What is the most likely reason that a hypothesis would be useful even if experiments show that it is false? new hypotheses and experiments can be developed that better fit the observations made during the original experiments. many new experiments could be designed and conducted to gather more evidence that the hypothesis is false. scientists can know that there is no relationship between the dependent and independent variables being tested. the field of study can be ignored because it has proven to be untestable by scientific standards.

 New hypotheses and experiments can be developed that better fit the observations made during the original experiments.

Explanation:

In order to reason out an observation, a hypothesis is written and and experiment is designed to test it. The result of the experiment may or may not align with the hypothesis. If the result is negative, it does no mean that the hypothesis is not useful. It means that we need to find some other relationship between the variables. In order to do so, new hypothesis and experiment needs to be developed t better suit the observations.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

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.
