Hannah's eyes have the same range as her sister's, with the same focal power for her cornea (50 diopters) and for her variable lens (5 diopters), but hannah suffers from myopia. she cannot focus on any object that lies more than 0.8 meters from her eyes since they are slightly longer -- the cornea to retina distance is larger -- than her sister's eyes. considering this new far point, what is the diameter of hannah's eyes (in millimeters, to the nearest tenth of a millimeter) assuming anna's eye diameter was ideally, again, 20.0 mm? hint: the focal power of the cornea remains the same for hannah as for anna for focusing distant objects, but the farthest hannah can see (object distance) changes from infinity to 0.8 meters.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
