The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams

bezimeni [28]

Answer:

Nanotechnology has bring up major advances in our everyday life. For example, the use of Nanobots that are extensively used now a days in medicine to make surgeries faster and accurate. By the use of nanotechnology, major problems like cancer can be treated by using cell by cell therapy. It is also utilized in curing genetic defects. Major drug designing and drug delivery has been made easier using nanotechnology.

Nanotechnology doesn't have any visible disadvantages but there always remains a fear like introduction of some extra contaminants and toxins in the environment. But mostly i agree with use of nanotechnology for the betterment. Furthermore we don't have any more advance techniques to fight problems than this technology.
