Two identical blocks fall a distance H. One falls directly down; the other slides down a frictionless incline. Which has the larger speed at the bottom?
 
  1.The one falling vertically
  2.The one sliding down the incline
  3.Both have the same speed
  4.Cannot be determined

Question 2

Two identical blocks are pulled as shown along rough horizontal surfaces with the same coefficient of friction. Both are pulled at constant speed v. Which tension force does more work moving the block a distance D along the surface?
 
  1.T1
  2.T2
  3.Neither; both do zero work
  4.Neither; both do the same amount of negative work
  5.Neither; both do the same amount of positive work
  6.Impossible to determine without knowing the mass m
  7.Impossible to determine without knowing the speed v
  8.Impossible to determine without knowing the angle of T2
  9.Impossible to determine for 2 of the reasons above
  10.Impossible to determine for some other reason

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

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.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
