Please please help with this question.
Nearly all physics problems will use the unit m/s2 for acceleration. Explain why the seconds are squared. Why isn’t the unit given as m/s, as it is for speed?

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

the correct answer to this question is #5

answer; synapse; i believe this is correct,plz check first good luck;
