Answer: True
Explanation:
The lines connecting an entity with a relationship whether single or double line refer to another constrain called “Existence Dependency Constraint” (also called “Participation Constraint”).
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:
The following code is:
do // set do while loop
{
response = stdin.next();
}
while (response != "Y" || response != "y" || response != "N" || response != "n");
// terminate do while loop
Explanation:
The following code starts with do while loop whose variables has already declared and then we assume the availability of the variable "stdin" which references the Scanner object and write some code to execute inside the do-while loop.
A DBMS acts as a conduit between the database and the applications that will use it, enabling users to access, modify, and control how the data is arranged and optimized.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of relational databases. Data items are requested from the database by application programs, which are created using a combination of the DBMS's data manipulation language and a traditional programming language. The DBMS locates and provides the data elements requested by the application programs.
