Answer:

Power = 1920 Watts or 1.92 Kilowatts

Explanation:

Given the following data;

Resistance = 30 Ohms

Voltage = 240 Volts

To find power rating of the kettle;

Mathematically, the power consumption of an electric device is given by the formula;

Power = voltage²/resistance

Substituting into the formula, we have;

Power = 240²/30

Power = 57600/30

Power = 1920 Watts or 1.92 Kilowatts

tia_tia [17]

Answer:

b. Network performance monitor

Explanation:

A utility tool can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.

In the context of increasing security for the end users, the most important utility tools are;

1. Antivirus utility: to scan, detect, remove and prevent computer viruses such as Malware, Trojan horses, keyloggers, botnets, adwares etc.

2. Rootkit utility: it can be used to detect and remove any rootkit program that is hidden in a computer.

3. Spyware utility: this is used to detect, remove and prevent malicious adware that are found in software applications.

<em>However, a network performance monitor is a utility tool that would be found to least support an agent in increasing security for end users because it is a utility tool that is primarily used to monitor network traffic and amount of data usage. </em>
