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

Reptile [31]

Complete Question:

The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.

Group of answer choices

a. Router

b. Switch

c. Bridge

d. Hub

Answer:

d. Hub.

Explanation:

A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.

<em>Hence, the main disadvantage of using a hub is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.</em>

almond37 [142]

Answer:

public static boolean beginsWithZ(String word){

if(string == null || string.length() == 0)

return 0;

if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')

return 1;

else

return 0;

}

Explanation:

This method is a boolean method, meaning it returns true if the string begins with Z or z and false otherwise. So:

The Java command charAt() let's you find the character at each position of the string, so i use it.

public static boolean beginsWithZ(String word){

if(string == null || string.length() == 0)

return 0;

if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')

return 1;

else

return 0;
