A certain element has half life period of 30 days. Find its average life

Explanation

To find the average life of an element given its half-life period, we can follow these steps:

### Step 1: Understand the relationship between half-life and average life
The average life (T_average) of a radioactive element can be calculated using the formula:
\[ T_{average} = \frac{T_{half}}{\ln 2} \]
where:
- \( T_{half} \) is the half-life period,
- \( \ln 2 \) is the natural logarithm of 2, approximately equal to 0.693.
