Which of the following statements are true? Check all that apply. Check all that apply. The speed of sound is constant. The pitch of a sound is determined by its frequency. The loudness of a sound is related it its amplitude. Sound is a transverse wave. Sound can travel through a vacuum.

true a y b

Explanation:

Sound is created by the vibration of air particles, it is a longitudinal wave and has several characteristics, its velocities

            v = √ B/ρ

and it fulfills the relation of the waves

           v = λ f

With these reasons, we review the claims

a) True. The speed of sound is cosecant

b) True. Tone is a function of treble, bass frequency

C) False. The intensity of the sound is proportional to the square of the amplitude

d) False. Sound is a longitudinal wave

e) False. Sound needs a material medium to travel

  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.
