To demonstrate that a problem is NP-complete, we appear that it is within the NP course and can be decreased to a known NP-complete problem. From this deduction, all the problems are NP-complete.

To demonstrate that a problem is NP-complete, we ought to appear that it is both within the NP complexity course which is as difficult as an existing NP-complete problem. Let's analyze each issue and appear how they can be seen as generalizations of known NP-complete problems:

(a) SUBGRAPH ISOMORPHISM: This problem generalizes the SUBSET-SUM problem, where rather than subsets and wholes, we have charts and subgraphs. SUBSET-SUM could be a well-known NP-complete issue, so SUBGRAPH ISOMORPHISM acquires its NP-completeness.

(b) LONGEST Way: This problem generalizes the HAMILTONIAN Way problem, where we are inquired to find a straightforward way of length rise to the number of vertices within the chart. HAMILTONIAN Way may be a known NP-complete issue, so LONGEST Way is additionally NP-complete.

(c) MAX SAT: This problem is as of now a known NP-complete problem, so no advance verification is required.

(d) Thick SUBGRAPH: This problem generalizes the CLIQUE problem, where we are inquired to discover a total subgraph of a certain size. CLIQUE could be a well-known NP-complete problem, so Thick SUBGRAPH acquires its NP-completeness.

(e) Inadequate SUBGRAPH: This problem can be seen as the complement of the Thick SUBGRAPH issue. Since Thick SUBGRAPH is NP-complete, its complement, Scanty SUBGRAPH, is additionally NP-complete.

(f) SET COVER: SET COVER may be a known NP-complete problem, so no encouraged confirmation is required.

(g) Solid Organize: This issue can be seen as a generalization of the HAMILTONIAN CYCLE  problem. In case all did values are limited to 1 or 2, rij values are all 2, and b is equal to n, the issue gets to be identical to finding a Hamiltonian cycle. Since HAMILTONIAN CYCLE is NP-complete, the Solid Arrange issue acquires its NP-completeness.

By finding the relationship between these problems and known NP-complete problems, we will conclude that they are all NP-complete.

Height of mirror is 0.075 m while width of mirror 0.325 m.

The distance between an object's two sides is considered to be its width. This is the smallest dimension. Height is the distance between the top and bottom of an object.

given data:

wide = 1.3 m

high = 0.30 m

driver’s eyes = 0.50 m

rear window = 1.50 m

we take here height / width of the mirror  is

height / width   =  h/w  .................1

and

height /width of the window is

height /width  = hw/ww    .................2

and

distance of eye / window by the mirror is

distance of eye / window = xe/xw      .................3

so here

θ = θi  = θr    ....................4

and  tanθ for vertical is

tanθ  =   h/xe

tanθ  =  hw/(xe+xw)       ....................5

so

h =     hw × xe/(xe+xw)    ....................6

put  here value and we get

h = 0.30 ×  0.5/(0.5+1.5)  

h = 0.075 m

and

when we take here tanθ for horizontal than it will be

tanθ =     w/xe

tanθ =   Ww/(xe+xw)     .......................7

so

w = Ww  × xe/(xe+xw)      ....................8

put here value and we get

w = 1.30 ×  0.5/(0.5+1.5)

what is the relative resolution (i.e. how many discrete levels are there) of an oscilloscope with 2^n, 8-bit D/A converter has 256 levels, 12-bit D/A converter has 4096 levels and 16-bit converter has 65536 levels.

In the system development and prototyping phases, oscilloscopes are of course the preferred tool for doing these measurements, but these are principally constrained by the vertical resolution of the scope's front-end. For instance, an 8-bit oscilloscope has a dynamic range of 256:1, therefore the theoretically lowest signal on a range of 1 volts is 3.9 millivolts (mV). Higher sensitivity and offset range are required to view millivolt level ripple signals on a 3.3 volt bus. Additionally, signal levels at the scope input will be muted when employing high attenuation probes to prevent circuit loading, making it difficult to measure them unless the instrument has a high resolution.

The ratio of the largest input signal an oscilloscope can handle to the smallest signal amplitude it can detect is known as oscilloscope vertical resolution. Resolution is often measured by the analog-to-digital converter's bit count (ADC). The resolution is equal to the amount of bits multiplied by two. The resolution of an 8-bit converter is therefore 28 or 256:1. The resolution of a 12-bit converter is 4096:1, which is 16 times higher than that of an 8-bit converter.

Efficiency is defined as any performance that uses the fewest number of inputs to produce the greatest number of outputs. Simply put, you're efficient if you get more out of less.

Explanation:

Gas (hydrogen) will replace the water in the eudiometer as it is created. Using "downward displacement" is what is meant by this.

Due to the acid's greater density than the water, it dips below the water. It pours down the tube spontaneously when it is turned upside down.

Today, chemistry uses eudiometers to measure the amount of oxygen in the air. An electric spark causes atmospheric air and hydrogen to erupt over water, and the rise in the water's level in the tube indicates the presence of oxygen.

Tour operators traveled with eudiometers throughout Europe searching for the ideal locations for health resorts. As a result of rotting garbage, human waste, and stagnant water, it was believed that disease was brought on by poor air quality and offensive odors.

In order to treat and prevent illness, clean air was therefore regarded as crucial—a picture of the eudiometer and a different instrument with a comparable design.

Explanation:

The maximum theoretical efficiency for any thermal engine is defined by Carnot's cycle, whose energy efficiency (\(\eta\)), no unit, is expressed below:

\(\eta = 1-\frac{T_{L}}{T_{H}}\) (1)

Where:

\(T_{L}\) - Cold reservoir temperature, in Kelvin.

\(T_{H}\) - Hot reservoir temperature, in Kelvin.

If we know that \(T_{L} = 250\,K\) and \(T_{H} = 750\,K\), then the maximum theoretical efficiency for the thermal engine is:

\(\eta = 1-\frac{T_{L}}{T_{H}}\)

\(\eta = 0.667\)

For real thermal engines, the following inequation is observed:

\(0 \le \eta_{r} \le \eta\) (2)

Where \(\eta_{r}\) is the efficiency of the real heat engine, no unit.

There are two possible criteria to determine if a given heat engine is real:

Efficiency

\(\eta_{r} = 1 - \frac{Q_{L}}{Q_{H}}\) (3)

Where:

\(Q_{L}\) - Heat rejected to the cold reservoir, in kilojoules.

\(Q_{H}\) - Heat received from the hot reservoir, in kilojoules.

Power output

\(W = Q_{H}-Q_{L}\) (4)

Where \(W\) is the power output, in kilojoules.

Now we proceed to verify each case:

A) \(Q_{H} = 900\,kJ\), \(Q_{L} = 600\,kJ\), \(W_{m} = 400\,kJ\)

\(\eta_{r} = 0.333\)

\(0 \le \eta_{r} \le \eta\)

\(W = 300\,kJ\)

\(W \ne W_{m}\)

This engine is not possible.

B) \(Q_{H} = 900\,kJ\), \(Q_{L} = 500\,kJ\), \(W_{m} = 400\,kJ\)

\(\eta_{r} = 0.444\)

\(0 \le \eta_{r} \le \eta\)

\(W = 400\,kJ\)

\(W = W_{m}\)

The engine is possible.

C) \(Q_{H} = 900\,kJ\), \(Q_{L} = 300\,kJ\), \(W_{m} = 600\,kJ\)

\(\eta_{r} = 0.667\)

\(0 \le \eta_{r} \le \eta\)

\(W = 600\,kJ\)

\(W = W_{m}\)

The engine is possible.

D) \(Q_{H} = 900\,kJ\), \(Q_{L} = 100\,kJ\), \(W_{m} = 800\,kJ\)

\(\eta_{r} = 0.889\)

\(\eta_{r} > \eta\)

\(W = 800\,kJ\)

\(W = W_{m}\)

Answer: I believe the answer is 963.75 if I am reading the question right.

Explanation:

ACH=60L/V

ACH=2.25

V=25,700

25,700*2.25=57,825

57,825/60=963.75

L=963.75

60(963.75)/25,700=2.25

The maximum amount of air leakage that would result in an ACH of no more than 2.25 would be approximately 956.25 cfm (cubic feet per minute).

Given that ACH of a house is a measure of its​ air-tightness and the formula for ACH is ACH = 60L/V. It means that ACH is inversely proportional to air-tightness or leakage. Therefore, the lower the air leakage the higher the ACH and vice versa.Mathematically, it is represented as:ACH ∝ 1/L or L ∝ 1/ACH

We can solve the question as follows:ACH = 2.25 (since the maximum ACH is 2.25)The volume of the house, V = 25,700 cubic feet.Substituting in the formula,2.25 = 60L/25,700Dividing both sides by 2.25 gives us,L = (2.25 * 25,700)/60L = 956.25 cubic feet per minute (cfm)

Therefore, the maximum amount of air leakage that would result in an ACH of no more than 2.25 is approximately 956.25 cfm (cubic feet per minute).
