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

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
