An electron is accelerated from rest through a potential difference. After acceleration the electron has a wavelength of 880 nm.
 
  What is the potential difference responsible for the acceleration of the electron? (h = 6.626  10-34 J  s, melectron = 9.11  10-31 kg, e = 1.6 10-19 C)
  A) 1.7  10-6 V B) 2.5  10-6 V C) 1.9  10-6 V D) 2.2  10-6 V

Question 2

A 12-V battery is connected across a 100- resistor. How many electrons flow through the wire in 1.0 min? (e = 1.60  10-19 C)
 
  A) 1.5  1019
  B) 2.5  1019
  C) 3.5  1019
  D) 4.5  1019
