A variable is something that represents, or stands in for something unknown, for example a number. You could be given the math problem 6 + x = 9, in which you would have to figure out what the variable is, which, in this situation, is x.

Is tbsp larger than fl oz?
it is avariable
What is avariable in an experiment?
justabout anything can be a variable. ex. Temperature, Mass, time, weight, etc.
When avariable appears in the denominator of one or more terms it is called?
It is a variable fraction. The exact nature will depend on the form in which the variable appears:as part of an algebraic, trigonometric, etc function. In some cases the fraction will have a name, in others it will not.
What is the scope of c?
Describe the concept of Scope :Incomputer programming, ascopeis the context within acomputer programin which avariable nameor other identifier is valid and can be used, or within which adeclarationhas effect. Outside of the scope of a variable name, the variable's value may still be stored, and may even be accessible in some way, but the name does not refer to it; that is, the name is notboundto the variable's storage
What is block structured programming language?
block-structured definitionlanguageAny programming language in which sections of source code contained within pairs of matching delimiters such as " " and "" (e.g. in C) or "begin" and "end" (e.g. Algol) are executed as asingle unit. A block of code may be the body of a subroutine orfunction, or it may be controlled by conditional execution ( if statement) or repeated execution ( while statement, for statement, etc.).In all but the most primitive block structured languages avariable's scope can be limited to the block in which it is declared.Block-structured languages support structured programming whereeach block can be written without detailed knowledge of the innerworkings of other blocks, thus allowing a top-down design approach.
Is the human memory a certain size?
"The human brain contains about 50 billion to 200 billion neurons(nobody knows how many for sure), each of which interfaces with 1,000to 100,000 other neurons through 100 trillion (10 14) to 10quadrillion (10 16) synaptic junctions. Each synapse possesses avariable firing threshold which is reduced as the neuron is repeatedlyactivated. If we assume that the firing threshold at each synapse canassume 256 distinguishable levels, and if we suppose that there are20,000 shared synapses per neuron (10,000 per neuron), then the totalinformation storage capacity of the synapses in the cortex would be ofthe order of 500 to 1,000 terabytes. (Of course, if the brain'sstorage of information takes place at a molecular level, then I wouldbe afraid to hazard a guess regarding how many bytes can be stored inthe brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"
Which operator is use to find address of a variable?
The dereference operator. In C, we use the * operator for this. Note that the * symbol has several meanings in C (multiplication, pointer declaration and pointer dereferencing). The meaning is determined from the context in which it is used. int x, y; /* integer variables */ int* p; /* pointer variable (pointer to int) */ x = 42; /* assign a value to the x variable */ p = &x; /* assign the address of the x variable to the pointer variable p */ y = *p; /* assign the value pointed to by p (42) to the variable y */
Features of structured programming language?
Structured programming language is actually a concept used to improvise the code over common procedural language. Structured programming is somewhat similar to Object Oriented Programming or OOP, which are blocks of code from sub-routines that define a program's functionality. Here are the features: · Division of large problems into small procedures and functions · Absence of Go to statement · Main statements include If-then-else, call, and case statements · Inclusion of facilities for declaring entry points and external references · Extensive set of operators include arithmetic, relational, logical, bit manipulation, shift, and part word operators
What models can you make in physics for class 12th?
you can make a model showing torque on a circular current loop. it's very simple and you can make it yourself...================================Suggestion #2:The best model would be one that has something to do with something youlearned, or something that was taught, in Physics class 12th. Somebody whowas there could tell you what was covered, and then you could model it. Theteacher would love it.================================Suggestion #3:Hey!

How much human brain memory capacity?
2 gb according to my mate Antony*Edit* Lol, try something like 2 Terabytes and you are still going to be very far from the truth. I don't think that it is possible (yet) to evaluate the capacity of the human brain. The fact is that a person can remember hundreds of movies, songs, books, events from the past, pictures, faces, names, phone numbers, etc., that if all those memories had to be put on a hard drive, terabytes upon terabytes wouldn't be enough.A quote from some researchers."The human brain contains about 50 billion to 200 billion neurons(nobody knows how many for sure), each of which interfaces with 1,000to 100,000 other neurons through 100 trillion (10 14) to 10quadrillion (10 16) synaptic junctions.
