What is the half-life of candium? (i. e., what number of shakes are necessary to reduce the radioactive members to one-half? )

Half-life is the length of time required for one half of an isotope to decay.

Explanation:

In the following experiment, half-life of candium is 10 seconds. At the end of the activity, 1/4th of the sample remained and 3/4th got decayed. The decay of radioactive elements occurs at a fixed rate.

1. If you place 50 atoms of candium (candy) in the bag.

2. Then after sealing the bag, shake it for 10 seconds.

3. Gently take out the candy.

4. The number of candies with the print side up are the atoms which are decayed. And keep the pieces with printed side down back in the bag.

5. Continue this activity until all the atoms have decayed.

Thus, in this activity, half-time is 10 seconds as we shook the bag for 10 seconds.

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.
