A proton of mass m is at rest when it is suddenly struck head-on by an alpha particle (which consists of 2 protons and 2 neutrons) moving at speed v.
 
  If the collision is perfectly elastic, what speed will the alpha particle have after the collision? (Assume the neutron's mass is equal to the proton's mass.) A) zero
  B) 2v/3
  C) 3v/5
  D) 5v/3

Question 2

Two experimental runs are performed to determine the calorimetric properties of an alcohol which has a melting point of -10 C.
 
  In the first run, a 200-g cube of frozen alcohol, at the melting point, is added to 300 g of water at 20C in a styrofoam container. When thermal equilibrium is reached, the alcohol-water solution is at a temperature of 5C. In the second run, an identical cube of alcohol is added to 500 g of water at 20C and the temperature at thermal equilibrium is 10C. The specific heat capacity of water is 4190 J/kg  K. Assume no heat is exchanged with the styrofoam container and the surroundings. What is the specific heat capacity of the alcohol? A) 1700 J/kg  K
  B) 1900 J/kg  K
  C) 2100 J/kg  K
  D) 2300 J/kg  K
  E) 2500 J/kg  K

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.
