A half-life is the time required for one half of the atoms of a radioactive substance to decay. Do these special type of atoms continue to decay until they become stable atoms and they do not give off energy anymore?

Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive

Explanation:

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

acceleration = 18/3 = 6 m/s per second.
