How many more years worth of hydrogen does the sun have left?
The sun has about 5 billion years worth of hydrogen left before it exhausts its supply and evolves into a red giant star.
What is the Sun's life span?
G2 stars like the Sun live about 10 billion years. Our Sun is about 4.5 billion years old, so it has another 5 billion years left.
If a radioactive isotope had a half - life of 1 billion years how much of it would be left after 2 billion years?
1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years.
If a radioactive material has a half-life of 10 years what fraction of the material will remain after 30 years?
One eighth would be left.
In your opinion how exactly long do you think the year was 2 billion years ago?
In my opinion, I think the years were longer than they are now 2 billion years ago. No one will really ever know since there is no calendars that have been left behind from 2 billion years ago.
What is the original part of the bore left after rifling?
When rifled, the rifling tool cuts the GROOVES. Material left between the grooves is the LANDS.
How much of an element is left after 2 half lives?
Depends on how many grams you started with, but obviously if half decays, half is left.
How old is a fossil that has a radioactive material with a half life of 200 years if there is 25 percent of the original radioactive material left?
The fossil would be approximately 600 years old. We can calculate this by determining how many half-lives have passed based on the remaining 25% of the original radioactive material. Since the half-life is 200 years, and with 25% remaining, it means two half-lives have passed (50% after first, 25% after second). Therefore, 2 x 200 = 400 years.
What will be the reason to the end of the sun?
most likely, the end of the sun would be because of its age. it only has about 4 billion years left. A star's lifetime is about 15-20 billion years.
How long has life on earth?
2 seconds my friend did that there 5 billion years left or so
How long can the earth last?
half a billion years left. But that does not mean that PEOPLE will last that long. ;-)
When will the earth come to a end?
The planet has a few billion years left on it. As for the creatures riding it, who knows.
