Taking A, B, C and D as the selector pins (4 selector pins) build the following logic function using 8x1 MUX.
F (A, B, C, D) = Σ (0, 1, 3, 8, 10, 14)
ps. it's a 10 mark assignment. so please ensure quality

Answers

By connecting the pins A, B, C, D to the appropriate address lines and connecting the function outputs (0, 1, 0, 0, 0, 1) to the corresponding data inputs of the MUX, we can implement the logic function F(A, B, C, D) = Σ(0, 1, 3, 8, 10, 14) using the 8x1 MUX.

To build the logic function F(A, B, C, D) = Σ(0, 1, 3, 8, 10, 14) using an 8x1 MUX, we need to determine the truth table for the function and map it to the inputs and outputs of the MUX.

The truth table for F(A, B, C, D) is as follows:

Based on the truth table, we can see that the inputs A, B, C, D correspond to the address lines of the MUX, and the output F corresponds to the output of the MUX.

To build the logic function using an 8x1 MUX, we will connect the selector pins A, B, C, D to the address lines of the MUX, and the function outputs (0, 1, 0, 0, 0, 1) to the corresponding data inputs of the MUX. The output of the MUX will be the desired logic function F(A, B, C, D).

If you measure 0.7 V across a diode, the diode is probably made of

Answers

Answer:

Made of Silicon.

Explanation:

A diode is a semiconductor device use in mostly electronic appliances. It is two terminals device consisting of a P-N junction formed either in Germanium or silicon crystal.

Diode can be forward biased or reverse biased.

When a diode is forward biased and the applied voltage is increased from zero, hardly any current flows through the device in the beginning.

It is so because the external voltage is being opposed by the internal barrier voltage whose value is 0.7v for silicon and 0.3v for germanium.

If you measure 0.7 V across a diode, the diode is probably therefore made of Silicon.

Which of the following is an implication of low
variety?
A. low unit cost
B. flexibility needed
C. high complexity
D. matching customers specific needs
PLEASE EXPLAIN WHICH IS CORRECT WITH EXPLANATION

Answers

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety. In low variety, the company has a limited range of goods and services, so it is not possible to fulfill all the customers’ specific needs.

Suppose Host A and Host B are separated by 15,000 kilometers. A direct link with rate, R = 5Mbps connects the two hosts. Suppose a propagation speed of 2.5x108 meters/sec. What is the bandwidth delay if using ∙ pppppppp

Answers

To calculate the bandwidth delay product, we need to multiply the bandwidth (R) by the round-trip time (RTT). The RTT is the time it takes for a packet to travel from the source (Host A) to the destination (Host B) and back. So, the bandwidth delay product in this scenario is 0.6 megabits (Mb).

First, we need to calculate the RTT. The RTT is the time it takes for a signal to propagate from Host A to Host B and back. Since the distance between the hosts is 15,000 kilometers, and the propagation speed is 2.5x10^8 meters/second, we can calculate the RTT as follows:

RTT = (2 * distance) / speed

RTT = (2 * 15,000,000 meters) / (2.5x10^8 meters/second)

RTT = 0.12 seconds

Now, we can calculate the bandwidth delay product:

Bandwidth Delay Product = Bandwidth (R) * RTT

Bandwidth Delay Product = 5 Mbps * 0.12 seconds

Bandwidth Delay Product = 0.6 megabits

Thus, the answer is 0.6 megabits (Mb).

(a) (6 points) Find the integer a in {0, 1,..., 26} such that a = -15 (mod 27). Explain. (b) (6 points) Which positive integers less than 12 are relatively prime to 12?

Answers

a. a = 12 is the solution to the given congruence relation. b. the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

(a) The main answer: The integer a that satisfies a ≡ -15 (mod 27) is 12.

To find the value of a, we need to consider the congruence relation a ≡ -15 (mod 27). This means that a and -15 have the same remainder when divided by 27.

To determine the value of a, we can add multiples of 27 to -15 until we find a number that falls within the range of {0, 1,..., 26}. By adding 27 to -15, we get 12. Therefore, a = 12 is the solution to the given congruence relation.

(b) The main answer: The positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

Supporting explanation: Two integers are relatively prime if their greatest common divisor (GCD) is 1. In this case, we are looking for positive integers that have no common factors with 12 other than 1.

To determine which numbers satisfy this condition, we can examine each positive integer less than 12 and calculate its GCD with 12.

For 1, the GCD(1, 12) = 1, which means it is relatively prime to 12.

For 2, the GCD(2, 12) = 2, so it is not relatively prime to 12.

For 3, the GCD(3, 12) = 3, so it is not relatively prime to 12.

For 4, the GCD(4, 12) = 4, so it is not relatively prime to 12.

For 5, the GCD(5, 12) = 1, which means it is relatively prime to 12.

For 6, the GCD(6, 12) = 6, so it is not relatively prime to 12.

For 7, the GCD(7, 12) = 1, which means it is relatively prime to 12.

For 8, the GCD(8, 12) = 4, so it is not relatively prime to 12.

For 9, the GCD(9, 12) = 3, so it is not relatively prime to 12.

For 10, the GCD(10, 12) = 2, so it is not relatively prime to 12.

For 11, the GCD(11, 12) = 1, which means it is relatively prime to 12.

Therefore, the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

Describe TWO factors that need to be considered when selecting material for use as furnace linings.

Answers

When selecting materials for use as furnace linings, several factors need to be carefully considered. Two important factors are:

Temperature Resistance: Furnaces operate at high temperatures, and the chosen lining material must have excellent temperature resistance to withstand the extreme heat. Different furnaces may require different temperature capabilities, so it is crucial to select a lining material that can withstand the specific operating temperature range. Factors such as melting point, softening point, and thermal conductivity of the material should be evaluated to ensure it can handle the heat without deteriorating or deforming. High-temperature-resistant materials, such as refractory ceramics (e.g., alumina, silica, zirconia), refractory metals (e.g., molybdenum, tungsten), or specialized heat-resistant alloys, are commonly used for furnace linings.

Chemical Compatibility: Furnaces often involve various chemical processes and environments, such as oxidation, reduction, acidic or alkaline atmospheres, or exposure to corrosive gases. The selected lining material must be chemically compatible with these conditions to prevent degradation or chemical reactions that could compromise the integrity of the lining. It is important to consider factors such as resistance to chemical attack, stability in different atmospheres, and potential reactions with the process materials or by-products. Suitable lining materials may include refractory materials that are chemically inert or have specific chemical resistance properties, such as high-alumina refractories, silica-based refractories, or certain types of specialty coatings.

By carefully evaluating temperature resistance and chemical compatibility, the selection of a suitable lining material can ensure optimal performance, longevity, and safety of furnace operations.

\($\frac{101.325}{1000 \times 9.81}+0.02 =\frac{P_2}{\rho g}$\)

\($P_2 = 111.35 \ kPa$\)

Therefore, 111.325 kPa is the gas supply pressure required to keep the water from leaking back into the tube.

Velocity at point 2,

\($V_2=\sqrt{\left(\frac{111.135}{\rho g}+0.02}\right)\times 2g$\)

   = 1.617 m/s

Flow of water,  \($Q_2 = A_{tube} \times V_2$\)

                               \($=\frac{\pi}{4} \times (10^{-3})^2 \times 1.617 $\)

                               \($1.2695 \times 10^{-6} \ m^3/s$\)

Minimum air flow rate,

\($Q_2 = Q_3 = A_{hose} \times V_3$\)

\($V_3 = \frac{Q_2}{\frac{\pi}{4}D^2}$\)

\($V_3 = \frac{1.2695 \times10^{-6}}{\pi\times 0.25 \times 36 \times 10^{-6}}$\)

    = 0.0449 m/s

b). Reynolds number in hose,

\($Re = \frac{\rho V_3 D}{\mu} = \frac{V_3 D}{\nu}$\)

υ for water at 25 degree Celsius is \($8.9 \times 10^{-7} \ m^2/s$\)

υ for air at 25 degree Celsius is \($1.562 \times 10^{-5} \ m^2/s$\)

\($Re_{hose}=\frac{0.0449 \times 6 \times 10^{-3}}{1.562 \times 10^{-5}}$\)

           = 17.25

Therefore the flow is laminar.

Reynolds number in the pipe

\($Re = \frac{V_2 d}{\nu} = \frac{1.617 \times 10^{-3}}{8.9 \times 10^{-7}}$\)

                = 1816.85, which is less than 2000.

So the flow is laminar inside the tube.

T/F : The voltage through a resistor with current i(t) in the s-domain is sri(s).

Answers

False.

The voltage through a resistor with current i(t) in the s-domain is simply Ri(s), where R is the resistance value of the resistor. In the s-domain, the relationship between voltage and current through a resistor can be expressed using Ohm's law as V(s) = I(s)R.

Therefore, the voltage across a resistor in the s-domain is proportional to the current through it, with the proportionality constant being the resistance value. It's important to note that this relationship only holds true for resistive elements in linear circuits. Non-linear circuit elements such as diodes and transistors have much more complex voltage-current relationships that cannot be described using a simple linear equation.

The point of contact of two pitch circles of mating gears is called?

Answers

Answer:

the pitch point im pritty sure what is is

The point of contact of two pitch circles of mating gears is called the pitch point.

What is the pitch point?


A pitch point is where two pitch circles frequently come into touch. A common point of contact between two pitch circles of mating gears is called a pitch point. The pitch circle and is centered on the top of the teeth. Dedendum circle, also known as the root circle, is the circle traced through the base of the tooth.

The pressure angle, often known as the “tooth shape,” is the angle at which pressure from one gear's tooth is transferred to another gear's tooth. Pure rolling motion will occur at pitch point.

Therefore, it is pressure point.
