This question is related to the emission of electrons when light shines on an metal. (Photoelectric effect)
With the classical theory, it was thought that increasing or decreasing the intensity of light would increase or decrease the kinetic energy of the electron.,
Another expected result was that time gap between when light strikes the metal and when electrons are ejected, would depend on the intensity of such light.
However, the experimental results were not consistent with the particle theory of light. So your answer is A.
Later on this effect was correctly explained by Einstein based on Planck's findings.
Answer:
#include <iostream>
using namespace std;
void matrix(){
int row = 5, col = 6;
int myarr[row][col];
for (int i = 0; i < 5; i++){
for (int x = 0; x < 6; x++){
if (i == 0){
myarr[i][x] = (x+1)*(x+1);
}else if ( x == 0){
myarr[i][x] = (i+1)*(i+1)*(i+1);
} else if ( i == x){
myarr[i][x] = (i+1);
} else{
myarr[i][x] = myarr[i-1][x] + myarr[i][x-1];
}
}
}
for (int i = 0; i < 5; i++){
for (int x = 0; x < 6; x++){
cout<< myarr[i][x] << " ";
}
cout<< "\n";
}
}
int main(){
matrix();
}
Explanation:
The C++ source code defines a two-dimensional array that has a fixed row and column length. The array is a local variable of the function "matrix" and the void function is called in the main program to output the items of the array.
Answer:
The answer is "freeze panes command".
Explanation:
To see the row heading information into the columns "X, Y, and Z" we use the freeze panes command, which Pick's the cells from rows and on the right side of the columns, where you scroll.
This tool allows you to block columns/row headings so, the first column /or top row will stay on the screen and you also scroll down or over to see the rest of the panel.

Answer:
When a programmer tries to access an item in an array cell whose index is greater than or equal to the array's logical size, this data element or item is garbage. This means that currently, the item is not the part of the program's useful data. Garbage contains objects or data which will not be used by a program running on it. So the value returned could be either of the two:
- Value would be an arbitrary or random number if it is an array of numbers. Arbitrary means that the value is not predefined or specified in advance.
- Value returned would be null if it is an array of objects.
