In situation A, a bar magnet moves toward a stationary coil at a constant speed, and the maximum current is recorded. If the magnet moves again toward the coil in situation B at the same speed, from the same direction, what would explain the different current reading

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?
