Satellite technology has allowed us to monitor areas that were once so remote that we had no way of monitoring them. Review the statements and choose the one that best describes how we can use this technology to benefit the environment.

North American forests and their ecosystems are some of the most important and difficult to monitor. Satellite surveillance allows us to detect fires in these remote areas and direct firefighting activities early so fires can be quickly contained.
Satellite surveillance has been a great help in the war against smugglers. Law enforcement officials are able to use satellites to track and predict the activities of smugglers. We are all safer because of satellite surveillance.
Satellite surveillance helps us identify the different types of vegetation that cover remote areas. We can then record and catalog the different types of grasses, bushes, and trees.
Satellites can help us monitor weather conditions all over the world. This can help travelers plan for the weather when they are traveling to other states or countries.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

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.
