Answer: The dissipative component of evolution is in a direction of steepest entropy ascent
Explanation:
According to our definition, every non-equilibrium state of a system or local subsystem for which entropy is well defined must be equipped with a metric in state space with respect to which the irreversible component of its time evolution is in the direction of the steepest entropy ascent permissible under the conservation constraints. We derive (nonlinear) expansions of Onsager reciprocity and fluctuation-dissipation relations to the far-non-equilibrium world inside the rate-controlled constrained-equilibrium approximation to demonstrate the force of the fourth law (also known as the quasi-equilibrium approximation).

a car drives straight off a flat cliff that is 57 m high (its initial velocity is purely horizontal). the point of impact is 130 m from the base of the cliff. how fast was the car traveling when it went over the cliff?
The speed of the car traveling when it went over the cliff is 38.12 m/s.
The equation of motion for calculating the displacement of a moving object is given as
[tex]S = ut + \frac{1}{2} at^{2}[/tex]
u = initial velocity
t = time taken
a = acceleration of the object
S = displacement of the object
The above equation can be used to find out the speed of the car.
In this case, the initial velocity, u, is zero because the car falls under gravity. The acceleration, a, will be considered as acceleration due to gravity (g). The time taken is the 'time of flight' taken as 't' and S is taken as the height (h) of the flat cliff.Therefore, the above equation can be written as
[tex]h = \frac{1}{2} gt^{2}\\t = \sqrt[]{\frac{2h}{g} } \\t = \sqrt[]{\frac{2(57)}{9.8} } \\\\t = 3.41 s[/tex]
Therefore, the time of flight = 3.41 s.
If the point of impact from the base of the cliff is 130 m and the time of flight is 3.41 s.
Then, the velocity of the car traveling over the cliff is calculated as
[tex]v = \frac{point of impact}{t} \\\\v = \frac{130}{3.41} \\\\v = 38.12 m/s[/tex]
The velocity of the car traveling when it went over the cliff is 38.12 m/s.

a ringing alarm clock is put under a glass jar. the air is slowly removed from the space around it. what will happen as the air is removed?
The level of the sound can be decreased by gradually draining the air from a plastic bottle. The sound about an alarm clock cannot be heard at all since sound cannot travel through a vacuum.
What will occur once the air is drained away?A ringing alarm clock will gradually grow quieter when air is gently drawn out of the area around it and placed beneath a glass jar. Because sound is indeed a mechanical wave that moves across a medium, this is the case.
We can hear the sound because the air molecules in the jar shake as sound waves pass through them. The amount of air particles available to vibrate and convey sound waves declines when air is eliminated, which lessens the sound's strength. There will be so little remaining air to vibrate due to the almost full removal of the air that the sound will be almost undetectable.

In accordance with Hooke's law, a principle of elasticity, for relatively minor deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load The elasticity of an object is likewise governed by Hooke's law; for example, a metal spring can only be stretched so far before being broken by too much effort. A mass that we already have is then expanded out by x. Displacement and acceleration are inversely related.

The magnitude of the acceleration is |8.1 * 10^5| m/s^2 = 8.1 * 10^5 m/s^2
What is meant by acceleration?In mechanics, rate of change of velocity of an object with respect to the time is called as acceleration.
As it is known, F = k * (q1 * q2)/r^2
where F is force, k is Coulomb's constant (9 x 10^9 N * m^2/C^2), q1 and q2 are charges of the two spheres, and r is distance between the two spheres.
As we know that , F = m * a
a = F/m
a = (k * (q1 * q2))/r^2) / m
a = (9 * 10^9 N * m^2/C^2 * (-23 * 10^-9 C)^2) / (10^-2 m)^2
Acceleration of the upper sphere is a = -8.1 * 10^5 m/s^2. The negative sign indicates that acceleration is in opposite direction to the force, as expected, since the force is repulsive.

and the force of gravity, mg
T1x = −T1 cos 57.6°
T2x = T2 cos 33.8°
mgx = 0
T1y = T1 sin 57.6°
T2y = T2 sin 33.8°
mgy = −mg
Thus, the x and y components of the resultant force will be:
x:
Rx = T1x + T2x + mgx
Rx = −T1 cos 57.6° + T2 cos 33.8° + 0
Rx = T2 cos 33.8° − T1 cos 57.6° (1)
y:
Ry = T1y + T2y + mgy
Ry = T1 sin57.6°+ T2 sin 33.8° + (−mg)
Ry = T1 sin 57.6° + T2 sin33.8° − mg (2)
The next step is to substitute Rx and Ry in Eq. (1) and Eq. (2) with 0:
Rx = T2 cos 33.8° − T1 cos 57.6°
Ry = T1 sin57.6° + T2 sin 33.8° − mg
↓
0 = T2 cos33.8°− T1 cos 57.6° (3)
0 = T1 sin57.6°+ T2 sin 33.8°− mg (4)
Using these two equations we can easily find T1 and T2.
There are multiple ways in which we can do this. One way would be to first solve Eq. (3) for T2:
0 = T2 cos33.8°− T1 cos 57.6°
T2 cos 33.8° − T1 cos 57.6° = 0
T2 cos 33.8° = T1 cos 57.6°
T2 = T1 cos57.6°/ cos 33.8°
T2 = 0.747T1 (5)
hen, we substitute T2 with 0.735T1 in Eq. (4):
0 = T1 sin 57.6°+ T2 sin 33.8° − mg
0 = T1 sin 57.6° + 0.735T1 sin 33.8°− mg
And we solve it for T1:
0 = T1 (sin 57.6° + 0.747 sin 33.8°) − mg
0 = T1 (0.848) − mg
mg = 0.848T1
0.848T1 = mg
T1 = mg /0.848
T1 = (4.2kg) (9.81 N/kg) / 0.848T
T1 = 48.58 N
Finally, we substitute the value of T1 in Eq. (5) to find T2:
T2 = 0.747T1
T2 = (0.747) (48.58 N)
T2 = 36.28 N
Therefore, the tension in the rope at the 57. 6°angle is 48.58 N, and the tension in the rope at the 33. 8°angle is 36.28 N.

The potential at a point in space due to a point charge is given by the equation:
V = k * Q/r
where V is the potential, k is the Coulomb constant [tex](8.99 x 10^9 N * m^2/C^2)[/tex], Q is the charge, and r is the distance from the point charge to the point where the potential is being calculated.
In this problem, we have two point charges placed 5 cm apart on the x-axis. How about we call the charges Q1 and Q2, and we should assume that Q1 is located at the origin (x = 0) and Q2 is located at x = 5 cm.
The potential at a point along the x-axis is the amount of the potentials due to each of the point charges.
V = k * Q1/r1 + k * Q2/r2
where r1 is the distance from the point to Q1 and r2 is the distance from the point to Q2.
In the event that the potential at a point is zero, the amount of the potential due to each of the point charges is zero.
So, k * Q1/r1 + k * Q2/r2 = 0
To find the points along the x-axis where the potential is zero, we can set the equation above equal to zero and address for x.
r1 = x and r2 = |x - 5 cm|
k * Q1/x + k * Q2/|x - 5 cm| = 0
x = k * Q1/Q2 * |x - 5 cm|
x = k * Q1 * (5 cm - x)/Q2
x = 5 cm * k * Q1/(Q1 + Q2)
In this way, the point where the potential is zero is located at

Describe wavelength?Wavelength is a measure of the distance between consecutive peaks (or troughs) of a wave, such as a sound wave or an electromagnetic wave (like light). It is typically measured in meters (m) or nanometers (nm). The wavelength of a wave determines its color, with shorter wavelengths appearing as blue or violet and longer wavelengths appearing as red. In the case of electromagnetic waves, the wavelength also determines the type of radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
(a) The spacing between successive maxima near the center fringe for light of wavelength 500 nm is given by the formula dsin(θ) = (λ)/d.

an object travels in a circular orbit. if the speed of the object is doubled, its centripetal acceleration will be
If an object is traveling in a circular orbit where its speed is doubled, then its centripetal acceleration will be quadrupled.
Centripetal acceleration is the acceleration of an object traversing a circular path. Because velocity is a vector quantity, i.e., it has both a magnitude ( the speed and a direction), so when the object travels on a circular path, its direction changes constantly and thus as a result of this its velocity changes, producing acceleration,
For instance, when an object in a circular orbit is moved with double doubled, then it has quadrupled centripetal acceleration.

a 3500 pf air-gap capacitor is connected to a 22-v battery. if a piece of mica is placed between the plates, how much charge will flow from the battery?
The amount of charge that will flow from the battery is 77000pC
A capacitor is a device that stores electrical charge. The amount of charge stored in a capacitor is proportional to the voltage applied across it, according to the equation Q = C*V.
where Q is the charge in coulombs, C is the capacitance in farads, and V is the voltage in volts.
In this case, the capacitance of the air-gap capacitor is 3500pF (pico-farads) and the voltage is 22V, so the charge stored in the capacitor is:
Q = 3500pF * 22V = 77000pC (pico-coulombs)
When a piece of mica is placed between the plates, it reduces the space between the plates, which will increase the capacitance of the capacitor. The increase in capacitance will result in an increase in the amount of charge stored in the capacitor.
It's worth noting that the charge that flows from the battery is equal to the initial charge stored in the capacitor. Since the initial charge stored in the capacitor is 77000pC, this is the amount of charge that will flow from the battery.

A positive charge is brought close to a fixed neutral Which of the figures best represents the charge distribution on the inner and outer walls of the conductor that has a cavity. The cavity is neutral; that is, there is no net charge inside the cavity. Which of the figures best represents the change distribution on the inner and outer walls of the conductor?
The correct option: (e) There is a negative charge on the surface of the cavity, and a positive charge on the outer surface of the conductor.
State the Gauss law for the conductor?Any extra charge on the a conductor will be located on its surface, according to Gauss' Law.
According to Gauss' Law, the surface's electric field and internal charge are related. The charge encapsulated by any surface on the inside of a conductor equals zero since there is no electric field there. Any charge here on conductor must therefore be located on its surface. There wouldn't be an electric field inside the conductor's vicinity if a cavity was cut out of it, and there wouldn't be any charge inside the cavity either. Therefore, the hollow wouldn't have an electric field. Because of electric field should be perpendicular to its surface and the conductor's internal electric field is zero, no flux can penetrate the conductor.Thus, on the cavity's surface there is a negative charge, while the conductor's outer surface has a positive charge.
