There are some patients with keratoconus that have corneas that are abnormally thin and bulge out into a cone shape. Consider a patient whose eye has a moderate case of keratoconus. The refractive power of this eye’s cornea is +50 D.


Part 1.) How far in front of the patient’s eye is its' far point, assuming the eye lens is in its fully relaxed state with a refractive power of +2 D? The eye is 25 mm in diameter. Show your work, answer should be in cm or meters.

Part 2.) What is the refractive power of the contact lens you would prescribe for the patient’s eye? Show your work.

A long thin wire carrying a current I1 =10 A (out of page) is located at (0, 0) and another wire carrying a current I2 =8A (into the page) is located at (x=9cm, y=0). Find the magnitude and direction of the magnetic field due to these two currents at (x=0, y=12 cm). Your solution must include a neat diagram.

Have some fun with this one: One way to test out the power of a social norm is to break it. Without doing something so dramatic that it would be unsafe, lands you in jail, or seriously compromises your relationships, select a behavior that people practice without question and do something different that will surprise them. (For example, you could face the rear when you are in an elevator, eat a hamburger inside-out in public, wear an article of clothing...

Assuming that 1.00 L of 4% PVA solution is spread out to form a thin sheet of thickness equal to the average length of a PVA strand, calculate the total area of the liquid sheet. Then calculate the average of the sheet of solution per strand of PVA. Assuming this area is a little square, the square root of this area gives the edge length of the square which is approximately the average distance between the PVA strands. Show that...
