Software application life cycle simply means the application of standard practices to software applications building.

This is an incomplete information. Therefore, an overview of the software application life cycle will be given. It's the process of planning, creating, testing, and deployment of an information system.

Software application life cycle is divided into six steps which are planing requirements, designing, building, documentation, testing, deployment, and maintenance.

Air flows steadily through a variable sized duct in a heat transfer experiment with a speed of u = 20 – 2x, where x is the dista

zysi [14]

Answer:

a) $a=-28m/s^{2}$

b) $\frac{dT}{dx}=-5 ^{o}C/m$

Explanation:

In order to solve this problem, we need to start by remembering how the acceleration is related to the velocity of a particle. We have the following relation:

$a=\frac{dv}{dt}$

in other words, the acceleration is defined to be the derivative of the velocity function with respect to time. So let's take our speed function:

u=20-2x

if we take its derivative we get:

du=-2dx

this is the same as writting:

$\frac{du}{dt}=-2\frac{dx}{dt}$

we also know that velocity is defined to be:

$u=\frac{dx}{dt}$

so we get that:

a=-2u

when substituting we get that:

a=-2(20-2x)

when expanding we get:

a=-40+4x

and now we can use this equation to find our acceleration at x=3, so:

a=-40+4(3)

a=-40+12

$a=-28 m/s^{2}$

the same applies to this problem with the difference that this will be the rate of change of the temperature per m. So we proceed and take the derivative of the temperature function:

T=200-5x

$\frac{dT}{dx}=-5$

so the rate of change is $-5^{o}C/m$

Determine the dimensions for W if W = P L^3 / (M V^2) where P is a pressure, L is a length, M is a mass, and V is a velocity.

Eva8 [605]

Correct answer is option E. No dimensions

As we know formula Pressure (P) is $\frac{F}{A}$

also,

Dimensional formula of Pressure is $M^{1}L^{-1}T^{-2}$
Dimensional formula of length is L
Dimensional formula of mass is M
Dimensional formula of velocity is $L^{1} T^{-1}$

So, as given W= $\frac{P*L^{3} }{M*V^{2} }$

Dimensional formula of W = $\frac{M^{1}L^{-1}T^{-2} L^{3} }{M^{1} L^{2}T^{-2} }$

since all terms get cancelled

Work is dimensionless i.e no dimensions

marishachu [46]

Explanation:

1. Circumference of the handle (where the effort is applied) is pi times diameter.

C = πd

C = 1.5π inches

C ≈ 4.71 inches

2. Mechanical advantage is the ratio of distance in over distance out.

MA = din / dout

MA = 1.5 / 0.25

MA = 6

3. Mechanical advantage is the ratio of force out over force in.

MA = Fout / Fin

6 = Fout / 10 lb

Fout = 60 lb

Talja [164]

Answer: information security managers

Explanation:

Information security managers is an individual in charge of making sure that company's or organization's equipments such as computers, network, data etc are protected against security breach, computer viruses, hackers, etc. The person also keep assets in confidentiality, integrity, and makes them available when needed. Failure to do this might lead to the loss of confidential data, security breach, cyber crimes, etc which will cause a serious set back in a company's operations especially in the information and technology department, it might also lead to fine sanctions from regulatory body for the failure to protect data, it will also lead to financial loss,etc.
