An airplane is flying with constant speed of 300 m/s along a horizontal circle with a radius of 15,000 m.
 
  If the lift force of the air on the wings is perpendicular to the wings, at what angle relative to the horizontal should the wings be banked? A)
 
  15.1
 
  B)
 
  22.2
 
  C)
 
  31.5
 
  D)
 
  37.7
 
  E)
 
  63.0

Question 2

An ac source of period T and maximum voltage V is connected to a single unknown element. At time t = 0 the voltage is zero.
 
  At time t = T/4 the current in the unknown element is equal to zero, and at time t = T/2 the current is I = - Imax where Imax is the current amplitude. What is the unknown element? A)
 
  a resistor
  B)
 
  an inductor
  C)
 
  a capacitor
  D)
 
  an inductor or a capacitor
  E)
 
  More information is needed to identify the element.
