A series circuit contains an 80-F capacitor, a 0.020-H inductor, and a switch. The resistance of the circuit is negligible.
 
  Initially, the switch is open, the capacitor voltage is 50 V, and the current in the inductor is zero. At time t = 0 s, the switch is closed. When the potential across the capacitor is 30 V, what is the rate of change of the current?
  A) 1000 A/s
  B) 1500 A/s
  C) 2000 A/s
  D) 2500 A/s
  E) 3000 A/s

Question 2

If a 2.0-MeV neutron released in a fission reaction loses half its kinetic energy in each moderator collision, how many collisions are needed to reduce its kinetic energy to 1/25 eV?
 
  A) 6
  B) 18
  C) 26
  D) 30
  E) 4
