the waves that move back and forth in the same direction

Explanation:

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

The waves in which the particles of medium moves in the direction of motion.sound is a longitudinal wave.it moves in all media i.e.solid,liquid,has.

Explanation:

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
