Answer:
Option b outFile.open("outputData.out");
Explanation:
In C++, there are several classes given to handle output and input of characters to or from files. They are:
- ofstream that write on files
- ifstream that read from files
We can use an object of ofstream to hold the contents that we wish to output to an external file. The general syntax is as follows:
ofstream_obj.open(file_name)
This will create a file with a specific file name and it possesses all the contents from the obstream_obj.
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.
Answer:
Boolean
Explanation:
Boolean is one of the primitive data types that will only hold either true or false value. This data type is commonly used in a variable that will track a status with only two possible outcomes.
For example, the<em> ParticipantPD</em> field is to track the payment status (paid or unpaid) of a participant. So, declare the<em> ParticipantPD</em> field as boolean data type will meet its purpose.
boolean ParticipantPD = true;
or
boolean ParticipantPD = false;
The answer to this question is a hanging indent. A hanging
indent is a writing format where in the first line of the text or paragraph is
being aligned in the left margin. A hanging indent is also known as the hanging
paragraph.
The assignment is about Telephone, internal combustion engine, and electrical light.
<h3>What is file?</h3>
A file is a computer system container for storing data. Files used in computers are similar in characteristics to paper documents used in libraries and office files. There are different types of files like text files, data files, folders, binary and graphic files and these different types of files store different types of data. A computer's operating system can store files on optical discs, hard drives, or other types of storage devices.
In most operating systems, a file must have a unique name within a specific directory. However, when creating a file name, some characters are considered illegal and therefore cannot be used. A file name consists of a name with an extension, also known as a file extension. The file extension is the two to four characters after the period of the full file name.
