Can someone answer this for me? it’s due today and i need it done asap! i will give brainlist!!

1. The sound waves are longitudinal because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

2. A pulse or a wave is introduced into a slinky when a person holds the first coil and gives it a back-and-forth motion. This creates a disturbance within the medium; this disturbance subsequently travels from coil to coil, transporting energy as it moves.  

Explanation:

1. longitudinal waves

explanation:

because the vibration of the molelecules occurs in the same direction of propagation of the wave.

2.  amplitude & frequency

explanation:

large amplitude waves contain more energy.

if more waves pass by, more energy is transferred each second.

hope this helped :) pls give me brainliest <3
