Answer:

Check the explanation

Explanation:

800A stands for a current of 800 Ampes and 900Hz stand for the frequency (the change in the electric field with time) of 900 Hz. In this video footage they’re trying to raise the 1 kg plate, and the major factor that is in charge in lifting the plate is the magnet field that is present. So the whole purpose of this experiment is attempting to produce a big enough magnetic force in order to lift the plate.

From the equation, we are aware that the bigger the current (800A) the bigger the magnetic force. Also, the bigger the frequency, the bigger the change in the electric field. therefore producing a bigger magnetic field and force. these figures have to be really large or larger enough to produce a powerful magnetic force strong enough to lift the plate.

Super Scores
Sindrei [870]

Answer:

Replace:

<em>//CODE HERE  </em>

<em>//output the max score for each section and compute & output total too.  </em>

with the following lines of codes:

<em>int num;  </em>

<em>for(int i=0; i<numtakes; i++) { </em>

<em>for(int j=0; j<numsections; j++) { </em>

<em>   cin>>num; </em>

<em>   if(num>maxScores[j]){ </em>

<em>       maxScores[j] = num;    } </em>

<em>}  } </em>

Explanation:

Your program is poorly formatted. (See attachment for correct presentation of question)

What's required of the us is to complete the source program.

The codes has been completed in the Answer section above, however, the line by line explanation is as follows:

<em />

<em>This line declares num that gets user for input for each entry</em>

<em>int num;  </em>

<em>This line iterates through the number of takes</em>

<em>for(int i=0; i<numtakes; i++) { </em>

<em>This line iterates through the number of sections</em>

<em>for(int j=0; j<numsections; j++) { </em>

<em>This gets user input for each entry</em>

<em>   cin>>num; </em>

<em>The following if condition determines the greatest entry in each section</em>

<em>   if(num>maxScores[j]){ </em>

<em>       maxScores[j] = num;    } </em>

<em>}  } </em>

<em>For further explanation, I've added the complete source file as an attachment where I used comments to explain each line.</em>
