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.
Out of the following, the only one that I see is not the basic role of a webmaster is replying to customers questions about the web site! Usually they have a specific job for that; like customer service etc. Hopefully that helps.
Answer:
The answer is "The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language".
Explanation:
In the given question some details are missing that is options of the question that can be given as follows:
A. The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language.
B. The program can also be represented as a binary code that reduces the likelihood of errors.
C. Binary code can not be used for binary code, because binary code can only represent data.
D. Some parts of the program, however, should be printed in a higher-level language for the operation.
The computer knows the only binary language, It is a form of 0 and 1, but this language can't be understood by the user. It will convert into high-level language, that is understood by the user, that's why this option is correct. In which accepts of option A, all options are wrong that can be described as follows:
- In option B, It is wrong, because the user may not understand binary language, and he can also be writing some wrong code that is converted in binary code, that will increase error.
- In option C and option D, is incorrect because all the data that is stored in the computer is in the form of binary code.
Answer:
integer
Explanation:
this data type must be a number, but it will always be a whole number, so boolean is not appropriate. This means that it will be integer data type
