Final answer:
A long and flexible pole carried by wire-walkers enhances stability by increasing the moment of inertia, offering greater resistance to rotational motion changes and thereby aiding the walker in maintaining balance.
the correct answer to the question at hand is (c) Enhances stability.
Step-by-step explanation:
The long and flexible pole carried by wire-walkers serves to enhance stability. By carrying a pole, the wire-walker increases the moment of inertia, which means there is a greater resistance to a change in the rotational motion.
This makes it easier for the wire-walker to balance and stay upright.
The pole does not significantly affect the angular momentum unless the walker is actively rotating it. It also does not directly reduce tension; tension in the wire is caused by the weight of the walker and the pull of the supports. Therefore, the correct answer to the question at hand is (c) Enhances stability.
