Answer:

C. Signal-to-quantization-noise ratio

Explanation:

Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53
(Cop) = 4.490

Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

The normal strain developed in each wire, Strain = ΔL / L = 4 mm / L. The factor of (2 mm / L) in the denominator is due to the horizontal displacement of point A being proportional to the length of the wire.

What is Normal Strain?

The normal strain in a wire can be calculated with given formula:

Strain = ΔL / L.

where ΔL is the change in wire-length and L is the original wire-length.

In this case, since the two wires are connected together at point A, they will experience the same amount of strain.

To find the strain in each wire, we first need to find the change in length of each wire due to the horizontal displacement of point A.

Let's assume that the length of each wire is L.

When point A is displaced horizontally by 2 mm, the change in length of each wire can be calculated as:

ΔL = 2 * (L / 2) * (2 mm / L) = 4 mm

Strain = ΔL / L = 4 mm / L.

Note that this calculation assumes that the wires are made of a linear elastic material and that their behavior can be modeled as a simple spring.

The required torque rating for a clutch to be attached to an electric motor shaft running at 1150 rpm is dependent on the specific application and load requirements.

To determine the required torque rating, we need to calculate the torque needed to drive the fan. We can use the formula:

Torque (in lb-ft) = (HP x 5252) / RPM

Substituting the given values, we get:

Torque = (0.50 x 5252) / 1150
Torque = 2.29 lb-ft

This means that the clutch must be able to transmit at least 2.29 lb-ft of torque to the fan. It is recommended to choose a clutch with a slightly higher torque rating to ensure reliability and prevent slip.

Additionally, the type of clutch needed will also depend on the specific application and operating conditions. For example, if the load on the fan varies, a clutch with adjustable torque settings may be required. If the clutch will be subjected to frequent start-stop cycles, a clutch with high durability and low wear characteristics would be ideal.

Overall, the required torque rating for a clutch depends on the load requirements and operating conditions, and it is important to choose a clutch that is appropriately sized and suited for the specific application.

The minimum weight of the cable will be X pounds.

To calculate the minimum weight of the cable, we need to consider the safety factor and the density of steel. The safety factor indicates the level of redundancy built into the design to ensure structural integrity. In this case, the safety factor is 2, meaning the cable needs to withstand twice the anticipated load.

The formula to calculate the minimum weight of the cable is:

Minimum weight = (Safety factor * Tensile strength * Cross-sectional area) / Density

Given the tensile strength of the steel (100,000 psi), the safety factor of 2, and the density of steel (0.283 lb/in^3), we can plug in these values into the formula to find the minimum weight of the cable. The cross-sectional area of the cable needs to be known to obtain the final weight.

In a delta-delta transformer connection, the line voltage on the secondary side is equal to the line voltage on the primary side divided by the turns ratio.

The given turns ratio is 10:1, which means that the secondary side voltage is one-tenth of the primary side voltage.

Therefore, the secondary line voltage can be calculated as:

Secondary Line Voltage = Primary Line Voltage / Turns Ratio

Secondary Line Voltage = 4800 V / 10

Secondary Line Voltage = 480 V
