8 0

When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores

1/2 (150 N/m) (0.030 m)² = 0.0675 J

of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores

1/2 (150 N/m) (0.060 m)² = 0.27 J

Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J

Nadya [2.5K]

The thing that can be said if world statues were often believed to have had an ambiguous, porous relationship to life is: Statues could stand in for the bodies of dead individuals in rituals and ceremonies.

<h3>What is a Statue?</h3>

This refers to the monument or sculpture that is made to venerate or honor a person; living or dead.

Hence, we can see that based on the ancient use of world statues, it was believed that they had an ambiguous, porous relationship to life and thus, it can be surmised that statues could stand in for the bodies of dead individuals in rituals and ceremonies.
