37.1×10−8M is the concentration of pb 2 ions in a solution prepared by adding 5. 00 g of lead(ii) iodide to 500. ml of 0. 150 m ki? [ k sp(pbi 2) =1. 4 × 10 –8] by common ion effect.
A phenomenon known as the "common ion effect" allows for the modification of a salt's molar solubility by adding another salt in which one ion dissociates in solution and maintains equilibrium with the undissociated salt.
The term "common-ion effect" describes the reduction in solubility of an ionic precipitate caused by the addition of a soluble molecule that shares an ion with the precipitate to the solution. Le principle for the equilibrium response of ionic association/dissociation leads to this behavior.

Answer:
Most likely Potential Energy
Explanation:
This is possible because potential energy is stored energy that an object contains until moved, once moved it transfers its potential energy into kinetic energy. In this problem, the kinetic energy in the torch is changed into potential energy once placed on the shelf and deprived of movement. Thus your only viable answer is Potential energy!
