Explanation:
Symmetric key cryptography makes use of one key. The same key is used for both encryption and decryption. This is different from asymmetric cryptography where separate keys are used for the two operations. Some examples of symmetric cryptography include:
- Advanced Encryption Standard (AES)
- Data Encryption Standard (DES)
- Triple Data Encryption Standard (3DES)

Once enough charge has been separated in a growing storm, a lightning flash can occur. These normally travel within or between clouds (abbreviated CC) or from cloud to ground (CG). Most storms produce more CC than CG flashes--about six times as many in tropical storms and two times as many in midlatitudes. Sometimes a flash will travel from cloud to air or simply occur within "clear" air.
Exactly what triggers flashes is still uncertain and an area of continued research. It seems that very concentrated electric fields (perhaps at the ends of pointed surfaces or single particles) are needed to accelerate charged particles, or ions. Once moving with sufficient energy, the ions appear to blaze a path toward opposite charge in cascading fashion.
Answer:
The ER Diagram is in the attachment. And I an including the membership details in the use case:
Applicants: Coach will ask for iD.
if the application is not registered, coach sends to registration department.
Applicants registers-->> shows registration ID-->> goes to account section
Submits the fee->> goes to coach again-->>coach asks for fee sjip-->> On yes-->> entrance allowed else-->> sent to account section
Applicants apply for course-->>if prerequisite is met, registration allowed
else-->>registration denied
Note: If registration is allowed the applicant is sent to account section and
Also note:
First check, then registration, then course prerequisite check,then account->entrance
If registered->direct entry.
Explanation:
The answer is self explanatory.
