Answer:

Age of the ancient wood object is 11460 years.

Explanation:

We know that half-life for carbon-14 is 5730 years. That means the activity of the sample will decrease to half every 5730 years.

Now we construct the following table:

activity (counts/min)        age of the wooden object

      40                                                  0

      20                                               5730

      10                                                11460

Describe some of the practical uses of controlled fission reactions.
Katarina [22]
By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.

2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.

Hope this helps!
