bobpursley is correct, I just took the quiz
1. The correct answer is c. They cannot represent every variable. Models and equations simplify complex phenomena by assuming certain factors are constant or disregarding certain variables altogether. This limitation means that they may not fully capture the entirety of a system or accurately represent every aspect of reality.
2. The statement is true. Radioactive material, once created, cannot be destroyed through normal chemical or physical processes. It decays over time and may transform into other elements, but it does not disappear completely.
To answer the first question, we need to understand the limitations of models and equations. Models and equations are limited because they cannot represent every variable. In complex systems or situations, there are often various factors at play that cannot be fully captured or modeled by a simple equation or model. This limitation arises due to the complexity of real-world phenomena and the inability to account for all the variables involved. Hence, the correct answer to the first question is option c, "they cannot represent every variable."
As for the second statement, "One created radioactive material cannot be destroyed," the correct answer depends on the specific context. Radioactive materials decay over time through various natural processes, so they can eventually be reduced to a stable state. However, some radioactive materials have extremely long half-lives, which means that their decay process takes an extraordinarily long time to complete. Therefore, while it is not accurate to say that radioactive material cannot be destroyed, the process of its decay may take an impractically long time for practical purposes. In this case, the correct answer to the second statement is option F, False.
