Maxima and minima - Study guides, Class notes & Summaries

What does modality refer to? How does it appear on ER diagram? - ANSWERRefers to the MINIMUM number of times an instance in one entity can be associated with instance of another entity (minima) Appears as a 0 or 1 on the relationship line, next to cardinality Define: Referential Integrity - ANSWER- Requires that ALL foreign key values must either be fully NULL or match some primary key value 4 Ways Referential Integrity can be violated: - ANSWER- 1. Primary key is updated 2. Foreign key i...

INTRODUCTION Dear Student Welcome to MAT2615. We trust that you will find the mathematics studied in this module interesting and useful, and that you will enjoy doing it. THIS TUTORIAL LETTER CONTAINS INFORMATION TO FACILITATE YOUR STUDIES. PLEASE READ IT CAREFULLY AND KEEP IT FOR FUTURE REFERENCE. The delivery mode for this module is “blended”, which means that only some study material will be printed and posted to you. All study material which may include additional material will be...

What is meant by work function (2) - Minimum energy required by an electron to escape from (1) a metal surface (1) What is meant by ionisation energy? (2) - Minimum energy required to remove an electron from an atom (1) from the ground state (1) Why do emitted electrons have a kinetic energy that varies up to a maximum value? (4) - Energy of a photon is fixed/constant (1) Energy is required for electrons to overcome work function ø (1) Electrons deeper into/below the surface of the meta...

Ultrasound Sound generated above the human hearing range (typically 20 kHz) is called ultrasound frequency (f) The number of cycles completed in one second (cyrcle/second) the period (T) The time required to complete a full cycle The relation between frequency and period The relation between c, f, l and T Propagation распространение The longitudinal wave is a compressional wave in which the particle motion is in the same direction as the propagat...
