While testing speakers for a concert, tomás sets up two speakers to produce sound waves at the same frequency, which is between 100 hz and 150 hz. the two speakers vibrate in phase with each other. he notices that when he listens at certain locations, the sound is very soft (a minimum intensity compared to nearby points). one such point is 26.2 m from one speaker and 37.3 m from the other. (the speed of sound in air is 343 m/s.)

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
