Enthalpy Changes the overall energy change in the substance portrayed in the graph at  48°C.

Mass (m) = 0.3 Kg

Initial temperature (T1) = 20°C

Heat (Q) added = 35 KJ

Specific heat capacity (C) = 4.18 KJ/Kg°C

Final temperature (T2)

The final temperature of water can be obtained as follow:

Q = MC(T2 – T1)

35 = 0.3 x 4.18 (T2 – 20)

35 = 1.254 (T2 – 20)

Clear the bracket

35 = 1.254T2 – 25.08

C) Asymmetric-key encryption uses a public key and a private key to allow users to communicate securely.

What is Asymmetric-key encryption?

A public key and a private key, which are connected mathematically, are used in asymmetric encryption for encryption and decryption. The associated private key is used for decryption if the public key is utilised for encryption. The associated public key is used for decryption if the private key is employed for encryption.

Asymmetric-key encryption, also known as public-key encryption, uses a public key and a private key to allow users to communicate securely.

In asymmetric-key encryption, each user has a pair of keys: a public key and a private key. The public key is used to encrypt messages that are sent to the user, and the private key is used to decrypt those messages. The private key is kept secret by the user, while the public key is shared with others.

To send a secure message to another user, the sender uses the recipient's public key to encrypt the message. The recipient can then use their private key to decrypt the message. Because the private key is kept secret, only the intended recipient is able to decrypt the message, ensuring that the communication is secure.

# Get the input from the user

userText = input()

fourthChar = input()

# Replace the fourth character of the string with the new character

userText = userText[:3] + fourthChar + userText[4:]

# Print the modified string

print(userText)

Explanation:

This code first gets the input from the user and stores it in the userText and fourthChar variables. It then uses string slicing to replace the fourth character of the string with the new character. Finally, it prints the modified string.

The input string is cheetah, and the fourth character is e. The code replaces this character with the new character v, resulting in the modified string chevtah.

IPv4 uses 32-bit addresses and can support a maximum of approximately 4.3 billion unique addresses. In contrast, IPv6 uses 128-bit addresses and can support a virtually unlimited number of unique addresses.

Therefore, This is important because the rapid growth of the internet and the increasing number of devices that are connected to it have led to a shortage of available IPv4 addresses. As a result, IPv6 was developed to address this shortage and provide a much larger pool of available addresses.

Answer:

It is generally a good practice to follow a specific order when connecting cables to a network switch. This helps to maintain a logical and organized layout for the cables, which makes it easier to identify and troubleshoot any issues that may arise.

One way to organize the cables on a network switch is to start with the network endpoints (such as computers, printers, and other devices) on the first few ports and work your way up. This allows you to easily locate and access the endpoints when needed.

For trunk lines (such as those connecting the switch to other switches or routers), it is generally recommended to start from the last few ports and work your way backwards. This helps to keep the trunk lines separate from the endpoint cables, which can make it easier to identify and troubleshoot any issues that may arise.

It is important to note that these are general guidelines and may vary depending on the specific requirements and needs of your network. It is always best to consult with your organization's IT department or guidelines to determine the best practices for cable management on your network.

What is loop ?

A loop is a set of instructions that are repeatedly carried out until a specific condition is met in computer programming. In most cases, a given procedure, such as collecting data and modifying it, is followed by a condition check, such as determining whether a counter has reached a predetermined number.

(int p = 1; p < data.length - 1; p++) can replace /* missing loop header */ so the method countPeaks works as intended.

This loop header will start the loop at the second element of the array (index 1) and end the loop at the second-to-last element of the array (index data.length - 2). This is because we don't want to check the first or last element of the array for local maximum values, as they have only a single adjacent element.

The other options are not suitable because they either start the loop at the wrong position (options a and e), end the loop at the wrong position (options a and d), or use the incorrect spelling of "length" (options c). Option c is the only one that starts the loop at the second element of the array and ends the loop at the second-to-last element of the array, making it the correct choice.
