Which value is being measured in the columns labeled fraction remaining and percentage remaining

ahrayia [7]

Question:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

years of decay
quantity of energy
number of stable atoms
amount of material that has not decayed

Answer:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

Explanation:

The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over $\frac{1}{16} th$ of the sample remained. In percentage it is 6.25%
