Answer:
The answer is Live Preview.
Explanation:
<em>Live Preview is a Powerpoint tool that helps the user to find out how a singular choice will change the appearance of the presentation, without committing any change. This application allows the user to edit any slide and see the changes without any risk of damaging the rest of the presentation.</em>
<em>It lets the user see how an actual change will look on the slide object before the user decides to accept or decline the change.</em>
<em>It is a powerful resource, because we know how handful it is to prepare a powerpoint presentation.</em>

Answer:
The correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}
Explanation:
The declaration given is:
int ar[3];
This means the array consists of three locations and is named as ar.
We know that the indexes are used to address the locations of an array and the index starts from 0 and goes upto to 1 less than the size of the array which means the indexes of array of 3 elements will start from 0 and end at 2.
Now in the given options we are using ndx variable to run the while loop.
So the code to assign zero to all elements of array will be
ndx = 0;
while(ndx<3)
{
ar[ndx] = 0;
ndx++;
}
Hence, the correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}
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.
