Hope it helped you.
My name is Charlie.
Today this question is about science,or chemistry.
A. Acceleration is a correct answer. Acceleration is a rate of change in velocity.
It change in velocity/change in time. Next, to slope will be indicated by the acceleration.
B Change in position is a incorrect answer.
C. Velocity is a incorrect answer. Velocity is a displacement of an object during a specific unit of time. It can used two measurements are needed to determine velocity. It displacement or by the time. Displacement it includes a direction, so the velocity will also includes a direction. It can used speed with direction. Velocity it can be average velocity or an instantaneous velocity.

Answer:
A
Explanation:
A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.
Answer:
A) M
Explanation:
The three blocks are set in series on a horizontal frictionless surface, whose mutual contact accelerates all system to the same value due to internal forces as response to external force exerted on the box of mass M (Newton's Third Law). Let be F the external force, and F' and F'' the internal forces between boxes of masses M and 2M, as well as between boxes of masses 2M and 3M. The equations of equilibrium of each box are described below:
Box with mass M
Box with mass 2M
Box with mass 3M
On the third equation, acceleration can be modelled in terms of F'':
An expression for F' can be deducted from the second equation by replacing F'' and clearing the respective variable.
Finally, F'' can be calculated in terms of the external force by replacing F' on the first equation:
Afterwards, F' as function of the external force can be obtained by direct substitution:
The net forces of each block are now calculated:
Box with mass M
Box with mass 2M
Box with mass 3M
As a conclusion, the box with mass M experiments the smallest net force acting on it, which corresponds with answer A.
<span>The heliocentric model of the
universe was proposed by Nicolaus Copernicus. There are numerous scientist in
ancient times who try to explain what happens in the universe. He may not be
the first one who proposed that what astronomical body is the center of the
universe. However, he stated that the center of the universe was the sun, not
the earth. And the earth revolves around it. It is in his book on the
Revolutions of the Heavenly Bodies. It was only published as he lay in his
deathbed. </span>
