How many times should the start function be defined in a program?

The equation of certain traveling waves is y(x.t) = 0.0450 sin(25.12x - 37.68t-0.523) where x and y are in

NNADVOKAT [17]

Answer:

A. 0.0450

B. 4

C. 0.25

D. 37.68

E. 6Hz

F. -0.523

G. 1.5m/s

H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

I. -1.67m/s.

Explanation:

Given the equation:

y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)

Standard wave equation:

y(x, t)=Asin(kx−ωt+ϕ)

a.) Amplitude = 0.0450

b.) Wave number = 1/ λ

λ=2π/k

From the equation k = 25.12

Wavelength(λ ) = 2π/25.12 = 0.25

Wave number (1/0.25) = 4

c.) Wavelength(λ ) = 2π/25.12 = 0.25

d.) Angular frequency(ω)

ωt = 37.68t

ω = 37.68

E.) Frequency (f)

ω = 2πf

f = ω/2π

f = 37.68/6.28

f = 6Hz

f.) Phase angle(ϕ) = -0.523

g.) Wave propagation speed :

ω/k=37.68/25.12=1.5m/s

h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.

Difference between switch case and if else statement.

ser-zykov [4K]

Answer:

<h3>SWITCH CASE:</h3>

☆ STATEMENT WILL BE EXECUTED IS DECIDED BY USER.

☆ SWITCH STATEMENT EVALUATES ONLY CHARACTER 《OR 》INTEGER VALUE.

☆ IT USING SINGLE EXPRESSION FOR MULTIPLE CHOICES.

<h3>IF - ELSE STATEMENT. </h3>

☆ STATEMENT WILL BE EXECUTED DEPEND UPON THE OUTPUT OF THE EXPRESSION INSIDE.

☆ IF THE STATEMENT EVALUATES INTEGER, CHARACTER, POINTER《 OR 》FLOATING- POINT TYPE 《 OR 》BOOLEAN TYPE.

☆ IF USING MULTIPLE STATEMENT FOR MULTIPLE CHOICES.

Mike needs to write the primary objectives of a project in a project plan. In which section should he write them?

Advocard [28]

Mike needs to write the primary objectives of a project in a project plan. He should write this under the SCOPE section of the project plan.

Explanation:

Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, features, functions, tasks, deadlines, and ultimately costs.
It is what needs to be achieved and the work that must be done to deliver a project.
The Scope of Work (SOW) is the area in an agreement where the work to be performed is described.
The SOW should contain any milestones, reports, deliverables, and end products that are expected to be provided by the performing party. The SOW should also contain a time line for all deliverables.
The scope is simply all the work that needs to be done in order to achieve a projects objectives.
A project scope, or project scope statement, is a tool used to describe the major deliverables of a project including the key milestones, high level requirements, assumptions, and constraints.

tatuchka [14]

Answer:

The word efficient denotes the ability to achieve a good goal toward a person, and effectiveness denotes reliable production or achievement.

Explanation:

Many people around the world can set efficient goals, that is, to influence or encourage other people to make good projects or changes in their lives, by example or simply teach them with patience and altruism.

In this way effectiveness will be seen, that is, the product or the achievement precisely when we observe how people undertake new projects in their lives
