/2) * (1/2) * (1/2) = 1/8 of the original sample remaining.
How much of a radioactive substance remains after 10 hours if its half life is 5 hours?
After 10 hours, 25% of the radioactive substance remains because each half-life reduces the amount by half. So, after the first 5 hours, 50% remains, and after the next 5 hours, half of that amount remains, which is 25%.
Is it false that dinosaur footprints are original remains?
Yes, it is false that dinosaur footprints are original remains.
How many Percent does the original remains of the Philippine Forest have?
20 percent of the original remains of the Philippine forest
Why the density of enriched uranium remains constant?
Absolutely correctly speaking the density of different isotopes are not identical; but the differences are very small, especially for heavy isotopes.
How are the original remains of shells bones and teeth of animals and fish formed into fossils?
Mineralization occurs in the original remains, inside the shells bones and teeth, of animals and fish. This process turns remains into fossils.
How do the number of neutrons and protons change for isotopes of the same element?
Proton count remains the same, but neutron count can vary
What are the original remains of small insects preserved in?
amber
Which correctly lists the three elements that geologists measure to determine the age of an organism’s remains?
Geologists measure the amount of carbon-14 present, the ratio of parent isotopes to daughter isotopes in radioactive decay, and the layers of rock surrounding the fossil to determine the age of an organism's remains.
After one half-life what percent of the original uranium remains?
By definition, 50%. Half life is the time for half of the original sample to decay.
In what year were the remains of the original Globe Theatre found?
The remains of the Globe Theatre in London were discovered in 1989.
After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
Compare and contrast original remains with other kinds of fossils what kinds of information would only be available for the origninal remains. are there any limitations to the use of origanial remain?
Original remains are the actual body parts of an organism, such as bones or teeth, while other fossils are impressions or molds of the organism. Original remains can provide information about soft tissues, behavior, and physiology that other fossils cannot. However, original remains are rare and may be subject to decay or damage, limiting their availability for study. Additionally, original remains may not always be well-preserved or complete, which can limit the amount of information that can be obtained from them.
Why is original remains is important to us?
Because oetzi is awesome
