Which of the following statements explains one way that oceans influence the temperature of the tropics and poles? The oceans do not influence the temperature of the tropics and the poles.
The oceans distributes the even heating of the Sun. The tropics receive equal heat as the poles and the oceans keep the heat in place.
The oceans redistribute the uneven heating of the Sun. The tropics receive more direct heat than the poles, but the oceans absorb heat and take it to other parts of the globe.
The oceans help to keep the tropics warm by bringing more rain to the tropics.

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.
