Sound would be affected if there was no matter to vibrate, and there would be no sound.
option B is the correct answer.
What is mechanical wave?
Mechanical wave is a type of wave that requires material medium for its propagation.
That is, for mechanical wave to be effective, there must be a material medium for its propagation.
The examples of mechanical wave include the following;
water waves, sound waves, and seismic waves.The above mentioned examples of mechanical wave requires material medium for their propagation.
Thus, a sound wave which is an example of mechanical wave will be affected in the absence of material medium for their propagation.

how is the period of time during which the marble is being flicked completely different from the rest of the trip?
The marble is being flicked during a very short period of time compared to the rest of the trip. The marble is accelerating during this time, so its velocity is changing. The rest of the trip, the marble is not accelerating, so its velocity is constant
What is the marble's velocity?
The marble's velocity might vary from 3 m/s to 9 m/s.The length and speed of a marble's motion are measured after that, using the formula Speed = Distance / Time to determine their speed.The marble travels at its fastest speed just before it lands because that is when its potential energy changes the most, while other factors have lost the least energy up to that point.To learn more about marble velocity, follow the link https://brainly.com/question/16978117
