2. Scientists claim that the ocean floor has magnetic pattems. Why does this support the theory of plate tectonics? A. Magnetic patterns are symmetrical on each side of the mid-ocean ridge, which would indicate that the seafloor is spreading apart like the tectonic plate theory claims.
B. Magnetic patterns can only form after billions of years; this proves that the seafloor has not moved recently, which is what the tectonic plate theory claims. C. Magnetic patterns only form where two plates are moving together, which could be expected if the earth's crust is moving

where's the following? you gotta add it to know what the choices are

explanation:

the answer is mosques. they are an important part of islamic culture.

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.
