Explanation:
To convert java strings of text to upper or lower case, we can use and inbuilt methods To Uppercase and To lower case.
The first two lines of code will set up a String variable to hold the text "text to change", and then we print it out.
The third line sets of a second String variable called result.
The fourth line is where the conversion is done.

Explanation:
Given that,
The half-life of Barium-139 is
A sample contains nuclei.
We need to find the decay constant for this decay. The formula for half life is given by :
Put all the values,
So, the decay constant is .
