The half life of a radioactive substance is defined as the time in which the number of radioactive nuclei becomes half of the initial number of radioactive nuclei. In the given graph we note that at time t=0 hours, there are 500000 radioactive nuclei. The half life is the time in which the number of radioactive nuclei becomes half of 500000 which is 250000.
250000 lies between 200000 and 300000. If we draw a horizontal line at 250000, the time corresponding to the point where the horizontal line intersects the given curve is the half life of the nuclei.
From the above graph we conclude

Queuing Exercise 1 Suppose you are operating a medical care center for a large factory. Workers come to the center if they become ill during working hours or if they have an accident requiring medical care. Table below is a history of 30 workers arriving at the clinic over a period of about eight hours.

Topic 7.1 – Discrete energy and radioactivity
The energy level diagram for a hydrogen atom is shown. The following questions are about the energylevels of the hydrogen atom. An electron jumps from the n = 5 level to the n = 1 level.1. Will this result in an emission line, or an absorption line in thespectrum of this atom? 1. _________________2. Which excited state did the electron start at?2. _________________3. What is the principal quantum number of the electron when it isat the level n = 1?...
