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.

Answer:
The correct answer to the following question will be "Magnetic medium".
Explanation:
Some storage device that portrays details or information using magnetic patterns is called a magnetic device.
- Magnetic tape, and hard drives are the commonly used magnetic storage devices.
- This will be the method by which magnetic methods are used to hold and retrieve information on tapes.
So, it's the right answer.
It may be D) because it is actually a simplified version of Google maps.
Answer:
See explaination
Explanation:
def sum_lengths(value_list):
total = 0
for x in value_list:
if (type(x)==int) or (type(x)==float):
total += x
return total
import java.util.Scanner;
public class MyClass {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
int x = scan.nextInt();
int y = scan.nextInt();
}
}
I hope this helps!
