The answer we get is that  the algorithm checked 12, 20, 24, and 25, which are 4 elements.

how we know that?

To find 25 using binary search, 4 elements will be checked. Binary search works by checking the middle element of a sorted list, then comparing it to the element you're looking for. If the middle element is greater than the element you're looking for, you move on to the left side of the list and repeat the process, and if it is smaller you move to the right side and repeat the process.

In this case, the middle element is 20, which is smaller than 25, so the algorithm will check the right side of the list. The middle element of the right side of the list is 24, which is also smaller than 25, so the algorithm will check the right side of the list again. The middle element of the right side of the list is now 25, which is equal to the element we are looking for.

Answer:

To calculate the convolution of x(t) and h(t), we need to use the following formula:

y(t) = integral from 0 to t of {x(tau) h(t - tau) d(tau)}

First, we need to find x(tau) and h(t - tau):

x(tau) = u(tau - 3) - u(tau - 5)

h(t - tau) = e^(-3(t - tau)) u(t - tau)

Substituting these into the convolution formula, we get:

y(t) = integral from 0 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] u(t - tau) d(tau)}

Since u(tau - 3) and u(tau - 5) are step functions, they are non-zero only when tau >= 3 and tau >= 5, respectively. Therefore, the integral can be broken up into two parts:

y(t) = integral from 3 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] d(tau)}

- integral from 5 to t of {(u(tau - 5)) e^[-3(t - tau)] d(tau)}

Simplifying this, we get:

y(t) = (e^(-3t)) [integral from 3 to t of e^(3tau) d(tau) - integral from 5 to t of e^(3tau) d(tau)]

- e^(-15t) integral from 5 to t of e^(3tau) d(tau)

Evaluating the integrals, we get:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)

Therefore, the convolution of x(t) and h(t) is:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)

The magnitude of normal stress is greatest at point D. Point A in the triangular cross-section of a homogeneous beam subjected to a pure bending moment.

The cross-section of a homogeneous beam of triangular cross-section, the point of the cross-section where the magnitude of normal stress is the greatest is Point C.

Normal stress is a type of stress that occurs in a member when a force is applied perpendicular to the member's cross-section. It is calculated using the formula: σ = F/A

Where,σ = normal stress, F = the applied force, and A = the cross-sectional area of the member.

Now, let us consider the cross-section of the beam in question:

The centroid of the cross-section is at point C. This means that the cross-section is symmetric with respect to the y-axis. When a pure bending moment is applied to the beam, it causes the top of the beam to compress and the bottom of the beam to stretch. This creates a normal stress that is maximum at the top and minimum at the bottom.

Since the cross-section is symmetric, this maximum normal stress will occur at a point equidistant from the top and bottom of the beam. This point is point C. Therefore, the point of the cross-section where the magnitude of normal stress is the greatest is Point C.

The address of the element stored at arr[20][30] in the 2-D array declaration char Arr[100][100] would be 30 + 20 * 100 = 2030.

The declaration of the 2-D array is shown below:

char Arr[100][100]

Here, Arr is a 2-D array consisting of 100 rows and 100 columns. This means that there are a total of 10,000 elements in this array. Each element of this array is of type char. Therefore, each element will occupy a single byte of memory.

The array is byte-addressable. This means that each element of the array is accessible using its byte address. Since each element occupies a single byte of memory, the byte address of an element is the same as its memory address.

To calculate the address of the element stored at arr[20][30], we first need to understand how the elements are stored in the array.

The elements of a 2-D array are stored in row-major order. This means that the elements of the first row are stored first, followed by the elements of the second row, and so on. Within a row, the elements are stored from left to right.Now, to calculate the address of the element stored at arr[20][30], we need to calculate the byte address of this element. Since the array is byte-addressable, we can calculate the byte address of an element by multiplying its row number by the number of columns in the array and adding its column number. This gives us the following formula:

Byte Address of Element = Base Address + (Row Number * Number of Columns + Column Number)

Since the base address of the array is 0, we can simplify this formula to:

Byte Address of Element = Row Number * Number of Columns + Column Number

Using this formula, we can calculate the byte address of the element stored at arr[20][30] as follows:

Byte Address of Element = 20 * 100 + 30 = 2030

Therefore, the address of the element stored at arr[20][30] is 2030.

The limit on the series resistance so the energy remaining after one hour is at least 75 percent of the initial energy is given by: R ≤ 1.4 Ω

Given data is:

Inductor = 10-H

Suppose that we want to store energy in a 10-H inductor.

Determine the limit on the series resistance so the energy remaining after one hour is at least 75 percent of the initial energy.

The expression for the current in an inductor can be given as:

I = V/R (1 - e^(-Rt/L))

Where, I = current in the inductor

V = potential difference in the inductor

R = resistance of the inductor

L = inductance of the inductor

t = time

Now the expression for the energy stored in an inductor is given as:

W = 1/2 LI^2W = 1/2 L(V/R (1 - e^(-Rt/L)))^2W = 1/2 LI^2 (1 - e^(-2Rt/L))Now, for t = 1 hour

Wfinal = 0.75 Winitial

Therefore,0.75 W

initial = 1/2 LI^2 (1 - e^(-2Rt/L))

On substituting the given values, we get:0.75 Winitial = 1/2 * 10 H * (V/R)^2 (1 - e^(-2R * 1 * 3600/10))0.75 = 1/2 * (V/R)^2 (1 - e^(-720R/10))1.5 = (V/R)^2 (1 - e^(-720R/10))1.5 = (V/R)^2 (1 - e^(-72R))1.5 = (V/R)^2 (1 - e^(-9R/2))

Therefore, the limit on the series resistance so the energy remaining after one hour is at least 75 percent of the initial energy is given by:

We have to find the value of Z_L in the given circuit in order for Z to receive maximum average power and the maximum average power received by ZL.

Calculation Average Power delivered to Z_L is given by the formula:

Pavg = Veff² / (R + R_L)

We know that: Veff = I * Z...[tex]Z = R + j(X_L - X_C)[/tex]

Putting the given values in the above formula...

Z = 102 + j(22 - (-30))Z = 102 + j52Z = 58.31 ∠28.78° Ω

We have to find the value of Z_L in the given circuit in order for Z to receive maximum average power. For this, we need to find the value of Z_L which will give maximum power transfer to Z_L. This is possible when the real part of Z_L is equal to the resistance of the circuit (R).

Let Z_L = R_L + jX_L_R_L = R - Z_L

Putting the given values in equation

R_L = 102 - R_L...[tex]2R_L = 102[/tex]R_L = 51 Ω

Now we have the value of R_L. Putting the value of R_L in equation (i) to find the value of X_L.X_L = Z_L - R_X_L = (40.8232 - 22j) Ω

Now we have found the value of Z_L which is 40.8232 - 22j Ω. Maximum average power received by ZL is given by the formula:

Pavg = Veff^2 / (R + R_L)

We have already found the value of R_L. Now we need to find the value of V_eff.V_eff = I * Z...[tex]Z = R + j(X_L - X_C)[/tex]

Putting the given values in the above formula...Z = 102 + j(22 - (-30))Z = 102 + j52Z = 58.31 ∠28.78° ΩI = 9 ∠290° AV_eff = I * ZV_eff = (9 ∠290°) * (58.31 ∠28.78°)

V_eff = 524.1 ∠318.78° V

Putting the values of R, R_L and V_eff in the above formula to find the value of P_avg.

Pavg = Veff² / (R + R_L)P_avg = (524.1)^2 / (102 + 51)P_avg = 1.216 W

The tension in the cable when the balloon is inflated as a sphere having a diameter of 60 ft is equal to T = 2000 - (-29.489) = 2029.489 lb.

The tension in the cable when the balloon is inflated as a sphere having a diameter of 60 ft can be determined by first calculating the volume of the balloon. The volume of a sphere is equal to V = 4/3πr3, where r is the radius of the sphere (or half the diameter). Therefore, the volume of the balloon is V = 4/3π(60/2)3 = 904.778 ft3.

We then need to calculate the lift force generated by the hot air. This is equal to the difference in the weights of the hot air and the ambient air multiplied by the volume of the balloon. The weight of the hot air is equal to the specific weight of hot air (0.040 lb/ft3) multiplied by the volume of the balloon (904.778 ft3). Similarly, the weight of the ambient air is equal to the specific weight of ambient air (0.070 lb/ft3) multiplied by the volume of the balloon (904.778 ft3). Therefore, the lift force is equal to F = (0.040 - 0.070) × 904.778 = -29.489 lb.

Finally, the tension in the cable can be determined by subtracting the lift force generated by the hot air from the total weight of the gondola, weights, passengers, and material. Therefore, the tension in the cable when the balloon is inflated as a sphere having a diameter of 60 ft is equal to T = 2000 - (-29.489) = 2029.489 lb.

                            ΔE_spring = F/k

where F is the force applied to the coupling rod and k is the spring stiffness. Substituting the given values, we have:

                ΔE_spring = 5 kip / 12 kip/in

                             = 0.417 in

Next, we can consider the effect of the bolts. Each bolt will undergo a change in length due to the force applied to the coupling rod. Assuming that the deformation of each bolt is proportional to its length, we can use the following equation to calculate the displacement of point E due to the bolts:

                   ΔE_bolts = (ΔL_AB + ΔL_BC + ΔL_CE) / 3

where ΔL_AB, ΔL_BC, and ΔL_CE are the changes in length of bolts AB, BC, and CE, respectively.

To calculate the changes in length of the bolts, we can use the following formula:

                         ΔL = F L / (AE E)

where L is the length of the bolt, AE is the cross-sectional area of the bolt, and E is the modulus of elasticity of the bolt material. For A-36 steel, the modulus of elasticity is 29,000 ksi.

Using this formula, we can calculate the changes in length of each bolt as follows:

ΔL_AB = (5 kip) (4 in) / ((0.25 in)² π/4 (29,000 ksi))

                           = 0.0025 in

ΔL_BC = (5 kip) (6 in) / ((0.25 in)² π/4 (29,000 ksi))

                             = 0.0037 in

ΔL_CE = (5 kip) (10 in) / ((0.25 in)² π/4 (29,000 ksi))

                               = 0.0061 in

Substituting these values into the equation for ΔE_bolts, we have:

ΔE_bolts = (0.0025 in + 0.0037 in + 0.0061 in) / 3

                           = 0.0041 in

Finally, we can add the displacements due to the spring and bolts to obtain the total displacement of point E:

ΔE_total = ΔE_spring + ΔE_bolts

                              = 0.417 in + 0.0041 in

                                       = 0.421 in

Therefore, the distance between C and E accounting for the compression of the spring and the deformation of the bolts is:

d = 10 in + ΔE_total = 10 in + 0.421 in

                          = 10.421 in

Therefore, the distance between C and E is 10.421 inches when the coupling rod is subjected to a force of 5 kip, accounting for the compression of the spring and the deformation of the bolts.

When testing a four-wheel drive electronic component, the technician will use a scan tool to pull codes, and then a multimeter to diagnose any codes found.

A multimeter is an electronic measuring instrument that combines various measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters have a microammeter whose pointer moves over a scale calibrated for all the various measurements that can be taken; digital instruments display digits on a screen; and, if equipped, an audio output for continuity and an auxiliary transducer input for temperature or capacitance measurement are also available. The multimeter's main purpose is to determine whether the electrical components and circuits are working correctly. To do so, the multimeter uses probes, which are the leads or wires connected to the tool. The black lead is connected to the COM (common) jack on the multimeter, while the red lead is connected to the VΩmA jack. When diagnosing codes found using a scan tool, it is important to use a multimeter to accurately diagnose the cause of the problem.

The CO molecule's initial excited vibrational state has a displacement from the equilibrium bond distance that is most likely 0.2262 Angstroms.

A diatomic molecule vibrates similar to two masses being supported by a spring, and its potential energy is proportional to the square of the deviation from equilibrium. But the quantized energy levels have values that are evenly spaced apart. The frequency in this form corresponds to the simple harmonic oscillator's traditional form.

[tex]x = √(h/2μω)(2(1)+1/2) = √(h/2(1.14x10^-27 kg)(6.505x10^13 Hz))(3/2)[/tex]

[tex]x = 2.262 x 10^-11 meters[/tex]

Force in lbf required to lower the screw = 45.9

Force in lbf required to lower the screw given the R is 7 in long, 1.0 in diameter screw with a pitch p = 0.130 in, where Q is 14 lbf of force and the coefficient of friction is 0.40 can be determined as follows:The pitch is defined as the distance between the same two points on successive threads.

We will make use of the formula given below to find out the force required to lower the screw by using the concept of worm drive.

tan Φ=frictional force/perpendicular force (p/πd)

Φ= inverse tan (frictional force/perpendicular force (p/πd))

Where, Φ is the helix angle of the worm, and d is the diameter of the screw

Substitute the values in the above formula.

tan Φ=0.4 / (0.130/π×1)

Φ = inverse tan (0.4 / (0.130/π×1))

= 19.08 degrees

Tangential force, F = Q/sin Φ

F = 14 / sin 19.08
