d. They are a form of signal that can be heard.

Say what answer you choose.
Explain your answer.
Say why you didn't choose the other ones and instead you choose (what you think or know it is).
If you give me the correct answer and you know it is correct then I'll give brainiest to you. (only if two people answer).

seeing the graph would

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
