Answer:
half-life = 3.8 days
total time of decay = 15.2 days
initial amount = 100. g
number of half-lives past: 15.2/3.8 = 4 half-lives
4 half-lives = 1/16 remains
100. g x 1/16 = 6.25 g
Answer:
P = 1/8
Explanation:
The wave function of a particle in a one-dimensional box is given by:

Hence, the probability of finding the particle in the one-dimensional box is:


Evaluating the above integral from x₁ = 0 to x₂ = L/8 and solving it, we have:
Solving for n=4:
