Calculate the current through a 10.0-m long 22-gauge nichrome wire with a radius of 0.321 mm if it is connected across a 12.0-V battery. The resistivity of the nichrome is 1.00  10-6   m.
 
  A) 30.9 A B) 61.8 A C) 0.776 A D) 0.388 A

Question 2

A beam of light is polarized in a vertical plane and has an intensity I0. The beam passes through an ideal polarizer and then through an ideal analyzer whose axis is set horizontally.

  B) 0.25
  C) 0.31
  D) 0.37
  E) 0.43
