A mass of 385 g hangs from one end of a string that goes over a pulley with a moment of inertia of 0.0125 kgm2 and a radius of 15.0 cm. A mass of 710 g hangs from the other end.
 
  When the masses are released, the larger mass accelerates downward, the lighter mass accelerates upward, and the pulley turns without the string slipping on the pulley. What is the tension in the string on the side of the 710-g mass? A) 9.77 N
  B) 6.87 N
  C) 5.59 N
  D) 4.41 N
  E) 3.68 N

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
