The figure below represents a string which has a heavy section and a light section. The mass per unit length of the heavy section is 16 times as large as the mass per unit length of the light section. When the string is under tension, the speed of a pulse traveling in the heavy section is ____ times the speed of that same pulse traveling in the light section.
 a.
  b.
  c.
  d. 2
  e. 4

Question 2

Ariel claims that a pulse is described by the equation where x and y are measured in cm and t in s. Miranda says that it is not possible to represent a pulse with this function because a wave must be a function of x + vt or x  vt. Which one, if either, is correct, and why?
 a. Ariel, because x2  6.0xt + 9t2 = (x  3.0t)2.
  b. Ariel, because a pulse is not an infinite wave.
  c. Miranda, because (x  3.0t)2 is the same as (3.0t  x)2.
  d. Miranda, because a pulse is not an infinite wave.
  e. Miranda, because is infinite when x = 0.
