Which statement best describes how a wave would move differently through a pot of boiling water than the steam created from it?

Hello. This question is incomplete. The complete question is:

"Which statement best describes how a wave would move differently through a pot of boiling water than the steam created from it? The wave would move faster through the water than through the steam. The wave would move slower through the water than through the steam. The wave would move the same speed through the water and the steam. The wave would move through the water and steam at the same speed, but decrease in speed at the transition point. "

The wave would move faster through the water than through the steam.

Explanation:

As we already know, the water molecules at the moment when the water is boiling move very fast, due to the thermal energy that acts on them. This movement causes the mileculas to collide with each other quickly, for this reason we can observe that movement of the boiling water. This makes the wave movement in the boiling water fast.

On the other hand, all this movement is not seen in water vapor molecules, since the space between them is larger and there is no energy acting directly on them. For this reason, we can say that, through steam, the wave would not move with such speed.

ok

explanation:

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.
