The statement that accurately describes a proper use of eyeglasses is statement A. Using converging lenses to help a nearsighted person by moving the image from in front of the retina to the retina.
energy never disappears, for example, if you give some kinetic energy to a ball and it stops few seconds later, friction steals this energy to ground which ball was going on. "Law of Conservation of Energy" tell us that energy can't disappear

In explanation, chemical property is a
characteristic of a certain substance came from an outcome due to chemical change
or reaction. In the situation above, more specifically toxicity is involved in
the chemical property/change. Hence, when the object is tested for
decomposition. Like for an example of decomposition simply in metals, rusting. Rusting
a process of degeneration of metals. Here it works the same. Toxicity is how
much damage did a certain entity do to the object. </span>
