Answer:

Use a non digital multimeter.

Explanation:

If a digital multimeter displays "000" when reading amperage, the technician should adjust the multimeter to a higher amperage range.

This is because "000" typically indicates that the current being measured is too low for the current range selected on the multimeter.

By switching to a higher amperage range, the technician can get a more accurate reading and ensure that the multimeter is properly measuring the current in the circuit under test.

The addition of the 3d pen to the U.S.A market would be viewed as a market-development strategy on ansoff's opportunity matrix.

Market can be defined as a space where buyers and sellers come together to exchange goods and services. It can be a physical place, such as a street market, a farmers' market, a flea market, or an online marketplace. In a market economy, the laws of supply and demand regulate prices and determine what goods are available and how they are produced. Markets are essential in any economy, and they are the most efficient way to allocate resources. Markets create competition, which helps to keep prices low and quality high. By allowing sellers to compete for buyers’ business, markets also provide consumers with a wide variety of products to choose from. Markets also allow for the efficient allocation of resources, since the demand for a product will drive the production of it. In short, markets are essential for economic growth and prosperity.

Answer:

ΔQ = 1.06 KJ

Explanation:

The amount of heat transfer between the piston-cylinder system and the surrounding can easily be found by using the First Law of Thermodynamics. The first law of thermodynamics can be written as follows:

ΔQ = ΔU + W

ΔQ = mΔu + PΔV

where,

ΔQ = Heat transfer between system and surrounding = ?

Δu = specific change in internal energy of the system = - 175 KJ/kg

m = mass of air = 20 g = 0.02 kg

P = Constant Pressure = 101.3 KPa

ΔV = Change in Volume = 0.05 m³ - 0.005 m³ = 0.045 m³

Therefore,

ΔQ = (0.02 kg)(-175 KJ/kg) + (101.3 KPa)(0.045 m³)

ΔQ = -3.5 KJ + 4.56 KJ

ΔQ = 1.06 KJ

tech A is more correct in saying that ear protection should be worn when 85 decibels sound levels exceed 85 decibels.

However, it's also important to note that exposure time is a factor in determining the level of risk. For example, exposure to 85 dB for 8 hours a day can cause damage over time, while exposure to 100 dB for the same amount of time can cause immediate damage. Additionally, some individuals may be more sensitive to loud sounds and may require ear protection at lower dB levels.

In summary, tech A's statement that ear protection should be worn when sound levels exceed 85 decibels is more accurate. However, it's important to consider exposure time and individual sensitivity when determining the level of risk and need for ear protection.

The answers to dry unit weight, void ratio, porosity, degree of saturation, volume occupied by water are respectively;

γ_d = 108.93 lb/ft³; e = 0.56; n = 0.36; S = 0.58; V_w = 0.021 ft³

We are given;

Moist weight; W = 12.2 lb

Volume of moist soil; V = 0.1 ft³

moisture content; w = 12% = 0.12

Specific gravity of soil solids; G_s = 2.72

A) Formula for dry unit weight is;

γ_d = γ/(1 + w)

where γ_w is moist unit weight as;

γ_w = W/V

γ_w = 122/0.1 = 122 lb/ft³

Thus;

γ_d = 122/(1 + 0.12)

γ_d = 108.93 lb/ft³

B) Formula for void ratio is;

e = [(G_s * γ_w)/γ_d] - 1

e = [(2.72 * 122)/108.93] - 1

e = 0.56

C) Formula for porosity is;

n = e/(1 + e)

n = 0.56/(1 + 0.56)

n = 0.36

D) Formula for degree of saturation is;

S = (w * G_s)/e

S = (0.12 * 2.72)/0.56

S = 0.58

E) Volume occupied by water is gotten from;

V_w = S*V_v

where;

V_v is volume of voids = nV

V_v = 0.36*0.1

V_v = 0.036 ft³

Thus;

V_w = 0.58 * 0.036

V_w = 0.021 ft³

Answer:

La diferencia media logarítimica de temperatura del intercambiador en paralelo es aproximadamente 75.466 ºC.

La diferencia media logarítmica de temperatura del intercambiador en contracorriente es aproximadamente 97.881 ºC.

Explanation:

De la teoría de Transferencia de Calor tenemos que un intercambiador de calor en paralelo presenta las siguientes dos características:

1) Tanto el fluido caliente como el fluido frío entran por el mismo lado.

2) Tanto el fluido caliente como el fluido frío salen por el mismo lado.

Mientras que el intercambiador de calor en contracorriente tiene que:

1) El fluido caliente y el fluido frío entran por lados opuestos.

2) El fluido caliente y el fluido frío salen por lados opuestos.

A continuación, anexamos los esquemas de perfil de cada intercambiador.

Ahora, la Diferencia Media Logarítimica de Temperatura (\(\Delta T_{lm}\)), medida en grados Celsius, queda definida como sigue:

\(\Delta T_{lm} = \frac{\Delta T_{1}-\Delta T_{2}}{\ln \frac{\Delta T_{1}}{\Delta T_{2}} }\) (Eq. 1)

Donde \(\Delta T_{1}\) y \(\Delta T_{2}\) son las diferencias de temperatura de los fluidos en cada extremo del intercambiador, medido en grados Celsius.

Procedemos a determinar esas diferencias y la Diferencia Media Logarítimica de Temperatura para cada configuración:

Intercambiador en paralelo

\(\Delta T_{1} = 180\,^{\circ}C-3\,^{\circ}C\)

\(\Delta T_{1} = 177\,^{\circ}C\)

\(\Delta T_{2} = 78\,^{\circ}C - 55\,^{\circ}C\)

\(\Delta T_{2} = 23\,^{\circ}C\)

\(\Delta T_{lm} = \frac{177\,^{\circ}C-23\,^{\circ}C}{\ln \frac{177\,^{\circ}C}{23\,^{\circ}C} }\)

\(\Delta T_{lm} \approx 75.466\,^{\circ}C\)

La diferencia media logarítimica de temperatura del intercambiador en paralelo es aproximadamente 75.466 ºC.

Intercambiador en contracorriente

\(\Delta T_{1} = 180\,^{\circ}C-55\,^{\circ}C\)

\(\Delta T_{1} = 125\,^{\circ}C\)

\(\Delta T_{2} = 78\,^{\circ}C-3\,^{\circ}C\)

\(\Delta T_{2} = 75\,^{\circ}C\)

\(\Delta T_{lm} = \frac{125\,^{\circ}C-75\,^{\circ}C}{\ln \frac{125\,^{\circ}C}{75\,^{\circ}C} }\)

\(\Delta T_{lm} \approx 97.881\,^{\circ}C\)

La diferencia media logarítmica de temperatura del intercambiador en contracorriente es aproximadamente 97.881 ºC.

The impulse response of the matched filters to the signals is a rectangular pulse.The probability of error can be determined using the formula: Pe = Q(sqrt(2Eb/No)), where Q is the Q-function, Eb is the energy per bit, and No is the noise power-spectral density.

In an additive white Gaussian noise (AWGN) channel with the noise power-spectral density of No/2, two equi-probable messages are transmitted. The transmitted signals are represented by s1(t) and s2(t), where s1(t) is a rectangular pulse of duration T and s2(t) is a rectangular pulse of duration -T. The impulse response of the matched filters to these signals is also a rectangular pulse of duration T. The matched filters are used to maximize the signal-to-noise ratio at the output.

The structure of the optimal receiver involves passing the received signal through the matched filters, followed by samplers that sample the filtered signal at the symbol rate. The sampled signals are then fed into decision devices that make a decision on which message was transmitted based on the received samples.

To determine the probability of error, we can use the formula Pe = Q(sqrt(2Eb/No)), where Eb is the energy per bit and No is the noise power-spectral density. The energy per bit can be calculated as Eb = Es/T, where Es is the energy per symbol and T is the symbol duration. By substituting the given values, the probability of error can be computed.

Answer:

Explanation:

To design a kettle that turns off the stove when the temperature reaches 100 degrees using the 8051 microcontroller, you would need to follow these steps:

Connect a temperature sensor to the 8051 microcontroller, such as a thermistor or a thermocouple.

Write a program in assembly language or C that reads the temperature data from the sensor and compares it to a set point of 100 degrees.

If the temperature exceeds 100 degrees, the program should send a signal to a relay or a transistor connected to the stove, turning it off.

Test the program and debug as necessary.

Once the program is working as expected, burn the program into the microcontroller's flash memory.

Assemble the circuit and connect the microcontroller, sensor, and stove according to the circuit diagram.

Please note that the 8051 microcontroller can be programmed using many different languages, the above steps are general steps that should be followed but the specific implementation details will be different depending on the programming language and the sensor you are using.

Answer:

To design a kettle using the 8051 microcontroller that turns off the stove when the temperature reaches 100 degrees, the following steps can be followed: Connect a temperature sensor to the 8051 microcontroller. The sensor should be able to measure the temperature of the kettle and send the data to the microcontroller.

Using the 8051 assembly language, write a program that continuously monitors the temperature data received from the sensor.

In the program, set a threshold temperature of 100 degrees.

Create an IF-ELSE statement that compares the temperature data with the threshold temperature. If the temperature data is equal to or greater than the threshold temperature, the program should activate a relay or switch that turns off the stove.

Once the program is written, test it to ensure that it functions correctly.

Burn the program into the microcontroller's memory and connect it to the kettle's stove and temperature sensor.

Test the kettle by turning on the stove and monitoring the temperature as it increases. The stove should turn off when the temperature reaches 100 degrees.

Explanation:

Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.

Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.

The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.

The chemical reaction that occurs in both alkali cations and hydroxyl ions in the pore solution of hydrated cement paste and certain reactive silica phases present in concrete aggregates is known as the alkali-silica reaction (ASR).

dA/A = dP/ρV² (1-M²) for supersonic flow Mach Number, M: M > 11 - M² < 0 (dA/A) = -K (dP/ρV²)k = 1-M²

Supersonic flow fields have Mach numbers greater than one at every location. Supersonic flows are usually characterized by the presence of shock waves, which cause abrupt changes in flow characteristics and streamlines (in contrast to the smooth, continuous variations in subsonic flows).

Supersonic and subsonic relate to speeds that are faster or slower than the speed of sound, respectively. Supersonic means traveling faster than the speed of sound, which is 343.2 m/s (1,126 ft/s). Subsonic speeds are defined as anything moving slower than the speed of sound.
