Answer:
C. a current that rapidly switches direction
Explanation:
An audio speaker is an electronic device that converts electrical signals into sound energy (waves). The alternating current flowing into the audio speaker is typically used to generate sound waves.
Hence, what causes the poles of the electromagnet in an audio speaker to repeatedly switch directions is due to a current that rapidly switches direction. The electromagnet is placed in a position where it experiences a constant magnetic field as a result of the presence of a permanent magnet. Like every magnet, the electromagnet and the permanent magnet interact with each other; opposite sides attract while like sides attract. This interaction generates a force, causing the alternating current to constantly reverse the poles of the electromagnet in an audio speaker to repeatedly switch directions.

Answer:
There are no additional components that can be added to the IPv4 protocol to improve its utility
Explanation:
The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.
This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.
So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.
Hope this helps!

See explaination
Explanation:
java code:
class DONALD
{
static class Node
{
int data;
Node next;
}
static Node head=null;
static int largestElement(Node head)
{
Int max=Integer.MIN_VALUE;
while(head!=null)
{
if(max<head.data)
max=head.data;
head=head.next;
}
return max;
}
static int smallestElement(Node head)
{
int min=Integer.MAX_VALUE;
while(head!=null)
{
if(min>head.data)
min=head.data;
head=head.next;
}
return min;
}
static void push(int data)
{
Node newNode=new Node();
newNode.data= data;
newNode.next=(head);
(head)=newNode;
}
static void printList(Node head)
{
while(head!=null)
{
System.out.println(head.data + " -> ");
head=head.next;
}
System.out.println("NULL");
}
public static void main(String[] args)
push(15);
push(14);
push(13);
push(22);
push(17);
System.out.println("Linked list is : ");
printList(head);
System.out.println("Maximum element in linked list: ");
System.out.println(largestelement(head));
System.out.print("Maximum element in Linked List: " );
System.out.print(smallestElement(head));
}
}
