A cylinder with a piston holds 0.50 m3 of oxygen at an absolute pressure of 4.0 atm. The piston is pulled outward, increasing th

e volume of the gas until the pressure drops to 1.0 atm. If the temperature stays constant, what new volume does the gas occupy?

Answer:

2 cubic meters

Explanation:

Suppose ideal gas, when the temperature stays constant, then the product of pressure and volume is the same as before

P_1V_1 = P_2V_2

where P_1 = 4 atm, V_1 = 0.5m^3 are the pressure and volume of the gas before. P_2 = 1 atm, V_2 are the pressure and volume of the gas after. We can solve for the volume after

V_2 = \frac{P_1V_1}{P_2} = \frac{4*0.5}{1} = 2 m^3

a baseball pitcher throws a fastball at 98 mph. he also has a slower "changeup" pitch, 75 mph, which he throws identically, same
notsponge [240]

Answer:

For these reasons at 98 mph the path is straighter

Explanation:

To solve this problem we are going to use the kinematic equations, specifically those of projectile launches, let's calculate the distances that the ball travels

     

          X = Vox t

          Y = Yo +  Voy t - ½ g t²

They tell us that the only parameter that changes is the speed, so the distance to the plate is known

          t = Vox / x

 

We replace

         Y- Yo = Voy (Vox / X) - ½ g (Vox / x)²2

       Y -Yo = Vo² sinθ cos θ / x - ½ g Vo² sin²θ / x²

        Y -Yo = Vo² (sinθ cosθ / x - ½ g sin²θ / x²)

The trajectory will be flatter when Y is as close as possible to Yo, when examining the right side of the equation, the amount in Parentheses is constant and to what they tell us that the angles and the distance the plate does not change.

Consequently, of the above, the only amount changes is the initial speed if it increases the square of the same increases, so that the height Y approaches the height of the shoulder, that is, DY decreases. For these reasons at 98 mph the path is straighter

What social science, which deals with the behavior and thinking of organisms, differs from sociology primarily in that it focuse
Svetlanka [38]

Answer : The correct answer is- Psychology.

As per the American Psychological Association, psychology can be described as the scientific study of mind and behavior of a particular individual.


There are primarily four goals of psychology that are to describe, to explain, to predict, and to control the  mental processes as well behavior of a person.

On the contrary, sociology focuses on behaviour of group of individuals. It is the study of structure, function as well as development of society.


Thus, psychology is the right answer to the question.

Why do we see ourselves in the mirror?
Arlecino [84]
You can see yourself in a mirror because light rays<span> bounce off its shiny surface. Light rays come from everything you can see, including yourself. You see things when </span>the light<span>rays from them enter yours eyes. Some of the light rays that come from yourself strike the mirror. The mirror reflects the rays because it is very smooth. The rays come back to your and enter your eyes.</span>
