Answer:
The half-life of the substance is 19.47 years.
Step-by-step explanation:
The equation for the amount of substance remaining is given by the following equation:
In which Q(t) is the amount remaining after t years, Q(0) is the initial amount and r is the rate that this amount decreases.
A sample of a radioactive substance decayed to 96.5% of its original amount after a year.
This means that
We use this to find r. So
So
(a) What is the half-life of the substance?
This is t when Q(t) = 0.5Q(0). So
The half-life of the substance is 19.47 years.
