gas stored in a tank at 273 k has a pressure of 50kpa. what happens to the volume when the pressure is decrease due to the added pressure

Answers

Answer 1

Answer:
I can't think of any way that pressure can be decreased due to added pressure.

Be that as it may, and it certainly still is ...

No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change. Any sample
of gas always expands to fill the container in which it's confined.
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

State the principle of transmission of pressure in liquids

Answers

Answer:

Pascal's law or the Principle of transmission of fluid-pressure states that "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same."

How to find the time in the air based off of the height and velocity

Answers

Answer:

To find time to reach maximum height given initial velocity use the equation Vf=vi+at. At the maximum height, the object has no initial velocity left and therefore you can substitute 0 for the Vf in the equation.

Tarzan swings on a 31.0 m long vine initially inclined at an angle of 36.0◦ with the vertical. The acceleration of gravity if 9.81 m/s 2 . What is his speed at the bottom of the swing if he a) starts from rest? Answer in units of m/s

Answers

Answer:

$v=10.777m/s$

Explanation:

Tarzan swing can be thought of as change in potential energy by going from higher location We solve for height of beginning of the swing by using simple cosine equation:

$31Cos36=25.08\nE_(potential)=mgh\n$

ΔE=mg(h₂-h₁)

$=m*9.81(31-25.08)\n$

The potential energy of Tarzan initial position is converted into kinetic energy of his swing.By using kinetic equation

$E_(kinectic)=P_(potential)\n1/2mv^(2)=m*9.81(31.0-25.08)\n(1/2)v^(2)=9.81(31.0-25.08)\n0.5v^(2)=58.07\nv^(2)=58.07/0.5\nv=√(58.07/0.5)\n v=10.777m/s$

Kepler discovered that planets move faster when they are closer to the sun. Which scientist discovered the reason they move faster?a. Brahe
b. Copernicus
c. Newton
d. Ptolemy

Answers

Answer;

C. Newton

Explanation;

According to Kepler, the orbital speed of a planet varies, depending on its distance from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.
While thinking on Kepler's laws, Newton realized that all motion, whether it was the orbit of the Moon around the Earth or an apple falling from a tree, followed the same basic principles.

pretty sure it was Sir Issac Newton

The Articles of Confederation established a strong national government.
a. True
b. False

Answers

It is false that the Articles ofConfederation established a strong national government. Because it wasestablished after the war. Federalists agree tothe constitution and believe that a strong central government is needed for thepreservation of the union. They focused and criticized the flaws of Articles ofConfederation and view their rivals as having no solutions. The leaders in thisgovernment are strong and well organized. Anti-Federalists on the other hand,agree to the weak federal government and fully supported the bill of rights;they further argued that the constitution being proposed by the federalistscontain no protection of the rights of the individual. They are skeptical onthe constitution as it is being influenced by the colonialism.
