Question

the process of radioactive decay is unpredictable and irreversible. which option would be an appropriate model of the radioactive decay of a group of atoms? (1 point)
popping a bag of popcorn
petals falling from a flower
throwing tennis balls over a fence
breaking off pieces of wet clay

Explanation:

Radioactive decay is random and non - reversible. Popping a bag of popcorn is also a random process where individual kernels pop at unpredictable times and once popped, they cannot be un - popped, similar to radioactive decay. Petals falling from a flower, throwing tennis balls over a fence, and breaking off pieces of wet clay are not as random and non - reversible in the same sense as radioactive decay.

Answer:

popping a bag of popcorn
