Final answer:
In a physics context, size and strength often relate to the magnitude of force, which is relevant in scenarios requiring physical exertion but not generally for modern skilled jobs.
Step-by-step explanation:
The question regarding size and strength for jobs is a little ambiguous as it lacks context. However, in a physics context, the strength often relates to the magnitude of force an object or material can withstand or exert. For instance, in comparing different forces acting on objects, we can make statements such as 'The magnitude of force A must be greater than the magnitude of force B', implying A > B, or 'The magnitude of force A must be equal to the magnitude of force B', indicating A = B.
In certain job scenarios, the size and strength of a person or object can indeed matter, especially in tasks that require physical exertion. An illustrative example could be a construction worker lifting heavy materials where greater physical strength would be beneficial. However, for many modern jobs, size and strength are less relevant compared to skills, knowledge, and experience.
