Chapter 16.1, Problem 40E

(a)

To determine

To calculate: The period of radioactivity if the activity of radio emission from the sun is $F\left(t\right)=49.6\sin \left[0.602\left(t-1.48\right)\right]+111$ where, $F\left(t\right)$ is the flux of solar emissions at time t and t is the time since January $1,1997$.

(b)

To determine

To calculate: The maximum and minimum flux of radio emissions observed in the radioactivity if the activity of radio emission from the sun is $F\left(t\right)=49.6\sin \left[0.602\left(t-1.48\right)\right]+111$ where, $F\left(t\right)$ is the flux of solar emissions at time t and t is the time since January $1,1997$.

(c)

To determine

To calculate: The time period when the radioactivity is expected to reach the first low point beyond $2012$ if the activity of radio emission from the sun is $F\left(t\right)=49.6\sin \left[0.602\left(t-1.48\right)\right]+111$, where, $F\left(t\right)$ is the flux of solar emissions at time t and t is the time since January $1,1997$.
