Science what is a sample taken without bias?
The answer is Random Sample
Frank has a sample of steel that weighs 80 grams. If the density of his sample of steel is 8 gcm3 what is the sample and volume?
Its is 10 cm³ hun
The collection of all possible outcomes of an experiment is called?
sample space
What two things must be true for a sample to be useful?
they must be correct and they must be the right kind of sample
How Many Halflife Are These In A 100-year Span How Many Grams Of The Sample Would Remain At The End Of The 100 Years?
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
How do you identify beta decay?
A sample of 187 rhenium decays to 187-omium with halflife of 41.6 billion years. If all 188 osmium are normalized isotopes.
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
How much of a 100 gram sample would remain unchanged after two hours?
This would depend on the specific sample and its stability. Without additional information, it is not possible to determine how much of the sample would remain unchanged after two hours.
A sample of radioactive isotope has a halflife of 1 day how much of the original sample will be left at the end of the fourth day?
If a sample of radioactive material has a half-life of one week the original sample will have 50 percent of the original left at the end of the second week. The third week would be 25 percent of the sample. The fourth week would be 12.5 percent of the original sample.
How many milligrams of a 15.0 mg sample of radium-226 remain after 6396 years if the half-life of radium-226 is 1599?
One sixteenth of a gram. 1st halflife- 1/2 gram 2nd, 1/4 3rd 1/8th 4th halflife, 1/16th
How much cesium would remain from a 10 g sample after 2 years?
5g would remain
What does not change when a physical change in a sample occurs?
Substance in the material Remain the same
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.
What fraction of a radium sample will remain after 3240?
The answer depends on 3240 WHAT: seconds, days, years?
How much of an 800-gram sample of potassium-40 will remain after 3.910000000000 years of radioactive decay?
Approximately 400 grams of the potassium-40 sample will remain after 3.91 years, as potassium-40 has a half-life of around 1.25 billion years. This means that half of the initial sample would have decayed by that time.
