If I = 2.0 mA and the potential difference, V_A  V_B = +30 V in the circuit segment shown, determine the charge and polarity of the capacitor.
 
   
  a.
  1.5 mC, left plate is positive
   
  b.
  1.5 mC, right plate is positive
   
  c.
  0.45 mC, left plate is positive
   
  d.
  0.45 mC, right plate is positive

Question 2

A car originally traveling at 30 m/s manages to brake for 5.0 seconds while traveling 125 m downhill. At that point the brakes fail. After an additional 5.0 seconds it travels an additional 150 m down the hill. What was the acceleration of the car after the brakes failed?

Question 3

In the circuit segment shown if I = 7 mA and Q = 50 C, what is the potential difference, V_A  V_B?
 
   
  a.
  40 V
   
  b.
  +40 V
   
  c.
  +20 V
   
  d.
  20 V
