One of the dangers of tornados and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume that the air pressure inside of a sealed house is 1.02 atm when a hurricane hits.
 
  The hurricane rapidly decreases the external air pressure to 0.910 atm. A square window in an outside wall of the house measures 2.02 m on each side. What net force (directed outwards) is exerted on this window? (1 atm = 1.01  105 Pa.)
  A) 5.37  105 N B) 5.14  104 N C) 4.53  104 N D) 4.78  105 N

Question 2

What must be the diameter of a cylindrical 120-m long metal wire if its resistance is to be 6.0 ? The resistivity of this metal is 1.68  10-8   m.
 
  A) 0.65 cm B) 0.65 mm C) 0.0325 mm D) 0.065 mm E) 0.325 mm
