What is the distance to the focus (within the eye) of a small object (e. g. a point source of light) that is on the axis of sight, 10 cm from the front of the cornea, for this eye model? Assume that the distance to focus of the light rays from this point source that enter the eye at y = 1 mm yields a good approximation of the overall distance to the focus. Next, assume that the radius of curvature of the cornea, RC, could change (much like that of the lens in an actual eye) to refocus the light on the back of the eye (i. e. use the value of fl found in part b as y  0 for the distance to the retina). What would the new radius of curvature need to be to accommodate our vision to focus on this nearby object? You may again use y = 1 mm for your math. Also assume that changing RC via accommodation does not change the distance to the back of the retina,

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
