As described in Section 2.2.3, a vector in a two-dimensional space can be represented by a complex number, and vector rotation can be accomplished by complex number multiplication. The vector X, in Problem 13 can be represented as X1 =1+j13 = 2160 on a complex plane. We can rotate the vector clockwise by 90° to obtain the vector X, =V3 - j = 28-330. Find the complex number X, so that the new vector X, is the product of X, and X, , i.e., X, = X,X,. Comment on the relationship between the complex number multiplication approach and the rotation matrix approach in Problem 13.

Therefore, the difference between the average daily minimum and maximum temperatures is 26.55°C.

First, multiply the device's heat output by the thermal resistance from the junction to the case to determine the temperature rise between the two. This will give you your maximum case temperature.

Once you get the maximum case temperature, subtract this temperature rise from the highest junction temperature.

Considering that,Syracuse experiences an average daily high temperature of 21.85°C and a daily low temperature of -4.7°C.

26.55 °C is the difference between the two temperatures above, or 21.85 - (-4.7).

Therefore, the difference between the average daily minimum and maximum temperatures is 26.55°C.

For every 1 ft3 of fill volume, 1.14 ft3 of borrow soil is required.

To find the minimum volume of borrow soil required per 1 ft3 of fill volume, we need to find the wet density of the soil and compare it to the maximum dry density.

First, calculate the wet unit weight of the soil using the following formula:

wet unit weight = (dry unit weight x (1 + moisture content)) / (1 + void ratio x moisture content)

where,

dry unit weight = dry density / 62.4 (as dry density is in pcf and unit weight is in pcf)

Using the provided information:

Dry density = 124 pcf

Moisture content = 12%

Void ratio = 0.60

Solid specific gravity = 2.65

We can calculate the dry unit weight:

dry unit weight = 124 / 62.4 = 1.98

And the wet unit weight:

wet unit weight = (1.98 x (1 + 0.12)) / (1 + 0.60 x 0.12) = 2.25

And the wet density:

wet density = wet unit weight x 62.4 = 2.25 x 62.4 = 141.4 pcf

The minimum volume of borrow soil required per 1 ft3 of fill volume is 141.4/124 = 1.14.

Answer:

We know that the total weight of the cakes is 12 cakes * 1.5 kg/cake = 18 kg

We also know that the piece given to boys is 20 g and that given to girls is 30 g.

Let's assume that the number of boys in the school is x.

The number of girls in the school is 2x because it is twice the number of boys.

The total weight of cake given to boys is x * 20 g = 20x g

The total weight of cake given to girls is 2x * 30 g = 60x g

The total weight of cake given to both boys and girls is 20x g + 60x g = 80x g

We can now set up the following equation: 80x g = 18 kg * 1000 g/kg

Solving for x, we get x = (18000/80) = 225

This means there are 225 boys in the school.

The number of girls in the school is 2x = 2 * 225 = 450

Therefore, the total number of children in the school is 450 girls + 225 boys = 675

To find the full load speed of the motor, we can use the following formula:

Full load speed = (No load speed x (1 - (Armature current / Full load current) x (Armature resistance / (Total resistance - Armature resistance))))

Where:

Given that armature resistance is 0.20 Ohm, and the armature reaction weakens the field by 40% on full load, the field resistance is:

Field resistance = armature resistance x (1 + (40/100)) = 0.2 x 1.4 = 0.28 Ohm

Therefore, the total resistance is:

Total resistance = armature resistance + field resistance = 0.20 + 0.28 = 0.48 Ohm

No load speed of the motor is given as N0.

Now, we can plug in the values into the formula and get:

Full load speed = (N0 x (1 - (122 / 122 + 7) x (0.20 / (0.48 - 0.20))))

Given that the contact drop/brush is 1V and is neglected in the calculation.

We can now calculate the full load speed of the motor, which is the final answer.

In order to write the solution set of a homogeneous system of linear equations in parametric vector form, we can use the method of Gaussian elimination.

Gauss-Jordan elimination to find the reduced row-echelon form of the matrix representing the system. For example, in Exercise 5, we can write the augmented matrix of the system as follows:

[  1   3    1  0]

−4 −9   2 0

[0  −3 −6 0]

Applying Gaussian elimination, we can use row operations to transform the matrix into reduced row-echelon form:

[1  0  −2   0]

0  1    3    0

[0  0   0   0]

From this form, we can see that the system has an infinite number of solutions, represented by the parameterized vector. So the solution set can be written in parametric vector.

In Exercise 6, we can write the augmented matrix of the system as follows:

Applying Gaussian elimination, we can use row operations to transform the matrix into reduced row-echelon form. From this form, we can see that the system has a unique solution, represented by the vector:

According to Buckingham π theorem, this equation can be a function of (n-k = 2) dimensionless period (π1 and π2)

Let

π1 = f(p∞, V∞, c, g)

π2 = f(p∞, V∞, c, D)

We can further express the π1 terms as follows:

π1 = p∞ a1 × V∞b1 × [tex]c^{c}[/tex] × g

Substituting units:

π1 = [[tex]ML^{-3}[/tex]]a1 × [[tex]LT^{-1}[/tex]]b1 × [L]c × g

a1 = 0,

b1 + c1 + 1 = 0,

-b1 - 2 = 0

a1 = 0, b1 = -2, c1 = 1

So,

π1  = V∞ -2 × c × g

Now,

We can further express the π2 terms as follows:

π2 = p∞ a1 × V∞b1 × [tex]c^{c}[/tex] × g

Substituting units:

π2 = [[tex]ML^{-3}[/tex]]a1 × [[tex]LT^{-1}[/tex]]b1 × [L]c × g

a2 + 1 = 0,

-b2 - 2 = 0,

-3a2 + b2 + c2 + 1 = 0

a2 = -1, b2 = -2, c2 = -2

So,

π1  =D/ p∞ × V∞ × c
