the half-life of tritium, or hydrogen-3, is 12.32 years. after about 37 years, how much of a sample of tritium will remain unchanged? a)1/8    b)1/4  c)1/3  d)1/2

The correct option is A) 1/8

half-life of tritium, or hydrogen-3, is 12.32 years.      

After about 37 years,

= 37/12.32

= 3

means 3 half lives.

sample of tritium that will remain unchanged will be:

= 1/2^no.of half lives

= 1/2³

= 1/2 x 1/2 x 1/2 = 1/8

1/8 remains back

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
