Atoroid having a square cross section, 5.00 cm on a side, and an inner radius of 15.0 cm has 500 turns and carries a current of 0.800 a. (it is made up of a square solenoid—instead of a round one as in fig. 29-17—bent into a doughnut shape.) what is the magnetic field inside the toroid at (a) the inner radius and (b) the outer radius?

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?
