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.

Cómo se hacían antes las cosas que hoy en día se hacen apoyadas en aplicaciones y software?
KatRina [158]

Answer:

Las cosas que hoy en día se hacen apoyadas en aplicaciones y el software se hacían de manera manual, artesanal o empírica, es decir, antes del avenimiento de la era digital, las tareas que hoy se han automatizado o informatizado se realizaban de forma analógica, mediante procesos con una participación humana mucho más fuerte.

Así, por ejemplo, en el entrenamiento, la medición de variables por parte de los entrenadores respecto de los atletas era procesada de forma manual: la comparación de las distintas estadísticas era recopilada en formato físico, y analizada en forma personal por profesionales idóneos para tal tarea, mientras que hoy en día esa tarea se ha automatizado y es llevada a cabo por programas informáticos específicos.

A su vez, respecto de la tecnología, por ejemplo, el análisis de las variables de mercado y la subida o bajada de distintos valores era sistemáticamente analizada en forma manual, mientras hoy en día diversos programas permiten realizar un análisis técnico y financiero en forma digital.
