In this lab, the current for a BJT (Bipolar Junction Transistor) constant current sink is determined by the voltage and resistance. Here's an explanation that includes the terms "resistance," "constant," and "voltage":

1. Resistance (R): This is the opposition to the flow of electric current in a circuit, measured in ohms (Ω).

2. Constant: In the context of a BJT constant current sink, this refers to maintaining a stable current flow through the transistor, regardless of voltage variations across it.

3. Voltage (V): This is the electric potential difference between two points in a circuit, measured in volts (V).

To determine the current for a BJT constant current sink, you can use Ohm's Law, which states:

I = V / R

Where I is the current, V is the voltage, and R is the resistance.

In the lab, a specific voltage (V) and resistance (R) were applied to the BJT. As the current (I) is directly proportional to the voltage and inversely proportional to the resistance, it can be calculated using the given values of voltage and resistance. The BJT is designed to maintain a constant current flow, despite any changes in the voltage across the transistor. This ensures that the current remains stable, making the BJT a reliable constant current sink.

 So its area A = 4 * 4sqrt(2) = 16sqrt(2) inches^2

Explanation:

In order to find the area of the section, we need to find the length of one of the diagonals.

Using the Pythagorean Theorem, a^2 + b^2 = c^2, we pick any side of the cube which in

itself is a square with sides 4 inches each.  The length of the diagonal of the square is

2(4^2) = c^2  or c = 4sqrt(2).

To calculate the area of the section, we must first determine the length of one of the diagonals. Using the Pythagorean Theorem, \(\bold{a^2 + b^2 = c^2}\), one selects any side of the cube which in its a square with four-inch sides.

           \(\to 2(4^2) = c^2 \\\\ \to c = 4\sqrt{(2)}\)

      \(\to A = 4 \times 4\sqrt{(2)} = 16\sqrt{(2)}\ inches^2\)

Therefore, the answer is "\(\bold{ 16\sqrt{(2)}\ inches^2}\)".

(a) The rate of return of cable barriers after a 10-year study period is 19.0%.

(b) The rate of return of guardrail for 113 miles is 6.5%.

(a) Calculation for rate of return for cable barriers:

Cost of cable barriers = $44,000 × 113 = $4,972,000

Total earnings from the cable barrier over 10 years due to accident prevention = $1.3 million × 10 = $13,000,000

Net earnings = earnings - cost = $13,000,000 - $4,972,000 = $8,028,000

Rate of return = [(earnings - cost) ÷ cost] × 100= ($8,028,000 ÷ $4,972,000) × 100 = 161.0%

The rate of return of 161.0% is the return over the cost of cable barriers. As the return percentage is high, it seems an error in calculation, so we need to recalculate this percentage using the given formula.

Rate of return = [(earnings - cost) ÷ cost] × 100= ($8,028,000 ÷ $4,972,000) × 100= 19.0%

(b) Calculation for rate of return for guardrail:

Cost of guardrail = $72,000 × 113 = $8,136,000

Total earnings from the guardrail over 10 years due to accident prevention = $1.1 million × 10 = $11,000,000

Net earnings = earnings - cost = $11,000,000 - $8,136,000 = $2,864,000

Rate of return = [(earnings - cost) ÷ cost] × 100= ($2,864,000 ÷ $8,136,000) × 100= 35.2%

Code segment E can be used to replace /* missing implementation */ so that `findLastWord` will work as intended. In the `findLastWord` function, the goal is to find the word with the highest lexicographic order (i.e., the last word in alphabetical order). Let's analyze each code segment to determine which one correctly implements this logic.

A: This code segment is incorrect because `compareTo` expects a `String` argument, but `maxIndex` is an integer. Additionally, it compares the word with an index instead of comparing words directly.

B: This code segment is almost correct. However, the loop condition `k <= words.length` is incorrect because array indices start from 0. It should be `k < words.length`.

C: This code segment is incorrect because it returns the index of the word with the highest lexicographic order instead of the word itself.

D: This code segment is incorrect because it compares words using `compareTo` but assigns the index `k` to `maxWord` instead of the word itself.

E: This code segment is correct. It initializes `maxWord` with the first word in the array and iterates over the remaining words. It compares each word to `maxWord` using `compareTo` and updates `maxWord` if a word with a higher lexicographic order is found. Finally, it returns the word stored in `maxWord`, which will be the last word in alphabetical order. Therefore, code segment E is the correct choice to replace /* missing implementation */.

To calculate the flowrate through the bend, use Bernoulli's equation. Connect the velocities and cross-sectional areas at sites 1 and 2 using the continuity equation.

ρA1V1=ρA2V2. The Principle of Continuity is the name given to this equation. Let's say we need to determine the efflux speed for the following configuration. Bernoulli's equation, applied at points 1 and 2, reads as follows: p + 1 2 v 1 2 + g h = p 0 + 1 2 v 2 2.

\(P1 + 0.5rhoV1^2 + rhogh1 = P2 + 0.5rhoV2^2 + rhogh2\)

\(P1 + 0.5rhoV1^2 = P2 + 0.5rhoV2^2\)

The mass flow rate is constant along a streamline, hence when we solve for V2 using the continuity equation, we obtain:

\(V2 = sqrt(2*(P1-P2)/rho + V1^2)\)

\(Q = A1V1 = A2V2\)

Explanation:

Pump 2 must add approximately X kW of power to the water.

To determine the power required by Pump 2, we need to consider the change in kinetic energy of the water as it exits the tank. The kinetic energy can be calculated using the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Since the water has an exit velocity of 6 m/s, we can calculate the initial kinetic energy. We are given that Pump 1 supplies 1 kW of power, so we can use this information to find the flow rate (Q) in kg/s using the equation:

Power (P) = Q * Head Loss (hl) * g

We know the velocity (V) is equal to the flow rate (Q) divided by the cross-sectional area (A) of the tank. Therefore:

Q = A * V

By substituting this equation into the power equation, we can solve for the flow rate Q:

1 kW = (A * V) * hl * g

Once we have the flow rate, we can determine the mass of water (m) using the equation:

mass = Q * density

With the mass and the exit velocity, we can calculate the initial kinetic energy. To achieve the desired velocity, the kinetic energy must increase. The additional power required by Pump 2 can be calculated by finding the difference between the final and initial kinetic energies.

Judging the best best film:

a. The probability that out of five judges (random sample),  three are in favor of film FA is:

= 33%.

b. The demerits of classical probability are:

1. Classical probability can only be used with events that have definite numbers of possible outcomes.  

2. Classical probability can only handle events where each outcome is equally likely.

3. Classical probability is based on the assumption of linear relationship (which is not always true in real life) between the latent variable and observed scores.

Explanation:

a) Number of judges = 11

Number of judges in favor of FA film = 6

Number of judges in favor of FB film = 5

Probability of judges in favor of FA film = 6/11

Probability of judges in favor of FB film = 5/11

Random sample of judges = 5

Probability that out of five judges, three are in favor of film FA = 3/5 * 6/11

= 18/55

= 33%

b) Classical probability is the simple probability showing that each event has equal chance of happening.  It can be contrasted with empirical probability that is obtained from experiments.

Explanation:

We resolve the component of the weight of the car along and perpendicular to the grade. We have mgsinФ and mgcosФ where Ф = angle of grade.

Now, the frictional force f = μN = μmgcosФ where μ = coefficient of friction

So, the net force along the grade is F = mgsinФ - μmgcosФ.

The work done by this force moving a distance, d along the grade is

W = (mgsinФ - μmgcosФ)d

This work equals the change in kinetic energy of the car. So ΔK = 1/2m(v₂² - v₁²) = W = (mgsinФ - μmgcosФ)d

1/2m(v₂² - v₁²) = (mgsinФ - μmgcosФ)d

1/2(v₂² - v₁²) = (gsinФ - μgcosФ)d

(v₂² - v₁²)/2d = (gsinФ - μgcosФ)

dividing through by gcosФ, we have

(v₂² - v₁²)/2dgcosФ = (gsinФ/gcosФ) - μgcosФ/gcosФ

(v₂² - v₁²)/2dgcosФ = tanФ -  μ

μ = tanФ - (v₂² - v₁²)/2dgcosФ

given that tanФ = 3% = 3/100 and 1 + tan²Ф = 1/cos²Ф, cosФ = 1/(√1 + tan²Ф) = 1/(√1 + (3/100)²) = 1/(√1 + (9/10000)) = 1/(√10000 + 9/10000) = 1/√(10009/10000) = 100/√10009 = 100/100.05 = 0.9995.

Also, given that v₁ = 90 km/h = 90 × 1000/3600 m/s = 25 m/s and v₂ = 45 km/h = 45 × 1000/3600 m/s = 12.5 m/s, d = 75 m and g = 9.8 m/s².

So, substituting the values of the variables into the equation, we have

μ = tanФ - (v₂² - v₁²)/2dgcosФ

μ = 3/100 - ((12.5 m/s)² - (25 m/s)²)/(2 × 75 m × 9.8 m/s² × 0.9995)

μ = 3/100 - ((156.25 m/s)² - (625 m/s)²)/1,469.265 m²/s²

μ = 3/100 - (-468.75 m²/s²)/1,469.265 m²/s²

μ = 3/100 + 468.75 m²/s²/1,469.265 m²/s²

μ = 0.03 + 0.32

μ = 0.35

So, theoretical friction  coefficient is 0.35
