The elasticity of the lens decreases with age. this leads to which of the following? the elasticity of the lens decreases with age. this leads to which of the following?

a. less light getting to the retina and diminished visual acuity
b. lowered accommodation of the pupillary reflex and blurry vision
c. a clouding of the lenses known as a cataract less accommodation of the lenses and difficulty focusing on nearby objects

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
