Answer:

None of these is correct.

Explanation:

The wave particle duality has to do with Louis de Broglie's proposition that matter could exist as waves or particles.

According to him, matter poseses an associated wavelength. Hence, a certain wavelength is traceable to the hydrogen atom.

This wavelength is the ratio of Plank's constant to the momentum of the hydrogen atom

Match each titration term with its definition.
Illusion [34]

Answer:

1) titration

2) titrand

3) equivalence point

4) titrant

5) Burette

6) Indicator

Explanation:

The process in which a known volume of a standard solution is added to another solution so that the standard solution can react with the solution of unknown concentration such that its concentration is determined  can be referred to as titration.

The solution which is added to another solution  is called the titrant.  The titrand is the solution of unknown concentration

A burette is a glassware used to slowly add a known volume of the titrant to the titrand.

The indicator used signals the point when the reaction is complete by a color change. At this point, a stoichiometric amount of titrant has been added to the titrand. This is also referred to as the equivalence point.

Any collection of data or information that has been properly structured for quick search and retrieval by a computer is referred to as a database, often known as an electronic database.

<h3>What is electronic database?</h3>
  • Databases are designed to make it easy to save, retrieve, edit, and delete data while carrying out various data-processing tasks. In response to queries, a database management system (DBMS) retrieves data from the database.
  • Databases are briefly discussed after that. See computer science: Information systems and databases; information processing for a comprehensive explanation.
  • A file or collection of files used to store a database.
  • These files' contents can be divided up into records, each of which has one or more fields.
  • The fundamental units of data storage are fields, and each field typically contains data related to one feature or attribute of the thing that the database is describing.
  • Additionally, records are arranged into tables that contain details on the connections between their various fields.
  • A database in the strict sense offers cross-referencing capabilities, despite the fact that the term "database" is used broadly to refer to any collection of information in computer files.
  • Users can quickly search, rearrange, organize, and choose the fields in numerous records to access or produce reports on certain data aggregates using keywords and a variety of sorting instructions.

Natali [406]

Answer:

Sarah is asking each department head how long they can be without their primary system. Sarah is trying to determine the Recovery Time Objective (RTO) as this is the duration of time within which the primary system must be restored after the disruption.

Recovery Point Objective is basically to determine the age of restoration or recovery point.

Business recovery and technical recovery requirements are to assess the requirements to recover by Business or technically.

Hence, Recovery Time Objective (RTO) is the correct answer.
