A resistor is connected to a battery with negligible internal resistance. If you replace the resistor with one that has quadruple the resistance, by what factor does the power dissipated in the circuit change?
 a. 0.25
  c. 2.0
  b. 4.0
  d. 0.50

Question 2

A solid cylinder of mass 3.0 kg and radius 0.2 m starts from rest at the top of a ramp, inclined 15, and rolls to the bottom without slipping. (For a cylinder I = 0.5MR2.) The upper end of the ramp is 1.5 m higher than the lower end. Find the linear speed of the cylinder when it reaches the bottom of the ramp. (g = 9.8 m/s2)
 a. 4.7 m/s
  c. 4.0 m/s
  b. 4.4 m/s
  d. 2.4 m/s
