A cylindrical capacitor is made of two concentric cylinders. The inner cylinder has radius r1 = 4 mm, and the outer one a radius r2 = 8 mm. The common length of the cylinders is L = 150 m.
 
  What is the potential energy stored in this capacitor when a potential difference V = 4 V is applied between the inner and outer cylinder? A)
 
  9.6  10-8 J
  B)
 
  1.3  10-8 J
  C)
 
  6.3  10-8 J
  D)
 
  0.34  10-8 J
  E)
 
  4.6  10-8 J

Question 2

Consider two cylinders of gas identical in all respects except that one contains O2 and the other He. Both hold the same volume of gas at STP and are closed by a movable piston at one end.
 
  Both gases are now compressed adiabatically to one-third their original volume. Which gas will show the greater temperature increase?
  A)
 
  the O2
  B)
 
  the He
  C)
 
  Neither; both will show the same increase.
  D)
 
  It's impossible to tell from the information given.

Over time, chronic hepatitis B virus and hepatitis C virus infections can progress to advanced liver disease, liver failure, and hepatocellular carcinoma. Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease. When combined with hepatitis B, hepatitis C now accounts for 75% percent of all cases of liver disease around the world. Liver failure caused by hepatitis C is now leading cause of liver transplants in the United States.
