(a)
Interpretation:
The equivalency and both conversion factor a) minutes and seconds is to be stated.
Concept introduction:
Equivalency is defined as the two quantities that are equivalent in value. For example: 0.025 furlong is equal to 1 rod. In this case, furlong and rod represent the same physical length but expressed in various units. When an equivalency is denoted as a fractional value it is called ‘conversion factor’. Moreover, two conversion factors result from each equivalency.
Answer to Problem 19E
The equivalency of a) minutes and seconds is
Conversion factors of a) minutes and seconds are given by;
Explanation of Solution
The two quantities that are equivalent in value is denoted as equivalence. For example:
In the expression (1), the conversion factor
A proportionality constant, m is inserted to convert a proportionality into an equality. Such as,
Given expression;
a) Minutes and seconds
Based on the above discussion the equivalency and conversion factors are states as follows;
The equivalency of a) minutes and seconds is
Conversion factors of a) minutes and seconds are given by;
Thus, the equivalency and both conversion factor a) minutes and seconds is to be stated

- Technetium is the first element in the periodic chart that does not have any stable isotopes. Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away).
