The highest-mass stars have the shortest lifetimes; a star 60 times as massive as the Sun is predicted to have a lifetime of only a few million years, and extremely massive stars like R136a1 have even shorter lifetimes. In contrast, small, cool, dim stars can burn for a very long time; the smallest red dwarf stars may last for a trillion years before burning out.
well i dont know
The larger a star the shorter the lifetime because, larger stars burn out more quickly.
The ozone is expected to deplete more. It is because of the use of CFC's.
Almost all stars fall in a mass range of
11.7 -15.5
False. Stars rotate faster than expected. This makes us assume there is a lot of dark matter.
Live Mas that is your hint to who I am
Lifetimes range from a few million to 100 trillion years
The larger a star the shorter the lifetime because, larger stars burn out more quickly.
When a star is at the end of its lifetime its mass increases.
10 years
The clock / BIOS battery found in most desktops has an average lifetime of 5 to 7 years. While this is certainly not the expected lifetime of the user, it is about the same as the expected useful lifetime of a desktop.
Many truckcompanies operate with half a million miles as a lifetime goal.
Red dwarves.
The chemicals (usually hydrogen and helium) that fuel the reactions in the star that creates heat and light have a finite lifetime. Our own sun is expected to only last for about another 6,000 years.

A person can be expected to breath in approx. 48 pounds of dust in a lifetime.
