Question

question 6 of 30 which of the following is an ongoing reaction that does not multiply exponentially? a. nuclear fusion b. a controlled nuclear chain reaction c. nuclear decay d. an uncontrolled nuclear chain reaction

Explanation:

Nuclear decay is a spontaneous process where unstable nuclei decay over time, following exponential decay (N(t) = N₀e^(-λt)), which involves a decrease, not multiplication. It is ongoing and does not exhibit exponential multiplication. Other options: A (fusion) is steady but not a multiplying reaction; B (controlled chain reaction) involves controlled multiplication; D (uncontrolled chain reaction) multiplies exponentially.

Answer:

C. Nuclear decay
