Answer:
Effective reach and Frequency
Explanation:
Effective Reach is percentage of target audience that is exposed to a particular ad and receives given message to affect sales and purchase who are reached at or above effective frequency level. Here effective frequency level is the number of exposures necessary to make an impact and attain communication goal.
Effective reach is used in application of statistics to advertising and media analysis to calculate the effectiveness of ad and means used for ad. Effective reach is a time-dependent summary of aggregate audience behaviour.

The three best practices that can help defend against social engineering attacks are:
- Do not provide password resets in a c.ha.t window.
- Resist the urge to click on enticing web links.
- Educate employees regarding policies.
<h3>What is Social Engineering?</h3>
This refers to the art of manipulation of people through social interactions with the aim of getting access to sensitive information that gives unauthorized access.
Hence, we can see that some of the best practices that can be used to defend against social engineering include not clicking on suspicious links, educating people about the dangers, etc.

Explanation:
1.3 PHYSICAL AND CHEMICAL PROPERTIES
Learning Objectives
By the end of this section, you will be able to:
Identify properties of and changes in matter as physical or chemical
Identify properties of matter as extensive or intensive
The characteristics that enable us to distinguish one substance from another are called properties. A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed. Other physical properties, such as the melting temperature of iron or the freezing temperature of water, can only be observed as matter undergoes a physical change. A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter). We observe a physical change when wax melts, when sugar dissolves in coffee, and when steam condenses into liquid water (Figure 1). Other examples of physical changes include magnetizing and demagnetizing metals (as is done with common antitheft security tags) and grinding solids into powders (which can sometimes yield noticeable changes in color). In each of these examples, there is a change in the physical state, form, or properties of the substance, but no change in its chemical composition.
