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 build the memory chip, a number of memory cells are organized in the shape of a matrix. Each row of cells represents a memory word, and all cells in a row are connected to a common line known as the word line.

The word line is driven by an address decoder. It signifies that the RAM is organized in a 64K Words wide format. The x8 indicates that each word is 8 bits long. Most computer literature expresses the size of the processor's memory in multiples of 210 (= 1024), which is abbreviated K. As a result, 65,536 memory locations are written as 64K, implying that the addressing range is 64K. We will need 8 columns and 4 rows of 16K x 1 memory chips in order to simulate 64K x 8 with 16K x 1. There is a control input CS on each chip. It is possible for that chip to take that data input or to send the data to its output line when this input is set to 1. The upper order 2 bits of the 16-bit wide address bus are decoded to provide the four chip select (CS) control signal.

Using Buckingham's pi theorem, here is the prove that CD = f (Fr).

D = f(p∞, V∞, c, g)          equation 1

eD = D/q∞e²                  equation 2

Fr = V/√gc                     equation 3

Equation 1 can be expressed as  f(p∞, V∞, c, g) = 0

Number of physical parameters(n) = 5

Number of fundamental dimensions(k) = 3

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

We reached that,

f(π1, π2) = f(c × g/V∞2 , D/p∞ × V∞ × c ) = 0

To move a piston (or several pistons) back and forth, steam engines require hot steam produced by boiling water. Then a machine or wheel was powered by the piston's action.

The energy source for many machines and vehicles was steam power, which made it less expensive and simpler to create goods in huge quantities. As a result, there was a surge in the need for raw resources to make more machinery that could manufacture more goods. Thomas Savery introduced steam power to industry in 1698. He built and patent the first engine in London, which he named the "Miner's Friend" since it was designed to pump water from mines. Pressure was generated at high temperatures using steam power. This meant that the only energy source that was dependable and affordable enough to build equipment itself was steam power.

To  achieve a tension of 84 N in a 1.36 mm diameter string, it would require approximately 6,250 turns.

The number of turns required to achieve a tension in a string can be calculated using the formula:

T = k * d * N

where T is the tension in the string, k is the spring constant, d is the diameter of the string, and N is the number of turns.

To calculate k, we can use the formula:

k = G * A / L

where G is the modulus of elasticity of the material, A is the cross-sectional area of the string, and L is the length of the string.

Let's assume the modulus of elasticity for the material is 80 GPa and the length of the string is 1 m. Then, the cross-sectional area can be calculated as:

A = (pi/4) * d^2

Using the above formulas, we can calculate the spring constant:

k = 80 * (pi/4) * (1.36e-3)^2 / 1 = 0.68 N/turn

Finally, to find the number of turns required to achieve a tension of 84 N, we can use the formula:

The force required to move a fluid is proportional to the shear stress on the surface of the plate. The shear stress is defined as the force per unit area acting perpendicular to the surface. For a Newtonian fluid, the shear stress is proportional to the velocity gradient.

In this problem, the velocity profile is given as u = (6y - 0.4y^2) mm/s, where y is the height from the plate. The velocity gradient can be calculated as du/dy = 6 - 0.8y mm/s^2. The shear stress is then given by τ = μ * du/dy, where μ is the dynamic viscosity.

The total force required to move the fluid is given by the product of the shear stress and the surface area of the plate. Since the surface area of the plate is 20,000 mm^2, the force P can be calculated as P = 20,000 * μ * (du/dy). Integrating the velocity gradient over the entire height of the fluid, we get the total force required to move the fluid as:

P = 20,000 * μ * (6y - 0.4y^2)

By substituting the values given in the problem, we get:

P = 20,000 * 0.482 * (6y - 0.4y^2) N

The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a rightward shear force. These loads can be calculated based on the structural analysis of the frame and the external loads applied to the frame.

For the second case, N = 355 lb, V = 75.0 lb, M = -727 lb.ft, the bending moment is negative, which indicates that the section is subjected to a clockwise bending moment. The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a leftward shear force.
