If the work function of a metal surface is 2.20 eV, what frequency of incident light would give a maximum kinetic energy of 0.25 eV to the photoelectrons ejected from this surface? (1 eV = 1.60  10-19 J, h = 6.626  10-34 J  s)
 
  A) 2.50  1014 Hz
  B) 3.53  1014 Hz
  C) 5.92  1014 Hz
  D) 2.05  1014 Hz
  E) 1.02  1014 Hz

Question 2

A 6.0-F air-filled capacitor is connected across a 100-V potential source (a battery). After the battery fully charges the capacitor, it is left connected and the capacitor is immersed in transformer oil, which has a dielectric constant of 4.5.
 
  How much additional charge flows from the battery onto the capacitor during this process?
  A) 1.2 mC B) 2.1 mC C) 2.5 mC D) 1.7 mC
