question 47

Multiple Choice

Let P(t) be the quantity of strontium-90 remaining after t years. Suppose the half-life of strontium-90 is 28 years. Which of the following equations expresses the half-life information?

• A) P(28) = \(\frac { 1 } { 2 }\) \(\mathrm { P } _ { 0 }\)
• B) P \(\frac { 1 } { 2 }\) = 28 \(\mathrm { P } _ { 0 }\)
• C) 28 = \(\frac { 1 } { 2 }\) \(\mathrm { P } _ { 0 }\)
• D) 28 = \(\frac { 1 } { 2 }\) \(\mathrm { P } _ { 0 }\) \(\mathrm { e } ^ { - \mathrm { kt } }\)
• E) none of these
