Ariel Claims That a Pulse Is Described by the Equation

Question 24

Multiple Choice

Ariel claims that a pulse is described by the equation 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 x<sup>2</sup> - 6.0xt + 9t<sup>2</sup> = (x - 3.0t) <sup>2</sup>. B) Ariel,because a pulse is not an infinite wave. C) Miranda,because (x - 3.0t) <sup>2</sup> is the same as (3.0t - x) <sup>2</sup>. D) Miranda,because a pulse is not an infinite wave. E) Miranda,because   is infinite when x = 0.

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 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 x<sup>2</sup> - 6.0xt + 9t<sup>2</sup> = (x - 3.0t) <sup>2</sup>. B) Ariel,because a pulse is not an infinite wave. C) Miranda,because (x - 3.0t) <sup>2</sup> is the same as (3.0t - x) <sup>2</sup>. D) Miranda,because a pulse is not an infinite wave. E) Miranda,because   is infinite when x = 0. is infinite when x = 0.
