Answer:

The equation it's very simple and corresponds to the ideal gas model, which is this one: P.V=n.R.T

Explanation:

Gases tend to behave following the mathematic relationship due to the ideal gas formula shown above; where <em>P</em><em> </em>is the pressure applied to a gas inside a recipient (for example), <em>V</em> is the volume of the recipient where the gas exists (that is the same volume of the gas since any gas tends to fill all the volume of a limited space of the recipient), <em>n</em> is the number of moles and indicates the amount of gas (molecules of gas) inside the recipient and <em>T</em> is the temperature of that particular gas. <em>R</em> is just a constant called <em>the gas constant </em>(8.314 JK^{-1}mol^{-1}). An ideal gas doesn't lose its internal energy over time, so the collision between the particles of the gas are considered <em>perfect elastic collisions</em>; which means that the system gas-recipient is a <em>closed physical system</em> that won't release energy to the surroundings,

Getting back to the actual question after the background: as <em>n </em>and<em> R </em>are constant, the <em>pressure </em>and <em>temperature</em> are directly correlated to each other, consider we assume <em>V </em>can't change; when the <em>T</em> drops, so does the <em>pressure </em>(think of it as the gas contracts itself because is losing excitation from the source of <em>temperature</em>). In other hand, if <em>T</em> increases, the gas will tend to expand itself so it will also increase the <em>pressure</em> (the gas is now colliding a lot inside the recipient because is gaining energy from the source of <em>temperature</em>)

a water line starts the service with an altitude of 1200m over the sea level, what is the velocity of the water above 1050 m ove
Ilia_Sergeevich [38]

Answer:

Velocity = 94.85m/s

Explanation:

<u>Given the following data ;</u>

Height = 1200m

Vertical distance = 1050m

To find the time, we would use the second equation of motion;

S = ut + \frac {1}{2}at^{2}

Substituting into the equation, we have;

1200 = 0(t) + \frac {1}{2}*9.8*t^{2}

1200 = 0 + 4.9*t^{2}

1200 = 4.9*t^{2}

t^{2} = \frac {1200}{4.9}

t = \sqrt{122.45}

t = 11.07 secs

To find the velocity;

Mathematically, velocity is given by the equation;

Velocity = \frac{distance}{time}

Substituting into the above equation;

Velocity = \frac{1050}{11.07}

Velocity = 94.85m/s

Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.

Starting from rest, a small block of mass m slides frictionlessly down a circular wedge of mass M and radius R which is placed o
guapka [62]

Answer:

Part a)

V = \sqrt{\frac{2\frac{m}{M}gR}{(\frac{M}{m} + 1)}}

v = \frac{M}{m}\sqrt{\frac{2\frac{m}{M}gR}{(\frac{M}{m} + 1)}}

Part b)

Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move

so displacement in Y direction is given as

y_{cm} = \frac{mR}{m + M}

Explanation:

PART A)

As we know that there is no external force on the system of two masses in horizontal direction

So here the two masses will have its momentum conserved in horizontal direction

So we have

mv + MV = 0

Also we know that here no friction force on the system so total energy will always remains conserved

So we have

\frac{1}{2}mv^2 + \frac{1}{2}MV^2 = mgR

now we have

\frac{1}{2}m(\frac{MV}{m})^2 + \frac{1}{2}MV^2 = mgR

\frac{1}{2}MV^2(\frac{M}{m} + 1) = mgR

so we have

V = \sqrt{\frac{2\frac{m}{M}gR}{(\frac{M}{m} + 1)}}

and another block has speed

v = \frac{M}{m}\sqrt{\frac{2\frac{m}{M}gR}{(\frac{M}{m} + 1)}}

Part b)

Since on the block wedge system there is no external force in horizontal direction so the Center of mass will not move in horizontal direction but in vertical direction it will move

so displacement in Y direction is given as

y_{cm} = \frac{mR}{m + M}
