The Concept of Tension in Physics

What is the tension in a rope when the elf, Sneezy, hangs from it at the North Pole?

A. 455 N

Answer:

The tension in the rope when the elf, Sneezy, hangs from it at the North Pole is 455 N.

The concept of tension in physics refers to the force transmitted through a rope or similar object when it is pulled tight. In the scenario provided, the elf, Sneezy, hanging from a rope at the North Pole creates a tension of 455 N in the rope.

This tension force can be measured by observing the elongation of a spring when replacing the rope. In this case, the spring would extend a length corresponding to a force of 49.0 N, providing a direct measurement of the tension force in the rope.

Understanding tension in a rope is crucial in various physics applications, as it helps determine the forces acting on an object in equilibrium. By knowing the tension in a rope, one can calculate the weight of the object or the force needed to keep it suspended.
