Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
Answer:
Advantages of Digital Multimeters:
1)They are more accurate than analog multimeters.
2)They reduce reading and interpolation errors.
3)The 'auto-polarity' function can prevent problems from connecting the meter to a test circuit with the wrong polarity.
4)Parallax errors are eliminated.
I hope this helps.
Answer:
I can give you the perimeter "algorithm" but not the flowchart.
Here you go:
p = w * 4
p = perimiter,
w = width/height
4 = the amount of sides needed.
perimeter = width * 4
to include both width and height, we would instead use:
perimeter = 2(width+height)
This also works with rectangles ^
--------------------------------------------------------------------------
To find an area, it is just width * height. This is also compatible with rectangles.
Answer:
choice c
Explanation:
score = score + 10
because the rest doesn't make since and score == score + 10 has an extra equal sign.

In order to compose music, EarSketch coders can use samples. Audio samples are located in the sound browser, in the left window, which allows for sound file search, and personal sound file upload. In the left section, users can also show the script browser.
No account is required to create projects or view existing projects. EarSketch comprises different elements: a curriculum, a digital audio workstation (or DAW), a code editor and console, and a sound browser.
Dissolves The dissolve is probably the most used transition in video editing. Also known as a cross-dissolve, this effect layers two clips together so there is a seamless transition from one picture to another. You see it everyday and probably don’t even notice it: and that’s the point.
Explanation:
EarSketch is web-based, which means users can access it with their web-browsers, and with no installation. No account is required to create projects or view existing projects.
