Answer:
Topographic maps generally shows Natural features such as Rivers and Lakes.
sometimes they also show some features made by humans like brodges, elevations etc.
Radioactive material undergoes first order dissociation kinetics.
For 1st order system,
k = 0.693 / t1/2
where, t 1/2 = half-life of the radioactive disintegration process.
Given that, t 1/2 = <span>73.83 days
Therefore, k = 0.009386 day-1
Also, for 1st order reaction,
k = </span>

Given that, Co = initial concentration of <span>Iridium-192 = 100 g
Therefore, </span>0.009386 =

On rearranging we get,
Ct = 100
Answer: Ct = 100

equation approximates the amount of Iridium-192 present after t days
Answer:
7.44 C is the answer of the question.
