Exhibit 13-1
  Two blocks of masses m1 and m2 are connected by a light cord that passes over a pulley of mass M, as shown. Block m2 slides on a frictionless horizontal surface. The blocks and pulley are initially at rest. When m1 is released, the blocks accelerate and the pulley rotates.
 
 
 
  Use this exhibit to answer the following question(s).
  Refer to Exhibit 13-1. The total angular momentum of the system of the two blocks and the pulley relative to the axis of rotation of the pulley is
   
  a.
  proportional to the radius of the pulley.
   
  b.
  proportional to the speed of the blocks.
   
  c.
  proportional to the length of the string.
   
  d.
  to all of the above.
   
  e.
  only to (a) and (b) above.

Question 2

Exhibit 13-1
  Two blocks of masses m1 and m2 are connected by a light cord that passes over a pulley of mass M, as shown. Block m2 slides on a frictionless horizontal surface. The blocks and pulley are initially at rest. When m1 is released, the blocks accelerate and the pulley rotates.
 
 
 
  Use this exhibit to answer the following question(s).
  Refer to Exhibit 13-1. The total angular momentum of the system of the two blocks and the pulley relative to the axis of rotation of the pulley is
   
  a.
  the same at all times.
   
  b.
  proportional to l1, the length of string from the pulley to m1.
   
  c.
  proportional to l2, the length of string from the pulley to m2.
   
  d.
  conserved because the Earth doesn't move.
   
  e.
  proportional to the speed of the blocks.

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.
