Chapter 4, Problem 13CC

To determine

(a)

To state:

The half-life $h$, if initial mass of radioactive substance is $m_0$, the half-life of the substance is $h$ and $m\left(t\right)$ is the mass remaining at time $t$.

To determine

(b)

To find:

The formula for $m\left(t\right)$ in terms of half-life $h$, if initial mass of radioactive substance is $m_0$, the half-life of the substance is $h$ and $m\left(t\right)$ is the mass remaining at time $t$ .

To determine

(c)

To find:

The formula for relative rate of decay $r$ in terms of half-life $h$, if initial mass of radioactive substance is $m_0$, the half-life of the substance is $h$ and $m\left(t\right)$ is the mass remaining at time $t$ .

To determine

(d)

To find:

The formula for $m\left(t\right)$ in terms of relative rate of decay $r$, if initial mass of radioactive substance is $m_0$, the half-life of the substance is $h$ and $m\left(t\right)$ is the mass remaining at time $t$ .
