Answer:
Step-by-step explanation:
The different isotopes have different "half-lives" – the time it takes to lose half of its radioactivity. Pu-239 has a half-life of 24,100 years and Pu-241's half-life is 14.4 years. Substances with shorter half-lives decay more quickly than those with longer half-lives, so they emit more energetic radioactivity.
Answer:
True.
Step-by-step explanation:
It fails the vertical line test. The vertical line test checks to see if any inputs (x values) have more than one output. In this case, they do.
