Two blocks are arranged as shown and kept at rest by holding the 1 kg block in place.
 
   
 
   
 
   The tension in the string is closest to:


  1.9 N
  2.10 N
  3.11 N
  4.12 N
  5.13 N
  6.10 N at the left end; 12 N at the right
  7.10 N in the left segment; 11 N in the middle segment; 12 N in the right segment
  8.Smoothly varying from 10 N by the left block to 12 N by the right block
  9.None of the above
  10.Impossible to determine

Question 2

Consider the three situations below, labeled A, B, and C. Ignore friction.
 
   
 
   After each system is released from
   rest, how do the tensions in the
   strings compare?


  1.A = B = C
  2.B = C < A
  3.A = C < B
  4.A < B < C
  5.A < C < B
  6.B < A < C
  7.B < C < A
  8.C < A < B

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
