Explanation:

Given that a transparent film is to be bonded onto the top surface of a solid plate inside a heated chamber. For the bond to cure properly, a temperature of 70°C is to be maintained at the bond, between the film and the solid plate. The transparent film has a thickness of 1 mm and thermal conductivity of 0.05 W/m·K, while the solid plate is 13 mm thick and has a thermal conductivity of 1.2 W/m·K. Inside the heated chamber, the convection heat transfer coefficient is 70 W/m2·K. If the bottom surface of the solid plate is maintained at 52°C.

To determine the temperature inside the heated Chamber, let us first calculate the heat transfer rate per unit area through the plate by using the formula

Heat transfer rate R = k( Tb - T2)/L

Where

k = 1.2 W/mA.K

Tb = 70 degree

T2 = 52 degree

L = 13mm = 13/1000 = 0.013m

substitute all the parameters into the formula above.

R = 1.2 x ( 70 - 52 )/ 0.013

R = 1.2 x (18/0.013)

R = 1661. 5 W/m^2

the surface temperature of the transparent film will be

Ts = Tb + (RLf/Kf)

Ts = 70 + (1661.5 x 0.001)/0.05

Ts = 70 + (1.6615)/0.05

Ts = 70 + 33.23

Ts = 103.23 degree centigrade

the temperature inside the heated Chamber will be calculated by using the formula

Ti = Ts + (R/h)

Ti = 103.23 + (1661.5/70)

Ti = 103.23 + 23.74

Ti = 126.97 degree centigrade

A chip without PMOS transistor is easier because pMOS transistor would not avaiable to offer a conductive path for a node all the way to the ground voltage.

Microprocessors are constructed out of transistors. In particular, they're built out of metal-oxide-semiconductor (MOS) transistors. There are kinds of MOS transistors — positive-MOS (pMOS) and negative-MOS (nMOS). Every pMOS and nMOS comes prepared with 3 primary components — the gate, the source, and the drain. NMOS and pMOS are the primary types of MOSFET. The primary difference between NMOS and pMOS is that, in NMOS, the source and the drain terminals are made from n-kind semiconductors meanwhile, in pMOS, the source and the drain are made from p-kind semiconductors.

The answer is , the work produced in the ideal Rankine cycle using steam as the working fluid is 22.29 kJ/kg.

The Ideal Rankine cycle is a thermodynamic cycle that describes the operation of a steam power plant. It is named after William John Macquorn Rankine, a Scottish engineer and physicist who developed it in the 19th century.

we can use the following steps:

Given:

Assuming,

State 1: Saturated vapor at the boiler pressure of 2 MPa.

State 2: Saturated liquid at the condenser pressure of 10 kPa.

State 3: Saturated liquid at the boiler pressure of 2 MPa (after the pump).

State 4: Saturated vapor at the condenser pressure of 10 kPa (after the turbine).

Using steam tables, we can find the specific enthalpy at each state as follows:

State 1: h1 = 2776.6 kJ/kg (from the saturated vapor table at 2 MPa)

State 2: h2 = 191.81 kJ/kg (from the saturated liquid table at 10 kPa)

State 3: h3 = h2 + v2(P1 - P2) = 191.81 + 0.00106(2 - 0.01) = 192.82 kJ/kg

State 4: h4 = h1 - v1(P1 - P2) = 2776.6 - 0.00618(2 - 0.01) = 2753.3 kJ/kg

Work produced by the turbine:

Wturbine = h1 - h4 = 2776.6 - 2753.3 = 23.3 kJ/kg

Work required by the pump:

Wpump = h3 - h2 = 192.82 - 191.81 = 1.01 kJ/kg

Net work produced:

Wnet = Wturbine - Wpump = 23.3 - 1.01 = 22.29 kJ/kg.

The spacing between sidebands is equal to 6 kHz.

Given the following data:

A sideband can be defined as a band of frequencies that are lower or higher than the carrier frequency due to the modulation process. Thus, it will either be lower than or higher than the carrier frequency.

Generally, the frequency of the modulating signal is equal to the spacing between the sidebands. Therefore, a modulating signal of 3 kHz simply means that the lower sideband is 3 kHz higher while the upper sideband is 3 kHz lower.

Spacing = 3 kHz + 3 kHz = 6 kHz.

(The diagram of the question is given in Attachment 1)

The largest load which can be applied is:

P=67.62 kN

Explanation:

All the forces are shown in the diagram in Attachment 2.

∑ 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:

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

To satisfy both the condition, we have to choose the lower value of P.

Explanation:

Latent heat is the hidden heat.

Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.

Thermometer can not detect the latent heat. That is why it is called hidden heat.

If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.

Absolute encoders are used to determine the angular position of a shaft and to avoid false counting when the shaft rotates. A binary code is used. Hence, option is A is correct.

An encoder is an electro-mechanical device that converts angular or linear motion into an electrical signal for feedback control. Encoders come in a variety of forms, but they all serve the same fundamental purpose: providing feedback on position, speed, and direction of rotating or linearly moving components. It is possible to use an encoder in a variety of industries and applications, from robots and automation to material handling and metalworking. Angular position is a vector that points from the center of the circle to any point on the circumference. It is the measure of the direction of the particle from the reference line or the origin in which it was initially positioned in a circular motion.

A binary code is a code that utilizes a two-symbol system to encode and decode data. It is a digital signal in which a bit of information can only have two possible states: 0 or 1. Binary coding is used in digital circuits and systems to represent and store data in a compact and efficient manner. Absolute encoders determine the angular position of a rotating shaft using a binary code. When the encoder rotates, the code track sends out a unique digital signal that corresponds to its precise location. Because each position is unique, absolute encoders can deliver high accuracy and avoid false counting.

Based on the given information, it is clear that the proposed public-key deterministic order-preserving encryption scheme cannot provide any reasonable level of security. An adversary who only knows the public key can efficiently decrypt any given ciphertext because the ciphertexts preserve the order of the plaintexts.

This means that an attacker can guess the plaintext value by using a binary search-like algorithm where they make a guess and ask if the ciphertext is less than or greater than their guess, eventually arriving at the plaintext value. This is similar to the game where one person guesses a secret number in a known interval chosen by the other person with the help of a few yes-or-no questions.

Since the message space is 1,..., 2*, i.e., 2* is the largest number in the message space, the number of guesses an attacker would need to make to decrypt the ciphertext is at most k (log base 2 of 2*) + 1. This is because a binary search can be used to find the plaintext value with at most k guesses, and the extra guess is for the final guess to confirm the value. Therefore, the efficiency of the attack is logarithmic in the size of the message space, which is not acceptable for a secure encryption scheme.

In conclusion, the proposed encryption scheme cannot provide any reasonable level of security due to its deterministic and order-preserving nature. As an independent consultant, it is important to advise against the use of this scheme for any sensitive data, as it can be easily decrypted by an attacker with knowledge of the public key.
