An optician is prescribing glasses for an aging professor with a near point at 43.0 cm. if the distance from the cornea-lens system to the retina is 2.5 cm calculate the focusing power "p" (in diopters) of the eye when focused at the near point. what power "p" (in diopters) would the optician prescribe in order to provide reading glasses with a book held at the standard 25 cm distance?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200Γ10^β2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
