Problem

For a radioactive isotope

X

, the magnitude of the slope of a graph of

\ln N

versus time is

S

. If the decay constant of the isotope is doubled, what happens to the magnitude of the slope of the

\ln N

versus time plot? a) It becomes

4S

b) It becomes

2S

c) It becomes

\dfrac{S}{2}

d) It remains

S
