There is no official, certain, way of knowing what will become of the world and life as we know it in 100 years. Anything could happen, and yet, nothing could change.
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.
There are many places to find facts about life 100 years ago. You could find facts about life 100 years ago in a library.
Assuming a life expectancy of 100 years, the number of people living more than 100 years in a population of 2 billion would be zero.
Guaranteed for 100 years with a potential life expectancy of 500 years.
100 years
That sounds like an average somebody came up with on this sort of logic: Out of 100 people using steroids, 100 years of life are lost through premature death. For example, if 10 people died 5 years prematurely (total of 50 life years), and 10 died 3 years prematurely (30 life years), and 10 died 2 years prematurely (20 life years), while 70 did not die prematurely from steroids, that would be 100 years of life lost out of 100 people, or an average of 1 year per person. Whether it is accurate, I don't know; but that could be the kind of logic behind it.
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.
i think life 100 years ago was more diffuclt because you had to do more work and there was not enough time to play. one other reason might be that there was no xboxs or other video gqmes back there 100 years ago.
Inca Royalty had the life expectancy of 100 years.
It would be 20 years. That is the length of time to lose one half the isotope.
On average 25 years
about 100 years
