Final answer:
The ratio of the strengths of the weak and electromagnetic forces is typically around 1.0 × 10⁻ᵉ, though the specific value can vary and needs confirmation from a reliable source. This ratio underscores the substantial difference in strength between these two forces.
Step-by-step explanation:
The question asks to find the ratio of the strengths of the weak and electromagnetic forces under ordinary circumstances. In physics, the weak force, also known as the weak nuclear force, is responsible for the radioactive decay of subatomic particles and is involved in the process of nuclear fusion that powers the sun.
On the other hand, the electromagnetic force is one of the four fundamental forces and governs the interactions of charged particles.
Under normal conditions, the weak force is much weaker than the electromagnetic force. The typical value for the ratio of the strength of the weak force to the electromagnetic force is approximately 1.0 × 10⁻ᵉ, which is not listed among the provided options.
Without the specific values usually taken from a reliable source, it's improper to state the precise ratio. However, in a broad sense, the ratio highlights the significant difference in strength between these two fundamental forces.
