[Brittanyd9008]

Two solenoids, wound from wire from the same spool, have the same length and cross-sectional area, but solenoid 1 has twice the turns of solenoid 2 . If these solenoids are each connected to a circuit, and the only non-negligible resistance is that of the solenoids, which solenoid gives the greater time constant and by what factor?
 a. 2 by a factor of 2
  c. 1 by a factor of 2
  b. 2 by a factor of 4
  d. No answer above is completely correct.

Question 2

Consider the curve f(x) = A cos(2px/l). The wavelength of the wave will be:
 a. the distance 0 to A.
  c. twice the distance x2 to x3.
  b. twice the distance 0 to A.
  d. the distance x2 to x3.
