Suppose that 2 kg of O2 gas are allowed to expand isothermally (T 127 0^C) from an initial volume = of 10 liters to a final volume of 60 liters. How much work does the gas do on the piston? Select one: a. 372 kJ b. 272 kJ c. 172 kJ d. 472 kJ

a) Here, VL = 9v, IL = 50mA, Ir = 50mA for the network of RL= 180 ohms.

b) If RL = 470 ohms, then VL = 10v, IL = 21.276mA, Ir = 45.45mA

c) The value of RL that will establish maximum power conditions for the            Zener diode, R\(_{L_{(max)}}\) = 1.83 kΩ

d) The minimum value of RL to ensure that the Zener diode is in the "on" state R\(_{L_{(min)}}\) = 220 Ω

A Zener diode is a particular kind of diode made to consistently permit current to flow "backwards" (with inverted polarity) when a specific reverse voltage, called the Zener voltage, is reached.

A wide range of Zener voltages, some of which are even variable, are used in the manufacture of Zener diodes. The reverse conduction occurs in some Zener diodes with sharp,  highly dopped p - n junctions and low Zener voltages; in these cases, the Zener effect, named after Clarence Zener, is caused by electron quantum tunneling in the small gap between the p and n regions.

Avalanche breakdown also occurs during the operation of diodes with higher Zener voltages, which have a more gradual junction.

Water flows through two connected identical pipes at a rate of 3 kg/s. The first pipe has smooth walls, the second pipe has rough walls. Assuming that water may be treated as an incompressible fluid, the water velocity will be higher in the rough pipe.

Water velocity can be defined as the amount of water that passes through a unit area of a pipe per unit time. It is the ratio of the volume flow rate to the area of the pipe. The relationship between water velocity, pressure, and cross-sectional area is given by the continuity equation.The continuity equation states that the product of the area of a pipe and the velocity of water flowing through it is constant. Therefore, as the area of the pipe decreases, the water velocity increases, and as the area of the pipe increases, the water velocity decreases.

The equation is expressed as follows:A1V1 = A2V2Where A1 and V1 are the cross-sectional area and velocity of water flowing through the first pipe, respectively. A2 and V2 are the cross-sectional area and velocity of water flowing through the second pipe, respectively.As the pipes are identical, their cross-sectional areas are the same. Therefore, to maintain the continuity equation, the water velocity will be higher in the rough pipe than in the smooth pipe. Hence, the correct option is B. the rough pipe.

translates to no TV lines and no sound system hum.

Cooking in microwaves is quicker.

Explanation:

The smoothest signal is a sine wave, and sine waves are the basis of all functions.

Every other continuous periodic function is a basis function, which means that it can be described in terms of sines and cosines.

For instance, using the Fourier series, I can describe the fundamental Sinusoidal frequency and its multiples in terms of the triangle and square waves.

To write a program that prints my name to the center of the output screen on three different lines use the following code:

The code is as follows:
```

print("            My Name            ")
print("            My Name            ")
print("            My Name            ")
```
This code uses the `print` function to output the string "My Name" on three separate lines. However, to center the text on the screen, I added a series of spaces before and after the text. By adjusting the number of spaces, I can change the position of the text on the screen. It's worth noting that there are different ways to accomplish this task in Python. For example, I could use the `center` method to center the text automatically:

```
name = "My Name"
print(name.center(30))
print(name.center(30))
print(name.center(30))
```

This code uses the `center` method to center the text within a string that is 30 characters wide. By calling the method on the `name` variable, I can avoid repeating the same string multiple times. Ultimately, the approach you choose will depend on your personal coding style and the specific requirements of the task at hand.

Based on the torque requirement of 2,013 Nm, we can select a motor with a power rating of 7.5 kW or higher.

Power (P) = 4 kW

Speed (N) = 30 rev/min

Torque (T) = (60 x P) / (2 x pi x N) = (60 x 4,000) / (2 x pi x 30) = 2,013 Nm

Speed (N2) = N1 / (speed ratio of chain drive x speed ratio of gearbox)

where N1 is the speed required at the mixer, which is 30 rev/min

speed ratio of chain drive is 2:1

speed ratio of gearbox is 15:1

N2 = 30 / (2 x 15) = 1 rev/mi

It depends on the age and condition of the car's AC unit, as well as the cost of the compressor replacement. If the car is relatively new and the AC unit is in good condition, replacing the compressor may be a worthwhile investment to extend the life of the unit.

However, if the car is older or the AC unit has other issues, it may be more cost-effective to replace the entire unit instead of just the compressor.

Ultimately, the decision to replace the compressor on an AC unit in a car depends on a variety of factors and should be based on a careful assessment of the costs and benefits.

∑ F(y)= 0 (Upwards is positive)

\(F_{BC}sin\theta-P=0\\\frac{4}{5}F_{BC} - P=0\\F_{BC}=\frac{5}{4}P\\\\F_{BC}=1.25P\)

∑ F(x)= 0 (Towards Right is positive)

\(N_{a-a} - F_{BC}cos\theta=0\\N_{a-a}-1.25P(\frac{3}{5})=0\\N_{a-a}=0.75P\)

∑ F(y)= 0 (Upwards is positive)

\(F_{BC}sin\theta- V_{a-a}= 0\\(\frac{4}{5})1.25P-V_{a-a}=0\\V_{a-a}=P\)

The cross sectional area of a-a:

\(A_{a-a}= \frac{(0.026)(0.026)}{3/5}\\A_{a-a}= 1.127\cdot10^{-3}\)

σ = N(a-a)/A(a-a)

Substitute values:

\(160\cdot10^6=\frac{0.75P}{1.127\cdot10^{-3}}\\P=240.42\cdot10^3 N\\P=240.42 kN\)

Т= V(a-a)/A(a-a)

Substitute values:

\(60\cdot10^6=\frac{P}{1.127\cdot10^{-3}}\\P=67.62\cdot10^{3}N\\P=67.62kN\)

Explanation:

The pressure inside the pipe can be given in terms of the elevation, by the following formula:

P = ρgΔz

where,

P = Absolute Pressure = ?

ρ = Density of Water = 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

Δz = elevation = 52 m

Therefore,

P = (1000 kg/m³)(9.8 m/s²)(52 m)

P = 509.6 KPa

Now, for gauge pressure:

Gauge Pressure = P - Atmospheric Pressure

Gauge Pressure = 509.6 KPa - 101.3 KPa

Answer:

\(I = 45mA\)

Explanation:

Given

\(I = 90mA\) --- Current

Required

Determine the new current when resistance is doubled

Using \(V = IR\)

Initially, we have:

\(V = 90mA * R\)

When resistance is doubled and voltage remains unaltered, we have:

\(V = I* 2R\)

2R represents the new resistance and I represents the new current

Equate both values of V

\(90mA * R = I* 2R\)

Make I the subject

\(I = \frac{90mA * R}{2R}\)

\(I = \frac{90mA }{2}\)

\(I = 45mA\)

The new current is 45milliAmps

Since the vehicle vibrates at highway speed. technician a says that water in the tire(s) could be the cause. Both Technician A and Technician B could be correct.

Technician A says that the reason for the vibrations might be water in the tire(s). If there is a lot of water in the tire, it can make the tire unbalanced and cause shaking when driving fast. This can happen if the tire is not closed tightly or if there is a hole that lets  water inside. In these situations, taking out the water and sealing the tire correctly should fix the problem.

Technician B thinks that a tire that is not perfectly round could be the reason. If a tire is not perfectly circular and has bumps or uneven areas, it is said to be out of round.
