Answer:

W18 * 106

Explanation:

Given that the section modulus of the wide flange beam is 200 in^3 the lightest beam possible that can satisfy the section modulus must have a section modulus ≥ 200 in^3. also the value of the section modulus must be approximately closest to 200in^3

From wide flange Beam table ( showing the section modulus )

The beam that can satisfy the condition is W18 × 106  because its section modulus ( s ) = 204 in^3

Answer:

As the impurity concentration in solid solution is increased, the tensile and yield strengths increases.

Explanation:

The addition of impurities in solid solutions shows an improved tensile and yield strength due to the grain refinement and obstacles to the motion of dislocation.

Example, the addition of carbon as impurity into iron, which forms steel shows a significant increase in the tensile and yield strengths of iron.

Blacksmiths also use work hardening to introduce dislocation into solid solutions in order to increase their  tensile and yield strengths.

Therefore, as the impurity concentration in solid solution is increased, the tensile and yield strengths increases.

A solid solution is a mixture of crystalline solids and is soluble over the partial or evenly complete range.

Hence the option Increases is correct.

The velocity of the ball just after the impact with the wall is 15 m/s.

To determine the velocity of the ball just after the impact with the wall, we can use the equation of the coefficient of restitution:

e = (Vb2 - Vw2) / (Vb1 - Vw1)

Where:

e is the coefficient of restitution (given as 0.75)

Vb1 is the initial velocity of the ball before impact (given as 20 m/s)

Vb2 is the final velocity of the ball after impact (unknown)

Vw1 is the initial velocity of the wall (assumed to be 0 m/s)

Vw2 is the final velocity of the wall (assumed to be 0 m/s, as it is a smooth wall)

Substituting the given values into the equation, we can solve for Vb2:

0.75 = (Vb2 - 0) / (20 - 0)

0.75 * 20 = Vb2

Answer:the inflating Ballon expirement

Explanation:

Answer:

a) 4160 V

b) 12 kW and 81 kVAR

c)  54 kW and 477 kVAR

Explanation:

1) The phase voltage is given as:

\(V_p=\frac{3810.5}{\sqrt{3} }=2200 V\)

The complex power S is given as:

\(S=560.1(0.707 +j0.707)+132=660\angle 36.87^o \ KVA\)

\(where\ S^*\ is \ the \ conjugate\ of \ S\\Therefore\ S^*=660\angle -36.87^oKVA\)

The line current I is given as:

\(I=\frac{S^*}{3V}=\frac{660000\angle -36.87}{3(2200)} =100\angle -36.87^o\ A\)

The phase voltage at the sending end is:

\(V_s=2200\angle 0+100\angle -36.87(0.4+j2.7)=2401.7\angle 4.58^oV\)

The magnitude of the line voltage at the source end of the line (\(V_{sL}=\sqrt{3} |V_s|=\sqrt{3} *2401.7=4160V\)

b) The Total real and reactive power loss in the line is:

\(S_l=3|I|^2(R+jX)=3|100|^2(0.4+j2.7)=12000+j81000\)

The real power loss is 12000 W = 12 kW

The reactive power loss is 81000 kVAR = 81 kVAR

c) The sending power is:

\(S_s=3V_sI^*=3(2401.7\angle 4.58)(100\angle 36.87)=54000+j477000\)

The Real power delivered by the supply = 54000 W = 54 kW

The Reactive power delivered by the supply = 477000 VAR = 477 kVAR

Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing.

The values of h at the two internal boundaries are :

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

  i₁ = 0.615

  i₂ =  0.123

  i₃ = 0.0615

Pressure at point 1 ( i.e. pressure between first two formations )

h₁ = h top - i₁L₁

   = 120 - 0.615 * 25

   = 104.625 m

Pressure at point 2 ( i.e. pressure between the 2nd and 3rd formation )

h₂ = h₁ - i₂L₂

    = 104.625 - 0.123 * 25

    = 101.55 m

Therefore we can conclude that The values of h at the two internal boundaries are :  h₁ = 104.625 m , h₂ = 101.55 m

Explanation:

I won't answer each of these, but will give you an explaination of how to solve for each.

You'll need to use Ohm's Law and Kirchhoff's Voltage Law.

Remember Ohm's Law as \(V = IR\).

Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.

\(E_T = E_1 + E_2 + E_3\)

A couple of other helpful notes:

These three resistors are in series which means that the current flowing through them is equal.

So it is easy to see that... \(V = IR \rightarrow E_1 = 4*2 = 8 V\)

Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).

Explanation:

Answer:

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F

Explanation:

Given the data in the question;

Vs = 10∠30°V   { peak value }

V"s\(_{rms\) = 10/√2 ∠30° V

resonance freq w₀ = 10³ rad/s

Average Power at resonance Power\(_{avg\)  = 2.5 W

Q = 5

values of R, L, and C = ?

We know that;

Power\(_{avg\) = |V"s\(_{rms\)|² / R

{ resonance circuit is purely resistive }

we substitute

2.5 = (10/√2)² × 1/R

2.5 = 50 × 1/R

R = 50 / 2.5

R = 20Ω

We also know that;

Q = w₀L / R

we substitute

5 = ( 10³ × L ) / 20

5 × 20 = 10³ × L

100 = 10³ × L

L = 100 / 10³

L = 0.1 H

Also;

w₀ = 1 / √LC

square both side

w₀² = 1 / LC

w₀²LC = 1

C = 1 / w₀²L

we substitute

C = 1 / [ (10³)² × 0.1 ]

C = 1 / [ 1000000 × 0.1 ]

C = 1 / [ 100000 ]

C = 0.00001 ≈ 1 × 10⁻⁵ F

Therefore;

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F

A distance of at least 6 inches should separate the siding from a roof surface.

This is to prevent moisture and water damage that can result from contact between the two surfaces.

When siding is installed too close to the roof surface, rainwater and other moisture can easily seep into the siding and cause rot, decay, and other forms of damage.

This can result in expensive repairs and replacements over time. To avoid this, it is essential to maintain a sufficient gap between the siding and the roof surface.

In addition, proper installation techniques and materials should be used to ensure that the siding is securely attached and able to withstand exposure to the elements over time.

Both the copy constructor and the assignment operator should make deep copies of the object being copied or assigned.

The copy constructor and assignment operator are important concepts in object-oriented programming, particularly in languages like C++. They are responsible for creating copies of objects, either when initializing a new object with the same values as an existing object (copy constructor) or when assigning one object to another (assignment operator).

When creating a copy of an object, it is essential to consider whether a shallow copy or a deep copy should be made. A shallow copy simply copies the memory addresses of the object's data members, resulting in multiple objects pointing to the same data. In contrast, a deep copy creates a new copy of the object's data, ensuring that each object has its own independent set of data.

A 176.19 kW heater would be required to heat the water in the pool from 70 degrees F to 72 degrees F in 1 hour, assuming the heater is 100% efficient.

To calculate the size of the heater required to heat the water in the pool, we need to use the following formula:

Q = m x c x ΔT

where

Q is the amount of heat required,

m is the mass of the water being heated,

c is the specific heat of water, and

ΔT is the change in temperature.

First, we need to calculate the mass of the water in the pool.

One gallon of water weighs 3.79 kg hence 20 000 gallons will be 75 800 kg

Q = m x c x ΔT

Q = 75,800 kg x 4.184 J/g°C x (72°F - 70°F)

Q = 75,800 kg x 4.184 J/g°C x 2°F

Q = 634,294.4 joules

Now, we need to calculate the power of the heater required to deliver this amount of heat in 1 hour (3600 seconds):

Power = Q / t

Power = 634,294.4 joules / 3600 seconds

Power = 176.19 kW
