Answer:
The answer to this question is given below in the explanation section.
Explanation:
The value stored by a variable can be changed after it is assigned(true).
The value of a variable can be changed after it is assigned, for example:
int a=10;
and we can change the value of variable a in letter program such as:
a=15;
Variables are a name for a spot in the computer's memory (true).
it is true, because the variables value stored in the computer's memory and we can access theses values by their name (variable name). so Variables are a name for a spot in the computer's memory.
Variable names can be words: such as temperature or height (true).
Yes, the variable name can be words such as height, width, temperature etc.
The value stored by a variable cannot be changed after it is assigned (false).
It is noted that the value stored by a variable can be changed after it is assigned. However, it is noted that is some programming language, you can't change the value of static variable.
Answer:
Matlab / GNU Octave. MATLAB (laboratorio de matrices) es un entorno informático numérico multiparadigma y un lenguaje de programación de cuarta generación.
Explanation:
Answer:
words = ['is', 'NLP', 'fun', '?']
tmp = words[1]
words[1] = words[0]
words[0] = tmp
words[3] = '!'
print(words)
Explanation:
- Create the list
- Assign the new values using <em>tmp</em> variable
- Print the result
Since tuples in Python are unchangeable, you cannot transform the list using tuple assignment.
Answer:
I think the answer is D but please let me know if i am wrong
Explanation:
Mobile phones transmit and receive signals using electromagnetic waves, that is, wireless signal are electromagnetic waves which can travel through a vacuum, they do not need a medium or matter.
<h3>What are electromagnetic waves?</h3>
They are generated by electrical and magnetic particles moving at the same time (oscillating).
<h3>Characteristics of electromagnetic waves</h3>
- Network waves are electromagnetic waves.
- A mobile phone has coverage when it receives electromagnetic waves from at least one base station.
- They do not necessarily require a material medium for their propagation.
Therefore, we can conclude that electromagnetic waves are those that do not need a material medium to propagate and include, among others, radio, television and telephone waves.
