The Correct Answer is :\(120\)
The half-life of a radioactive nucleus is 5 years. The fraction of the original sample that would decay in 15 years is:
Let A be a 3 × 3 matrix such that \(\text{det}(A) = 5\). If \(\text{det}(3 \, \text{adj}(2A)) = 2^{\alpha \cdot 3^{\beta} \cdot 5^{\gamma}}\), then \( (\alpha + \beta + \gamma) \) is equal to:
The amount of time taken for half of a particular sample to react is known as Half-life.
We can describe exponential decay by any of the three formulas
