The human eye can change the shape of its crystalline lens, and thus modify the lens strength (a. k.a., lens power) of the eye in order to bring things at different distances from the observer into sharp focus on its retina. If the total effective lens strength (a. k.a., lens power) of a human's eye at a particular moment is 53.0 D, how far from the eye is the object that is currently in focus on the retina

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
