The following map was created using modern technology to determine the overall temperature of the oceans. What can be concluded about the salinity of the areas near the equator? The polar regions increase salinity because the water is frozen.

O The cooler waters decrease the salinity of the water near the equator.

O Evaporation rates of warm waterincrease, which increases the salinity of water.

Warmer waters cause evaporation to be slowed down, which decreases salinity of water.​

hypothesising or postulating

that would be because of both gravity and friction. so     c

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.
