Answer:

The answer to this question an be given as:

The other thing which can be purchased with your $50.

Explanation:

In the question the opportunity cost is "The other thing which can be purchased with your $50". Because you have only $ 50 as a birthday gift and you want to choose to buy new wallpaper for your room.If you buy only the wallpaper so you can't buy any other item. To solve this problem you should buy other item. It may be any thing you want. So the answer to this question is "The other thing which can be purchased with your $50".

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.

In the wireless telecommunications industry, different technical standards are found in different parts of the world. A technica
Serhud [2]

Answer:

A varying infrastructure.

Explanation:

The competitive pressure it creates for multinational companies in the industry is one of difference in infrastructure because different technical standards are found in different parts of the world.

For instance, A technical standard known as Global Systems for Mobile (GSM) is common in Europe, and an alternative standard, Code Division Multiple Access (CDMA), is more common in the United States and parts of Asia.

Consequently, equipment designed for GSM will not work on a CDMA network and vice versa as a result of varying infrastructure, so companies would be innovative in order to improve on their products.

Phoebe has to give a presentation about recycling. Where should she look while presenting?
Naddika [18.5K]
Well, I think that maybe the answer is B or C. She shouldn't only look at her presentation while she is presenting it, that doesn't look professional, and you want to look at the people you are talking to.

Answer:

this would be .128 terabytes

Explanation:

This would be since for a whole terabyte you need 1000 gigabytes every 1000 gigabytes is a terabyte for example let’s say you have 5250 gigabytes you would have 5.250 terabytes that simple hope this helped!
