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.

Lyrx [107]

Answer:

=IF(D3>50; E3; F3) AND =IF(A1>60;"Pass";"Fail")

Explanation:

An IF structure is built following this pattern:

IF(TEST;IFTRUE;IFFALSE)

These are the only options in the given drop-down menus what comply with this pattern. All others are not following this pattern.

write a loop that reads positive integers from stands input and that terinated when it reads an interger that is not positive af

gtnhenbr [62]

Loop takes only positive numbers and terminates once it encounters a negative numbers.

Answer and Explanation:

Using javascript:

Var positiveInt= window.prompt("insert positive integer");

While(positiveInt>=0){

Alert("a positive integer");

Var positiveInt= window.prompt("insert positive integer");

}

Or we use the do...while loop

Var positiveInt= window.prompt("insert positive integer");

do{

Var positiveInt= window.prompt("insert positive integer");

}

While (positiveInt>=0);

The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input
