In Fig, the value of P1 is 24 Watts. We have to determine how much power is absorbed by element 2. The potential difference across element 1 is 9 Volts, and the potential difference across element 2 is 5 Volts.

From Ohm's law, the relation between power (P), voltage (V), and resistance (R) can be given as:

P = V²/R

Assuming R1 as the resistance of element 1, and R2 as the resistance of element 2, then the current flowing through R1 can be calculated using the below relation:

I = V1 / R1The current flowing through R2 can be calculated using the below relation:

I = V2 / R2

Since the total current flowing in the circuit is constant and it can be given as: I = P1 / V1Thus, the current flowing through R1 is:

I = V1 / R1 = P1 / V1

And, the current flowing through R2 is:

I = V2 / R2 = P2 / V2Thus, from the above two equations, we can say that:

P1 / V1 = P2 / V2Now, substituting the given values, we get:P2 = (V2 / V1) × P1Therefore, the power absorbed by element 2 can be given as:

P2 = (5 / 9) × 24P2 = 40/3 Watts (approximately 13.33 Watts)

Therefore, the power absorbed by element 2 is approximately 13.33 Watts.

The  rate of change of the current in the solenoid is:

(dI/dt) = emf / R = (-1.81 × 10^-5 V) / R

The emf induced in the wire loop is given by the equation:

emf = -N * (dΦ/dt)

where N is the number of turns in the loop, Φ is the magnetic flux through the loop, and t is the time.

The magnetic flux through the loop can be calculated using the equation:

Φ = B * A

where B is the magnetic field inside the solenoid, and A is the area of the loop.

Since the wire loop is parallel with the coils of the solenoid, the magnetic field inside the solenoid is uniform and given by the equation:

B = μ0 * n * I

where μ0 is the permeability of free space, n is the number of turns per unit length of the solenoid, and I is the current in the solenoid.

Substituting the values given in the problem, we have:

B = (4π × 10^-7 T·m/A) * (965 turns/m) * I = 3.68 × 10^-3 I T

A = π * (0.05 m)^2 = 7.85 × 10^-3 m^2

Φ = B * A = 2.89 × 10^-5 I Wb

Substituting the given values of emf and Φ, we have:

-1.80 × 10^-5 V/m = -965 * (dΦ/dt)

Solving for dΦ/dt, we get:

dΦ/dt = 1.87 × 10^-8 Wb/s

Finally, substituting the value of dΦ/dt in the equation for emf, we get:

emf = -N * (dΦ/dt) = -965 * (1.87 × 10^-8 Wb/s) = -1.81 × 10^-5 V

Therefore, the rate of change of the current in the solenoid is:

(dI/dt) = emf / R = (-1.81 × 10^-5 V) / R

where R is the resistance of the wire loop. The resistance is not given in the problem, so a numerical answer cannot be provided.

2) Average Mass of Grade A Egg       →    56.7 g = 0.056 kg

3) Calculated Mass

Drop Chamber + Egg → (35 + 56.7) g = 91.7 g = 91.7 g × 1 kg/(1000 g) = 0.0917 kg

4) Time of Drop → 1.5 seconds

5) Maximum Velocity of Drop Chamber (v = g·t) → v = 9.8 m/s² × 1.5 s = 14.7 m/s

6) Maximum Momentum of Drop Chamber

(P = m·v) (right before hitting the ground) → p = 0.0917 kg × 14.7 m/s = 1.34799 kg·m/s

7) Final End Momentum of Drop Chamber → After landing, velocity v = 0 m/s

(p = m·v after landing)   \({}\)                              ∴ p = m·v = m × 0 m/s = 0 kg·m/s

Shocks cause shifts in AD and AS curves, and the placement of point E, representing the new equilibrium, depends on these shifts.

Shocks can affect the economy through changes in aggregate demand or aggregate supply. An increase in aggregate demand would shift the AD curve to the right, reflecting higher overall demand for goods and services. This shift would result in a higher level of output and prices in the short run. Consequently, point E would be placed at a higher level of output and higher price level.

On the other hand, a positive supply shock, such as a decrease in production costs or an increase in productivity, would shift the AS curve to the right. This shift implies higher output and lower prices in the short run. In this case, point E would be located at a higher level of output and a lower price level.

Conversely, a negative supply shock, such as an increase in production costs or a decrease in productivity, would shift the AS curve to the left. The resulting equilibrium at point E would be characterized by lower output and higher prices in the short run.

To determine the placement of point E, it is necessary to identify the specific shifts caused by the shocks, such as an AD shift, a positive supply shock (AS shift to the right), or a negative supply shock (AS shift to the left). Once the shifts are identified, the corresponding changes in output and price level can be determined, and point E can be placed accordingly in the new short-run equilibrium.

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).

The displacement of the train to the west is 478 km.

To find the displacement to the west, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the straight-line distance from the starting point to the ending point) is equal to the sum of the squares of the lengths of the other two sides.

Let's call the displacement to the west "x". Then, the displacement to the south is 42 km, and the total displacement (the distance traveled by the train) is 478 km. Using the Pythagorean theorem, we can write the following equation:

x^2 + 42^2 = 478^2

Expanding the squares:

x^2 + 42^2 = 478^2

x^2 + 1764 = 229284

The statement "When a permanent magnet is cut in half, one piece will be a north pole and one piece will be a south pole" is False.

When a permanent magnet is cut in half, it does not result in separating the magnet into distinct north and south poles. Instead, each resulting piece will still have its own north and south poles. This phenomenon is known as magnetic domain alignment. The domains within a magnet are regions where the magnetic moments of atoms align in the same direction, creating a magnetic field. Cutting a magnet disrupts the alignment of these domains, but it doesn't create isolated north and south poles on separate pieces.

Regardless of how a permanent magnet is divided, each resulting piece will have its own north and south poles. The magnetic field lines will still flow from the north pole to the south pole within each piece. Therefore, the statement "When a permanent magnet is cut in half, one piece will be a north pole and one piece will be a south pole" is false.

At x = 0, there are no dislocated impulses, while at x = 3, there are 13,200 dislocated impulses.

The problem states that the number of dislocated electric impulses per cubic inch in a transformer increases when lightning strikes by D = 1100(4)×,

where × represents the time in milliseconds of the lightning strike.

We need to find the number of dislocated impulses at x = 0 and x = 3.

To find the number of dislocated impulses at x = 0, substitute x = 0 into the equation D = 1100(4)×:

D(0) = 1100(4)(0)

D(0) = 0

So, at x = 0, there are no dislocated impulses.

To find the number of dislocated impulses at x = 3, substitute x = 3 into the equation:

Since light takes around 230 years to travel the distance from the star to us, the light we see tonight departed that star 230 years ago.
