Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure.
Testable: Able to be tested or tried.
<em>ex. An example of a testable hypothesis is, Students who attend class more have higher grades, while those who skip have lower grades. </em>
Data: Data is the items of information that represent our analyze, or our findings in an experiment.
<em>ex. An example of Data, is the results of information collected for a research paper.</em>
Evidence: Evidence is information that helps show whether a proposed idea is valid.
<em>ex. We can use evidence to help support our point and strengthen our findings with reasoning.</em>
Theory: Theory is an explanation of something in the natural world that can be tested and gives us the same results each time. A proven hypothesis.
<em>ex. Examples of scientific theories are gravitation, evolution, and plate tectonics. </em>
Hypothesis: A hypothesis is a theory or question that can be tested through study and experimentation. It has more reasoning to it than a simple guess, but not enough information to be a theory.
<em>ex. An example of a possible hypothesis is, If we play music while working on homework, the participant's perfomance will increase.</em>
A=(v2-v1)/t
v2=0,6m/s
v1=2,4m/s
t=4s
a=(0,6-2,4)/4=-1,8/4=-0,45 m/s^2
Answer:
The magnitude of the acceleration is 
The direction is 
i.e the negative direction of the z-axis
Explanation:
From the question we are that
The mass of the particle 
The charge on the particle is 
The velocity is 
The the magnetic field is 
The charge experienced a force which is mathematically represented as
Substituting value
Note :
Now force is also mathematically represented as
Making a the subject
Substituting values
The statement “All of the earth's life and weather exists
within the stratosphere” is false. The answer is letter B. The answer is the
troposphere. The first layer, troposphere, is where we are able to do most of
our activities. This is where we can see the formation of clouds, the
production of rain, hail, snow and other weather phenomenon. Also, this layer
is where the greatest amount of air pressure because most of the molecules of
air are in this area. Like us, air has also mass and the pressure is brought
down by the earth’s gravity causing an increase in weight exerted on you as you
descend lower into the atmosphere. So, as you enter into the other layers of
atmosphere above the troposphere, the air pressure starts to decrease. <span>Below the
atmosphere is the hydrosphere. This is where all liquid forms are located. And
since the seawater has a greater mass than air, it has the greatest
pressure. </span>
