A"biconvex" lens is one in which both surfaces of the lens bulge outwards. suppose you had a biconvex lens with radii of curvature with magnitudes of |r1|=10cm and |r2|=15cm. the lens is made of glass with index of refraction nglass=1.5. we will employ the convention that r1 refers to the radius of curvature of the surface through which light will enter the lens, and r2 refers to the radius of curvature of the surface from which light will exit the lens. c) what is the focal length of the lens if it is immersed in water (nwater = 1.3)f= cmwhat is the focal length f of this lens in air (index of refraction for air is nair=1)?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.
