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:
The net current flowing in the given circuit is ___ A.
If the equation \( a(b - c)x^2 + b(c - a)x + c(a - b) = 0 \) has equal roots, where \( a + c = 15 \) and \( b = \frac{36}{5} \), then \( a^2 + c^2 \) 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
