To determine the nominal dimensions and acreage of the parcel described as "NW 1/4, NE 1/4, Sec. 28," we need to know the location of the section and the specific units of measurement being used.

However, assuming that the section is located in the United States and follows the Public Land Survey System (PLSS), we can make some general assumptions. The PLSS is a system used to divide and describe land in the United states. Under this system, land is typically divided into 36 sections, each of which is one square mile (640 acres) in size. Each section is then further divided into quarters, with each quarter section consisting of 160 acres. Based on this information, we can assume that the parcel described as "NW 1/4, NE 1/4, Sec. 28" refers to the northwest quarter of the northeast quarter of Section 28. Since each quarter section is 160 acres, the parcel in question would be 40 acres in size (i.e., 1/4 of 1/4 of 640 acres). As for nominal dimensions, without more specific information about the shape of the parcel, it's difficult to provide an exact answer. However, we can assume that the parcel is roughly square or rectangular, with each side measuring approximately 1/4 of a mile (or 1,320 feet).

So, during the 25-second period, the front-loading washing machine makes 250 revolutions, and during the first 12.5 seconds, it makes 187.5 revolutions.

A front-loading washing machine with a spin rate of 1200 rev/min decelerates uniformly to rest in 25 seconds. To determine the number of revolutions made during this period and the first 12.5 seconds, we need to calculate the angular deceleration and then use the equations of motion.

First, let's convert the spin rate from rev/min to rev/s:
1200 rev/min * (1 min/60 s) = 20 rev/s

Now, let's calculate the angular deceleration (α) using the formula vf = vi + αt, where vf = 0 (rest), vi = 20 rev/s (initial spin rate), and t = 25 s (time to stop):
0 = 20 + α(25)
α = -20/25 = -0.8 rev/s²

Next, we can find the total number of revolutions made during the 25-second period using the equation s = vit + 0.5αt²:
s = (20)(25) + 0.5(-0.8)(25²) = 500 - 250 = 250 revolutions

Finally, we can find the number of revolutions made during the first 12.5 seconds using the same equation with t = 12.5 s:
s = (20)(12.5) + 0.5(-0.8)(12.5²) = 250 - 62.5 = 187.5 revolutions.

Answer

The cost function, C(q), as a function of output q. The contingent factor demands are the optimal quantities of k and l that minimize the cost function given the production function and factor prices y and w.

Explanation

Given the production function q = f(k, l) = 8k^(3/4)l^(1/4), factor prices y and w, the producer's cost minimization problem can be written as:

Minimize C = yk + wl

Subject to the constraint:

q = 8k^(3/4)l^(1/4)

To find the contingent factor demands, we can use the Lagrangian method, setting up the Lagrangian function:

L(k, l, λ) = yk + wl + λ(q - 8k^(3/4)l^(1/4))

Take partial derivatives with respect to k, l, and λ, and set them equal to zero:

∂L/∂k = y - (3/4)λ8k^(-1/4)l^(1/4) = 0
∂L/∂l = w - (1/4)λ8k^(3/4)l^(-3/4) = 0
∂L/∂λ = q - 8k^(3/4)l^(1/4) = 0

Solve this system of equations to find k, l, and λ. Substitute the expressions for k and l in terms of λ back into the cost function:

C = yk(λ) + wl(λ)

This will give you the cost function, C(q), as a function of output q. The contingent factor demands are the optimal quantities of k and l that minimize the cost function given the production function and factor prices y and w.

Given an array A[1..n] representing a sequence of n integers, we can define LMS(i) as the length of the longest monotonically increasing subsequence of A[1..i] that ends with A[i]. We can write a recurrence relation for LMS(i) as follows:
LMS(i) = 1 if i = 1,
LMS(i) = 1 + max{LMS(j)} if A[i] > A[j] for all j = 1, 2, ..., i - 1,

Ro will change by 4 times If in an NMOS transistor, both W and L are quadrupled

a) To find VA and λ, we can use the following equations:

VA = 1/′ = 1/(400 μA/V2) = 2.5 V

λ = ′/L = 5 V/μm / 0.54 μm = 9.26 V-1

To find the value of iD at an overdrive voltage of 0.25 V and vDS = 1 V, we can use the following equation for the saturation current:

iD = (1/2)′(W/L)(VOV)2 = (1/2)(400 μA/V2)(5.4 μm / 0.54 μm)(0.25 V)2 = 2.25 mA

To find the output resistance (ro) at this operating point, we can use the following equation:

ro = (V_A / i_D) + (1/λ) = (2.5 V / 2.25 mA) + (1/9.26 V-1) = 1.11 kΩ

If vDS is increased by 0.5 V, we need to recalculate iD using the same equation as before, but with VOV = 0.25 V + 0.5 V = 0.75 V:

iD' = (1/2)(400 μA/V2)(5.4 μm / 0.54 μm)(0.75 V)2 = 8.1 mA

The change in iD is therefore:

The linear range of υs for rl = 4 k will be determined by the maximum current that can flow through rl without causing it to saturate or go into non-linear operation.

To determine the gain of the circuit, we need to find the ratio of the output voltage (υl) to the input voltage (υs). From the circuit diagram, we can see that the output voltage is taken across the resistor rl, while the input voltage is applied across the resistor r1.

Using Kirchhoff's laws, we can write the following equation for the circuit:

υs = υin - i1*r1

where i1 is the current flowing through resistor r1. We can solve for i1 using Ohm's law:

i1 = υin/r1

Substituting this expression for i1 in the first equation, we get:

υs = υin - υin/r1 * r1

Simplifying, we get:

υs = υin(1 - 1) = 0

This means that the input voltage does not affect the output voltage, and the gain of the circuit is zero.

As for the linear range of υs, we can see from the circuit diagram that the voltage across rl will be proportional to the current flowing through it, which is given by:

il = υs/rl

This will depend on the power rating of rl and the maximum voltage that can be applied across it.

Without more information about the specific components used in the circuit, it is not possible to determine the exact linear range of υs.

However, in general, the linear range of a circuit refers to the range of input voltages for which the output voltage is proportional to the input voltage, and the circuit operates in a linear manner.

This range will depend on the characteristics of the components used in the circuit, such as their voltage and current ratings, and their frequency response.

The conductors of a single phase are not permitted to be run in metallic conduit because eddy currents will be induced.

When conductors are run in metallic conduits, eddy currents are induced due to the changing magnetic field around the conductor. These eddy currents can result in overheating of the conductors and can also cause power losses. In single-phase systems, the current in the two conductors is out of phase by 180 degrees, resulting in a constantly changing magnetic field.

Thus, running the conductors in metallic conduit can lead to induced eddy currents that can cause damage to the system. To prevent this, non-metallic conduits are used for single-phase systems, as they do not induce eddy currents.

The total voltage (Vt) in the circuit is 56V.

To calculate the total voltage (Vt) in a series circuit, we need to first calculate the total resistance (Rt) using Ohm's Law:

Rt = R1 + R2 + R3

Rt = 10 kohms + 10 kohms + 15 kohms = 35 kohms

Next, we can use Ohm's Law again to calculate the total current (It) in the circuit:

It = Vt / Rt

We have one known voltage drop across resistor R1 (Vr1 = 16V), so we can calculate the current flowing through R1 using Ohm's Law:

Vr1 = R1 * Ir1

Ir1 = Vr1 / R1 = 16V / 10 kohms = 1.6 mA

Since the circuit is in series, the current flowing through R1 is the same as the total current in the circuit (It). Therefore:

It = Ir1 = 1.6 mA

Now we can use the total current (It) and the total resistance (Rt) to calculate the total voltage (Vt):

Vt = It * Rt = (1.6 mA) * (35 kohms) = 56V

Therefore, the total voltage (Vt) in the circuit is 56V.

A mass-spring-damper system is a type of physical system that involves a mass attached to a spring and a damper (or shock absorber) that provides resistance to motion. In the given equation, x'' represents the acceleration of the mass, x' represents the velocity of the mass, and x represents the displacement of the mass from its equilibrium position.
To determine the damping constant c required to limit the maximum steady-state amplitude of x to 3, we can use the formula for the amplitude of the steady-state response:
A = f0/√((k-mω^2)^2 + (cω)^2)
Where A is the amplitude of the steady-state response, f0 is the amplitude of the input, k is the spring constant, m is the mass, ω is the frequency of the input, and c is the damping constant.
Setting A to 3 and f0 to 11, and solving for c, we get:
