Physics plays a crucial role in explaining the process by which microwave ovens heat food using electromagnetic waves. Similarly, magnetic resonance imaging (MRI) uses electromagnetic waves to produce brain images that can pinpoint the precise location of tumors. Additionally, physics helps us understand the hazards of placing metallic objects near both of these devices. This is a single phenomenon in nature, so you are dependent on a A. Model B. Law C. Theory D. Principle QUESTION 2 We can understand an atom's properties because we can picture it in our minds, although we have never seen an atom with our eyes. New tools, of course, allow us to better picture phenomena we cannot see. In fact, new instrumentation has allowed us in recent years to actually "picture" the atom. Since we are contemplating phenomena that we do not typically encounter, we are discussing a Model Theory Law Principle
