From the list of problems below, check all that are known to be NP-complete. You do not need to justify your answer. (Set cover)

White raven [17]

Any computing issue that falls within the category of NP-complete problem has yet to find an effective solution algorithm.

<h3>Which problems are NP-complete?</h3>

Any of a family of computer problems that have no effective solution algorithm are referred to as NP-complete issues.
The traveling salesman problem, satisfiability issues, and graph-covering issues are only a few examples of the significant computer science issues that fall under this category.
The difficulty of NP and NP-Complete issues is equal. If a problem is included in both NP and NP-Hard Problems, it is said to be NP-Complete.
This statement, "This problem can change into an NP-complete problem on a non-deterministic Turing machine," is untrue for the obvious reason that while any problem in P is also a problem in NP, no problem in P is an NP-complete problem (unless P=NP, of course). If P is an NP problem and all NP problems convert into NP-complete problems, then P must also undergo this transformation.

Writing an excellent problem statement will not help guide you through the rest of the process and steer you towards the BEST so

Ilya [14]

Answer:

Writing an excellent problem statement will not help guide you through the rest of the process and steer you towards the BEST solution.

False

Explanation:

An excellent problem statement sets the overall tone for the rest of the engineering process, whether it be at the analysis, design, or implementation stages. This is why a problem statement must be focused, clear, and specific. An excellent problem statement contains the problem definition, method for solving the problem (the claim proposed), purpose, statement of objectives, and scope. For an excellent problem statement to be effective, it must also show the gap that is to be closed to achieve the intended objective.

Annealing is a process by which steel is reheated and then cooled to make it less brittle. Consider the reheat stage for a 100-m

zvonat [6]

Answer:

T = 858.25 s

Explanation:

Given data:

Reheat stage for a 100-mm-thick steel plate ( 7830 kg/m3, c 550 J/kg K, k 48 W/m K),

initial uniform temperature ( Ti ) = 200 c

Final temperature = 550 c

convection coefficient = 250 w/m^2 k

products combustion temp = 800 c

calculate how long the plate should be left in the furnace ( to attain 550 c )

first calculate/determine the Fourier series Number ( Fo )

$\frac{T_{0}-T_{x} }{T_{1}-T_{x} } = C_{1} e^{(-0.4888^{2}*Fo )}$

= 0.4167 = $1.0396e^{-0.4888*Fo}$

therefore Fo = 3.8264

Now determine how long the plate should be left in the furnace

Fo = $(\frac{k}{pc_{p} } ) ( \frac{t}{(L/2)^2} )$

k = 48

p = 7830

L = 0.1

Input the values into the relation and make t subject of the formula

hence t = 858.25 s

A 1 m wide continuous footing is designed to support an axial column load of 250 kN per meter of wall length. The footing is pla

creativ13 [48]

Answer:

correct option is (A) 0.5

Explanation:

given data

axial column load = 250 kN per meter

footing placed = 0.5 m

cohesion = 25 kPa

internal friction angle = 5°

solution

we know angle of internal friction is 5° that is near to 0°

so it means the soil is almost cohesive soil.

and for a pure cohesive soil

$N_{\gamma }$ = 0

and we know formula for $N_{\gamma }$ is

$N_{\gamma }$ = (Nq - 1 ) × tan(Ф) ..................1

so here Ф is very less $N_{\gamma }$ should be nearest to zero

and its value can be 0.5

so correct option is (A) 0.5
