very long
It depends on how long the tooth is in contact with the teeth. we did an experiment in school and we concluded that if a tooth was soaked in coke it would decay in 0-1 weeks when soaked in fanta it took 1-2 weeks.
Lucy's brain was approximately one-third the size of a modern human brain.
Isaac Newton's brain weighed about 1,300 grams, which is within the normal range for an adult's brain size. There is no evidence to suggest that his brain was exceptionally large or unique in any way.
The Neanderthal's brain was the same size as a modern human's brain.
The average Neanderthal brain size was about 1,600 cc, which is slightly larger than the average modern human brain size of around 1,400 cc. This suggests that Neanderthals had relatively large brains compared to their body size.
a while
Sheet metal can take hundreds to thousands of years to decay, depending on factors such as the environment and the type of metal.
132g
Nuclear waste can take thousands to millions of years to decay completely, depending on the type of radioactive material.
The fustion will take place so long as the decay time for isotopes which is ...not stable is over.
a few months
It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
it takes 1 day 17 hours and 29 minutes for orange juice to rot or decay
after the blood circulation stops how long does the brain take to die
10.76 days
About an hour
It will take twice the half-life of the radioactive material for it to decay through two half-lives. If the half-life is 1 hour, it will take 2 hours for the material to decay through 2 half-lives.
