Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called a. longitudinal waves. b. transverse waves. c. surface waves. d. combination waves. select the best answer from the choices provided a b c d

a. Longitudinal waves

Explanation:

A longitudinal wave is a wave in which the propagation of the wave is in the same direction as the displacement of the medium carrying the wave.

It is also a type of wave in which the direction that the wave moves is parallel to the direction that the particles of the medium (which carry the wave) move.

Examples of longitudinal waves include seismic waves, and sound waves.

0.11 m/s and 0.28 m/s should be correct

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
