Final answer:
High tension wires can snap with tremendous force due to high acceleration and tension. In fishing, fishermen let fish tire out before reeling them in to reduce the acceleration needed to avoid snapping the line. High-voltage wires are held by insulators but are not insulated themselves.
Step-by-step explanation:
High tension wires that separate from anchor points can snap with tremendous force. This is because of the properties of physics that apply when a wire under tension is suddenly released. Factors such as the acceleration and tension involved are significant in these scenarios. For example, in fishing, lines can snap due to the forces involved when a fish is on the line and sudden braking is applied to the reel. Fishermen tend to let a fish swim to tire it out, requiring a smaller acceleration to bring it in, decreasing the likelihood of the line snapping.
In relation to question 16, it is true that high-voltage wires are held aloft by insulating connectors, but they are not actually wrapped in an insulating material; they are typically bare due to the high elevation and isolation from contact. Therefore, the answer to question 16 is false.
