Final answer:
The scientific law depicted in the movie The Little Mermaid is the Law of Conservation of Energy, where energy is neither created nor destroyed but transforms from one form to another.
Step-by-step explanation:
The scientific law depicted in the movie The Little Mermaid that is applicable to the question is the Law of Conservation of Energy. This law states that energy cannot be created or destroyed, only transformed or transferred from one form to another. While The Little Mermaid is a work of fantasy, real-world physics applies to the concept of energy within its story. For example, the movement of sea creatures and the power of Ursula's spells can be seen as transformations of energy. However, it's important to note that the movie also includes many instances of magical and fantastical occurrences that don't adhere to actual scientific laws.The Law of Conservation of Energy is a fundamental principle in physics that is observed consistently in all closed systems, even though the movie may depict it in a very stylized manner. This law is also correlated with the first law of thermodynamics, which involves the internal energy of a system and the transfer of energy through work and/or heat, as stated in Essential Knowledge 5.B.7.
