Enthalpy Changes the overall energy change in the substance portrayed in the graph at 48°C.
What are the data that were obtained from the question?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
Collect like terms
1254T2 = 35 + 25.08
1.254T2 = 60.08
Divide both side by the coefficient of T2 i.e 1.254
T2 = 60.08/1.254
T2 = 47.9 ≈ 48°C
Therefore, the final temperature of the water is 48°C.

A disk input/output (i/o) operation is a much slower process than accessing information stored in main memory, sometimes by as much as three or four orders of magnitude. (True)
What is main memory?Internal physical memory of the computer is referred to as main memory. Main memory, in more precise terms, is the short-term memory of a computer. The main memory's function is to store information that the CPU frequently needs to access, such as instructions and data that is being processed right now. Data stored in secondary storage devices, such as hard drives, can be accessed much more quickly.
An instruction fetch unit reads instructions into the CPU, decodes them, and then the CPU executes them using one or more execution units. Only information that is present in the computer's main memory can be changed. Each program you run and each file you access must therefore be copied from a storage device into the main memory space.

XSS is an attack that injects malicious scripts into web pages to redirect users to fake websites to gather personal information.
What is XSS?Malicious scripts are injected into websites that are otherwise safe and reputable in Cross-Site Scripting (XSS) attacks. XSS attacks take place when a web application is used by an attacker to send malicious code, typically in the form of a browser side script, to a different end user.
Wherever a web application incorporates user input into the output it produces without validating or encoding it, flaws that enable these attacks to succeed can be found.
An attacker may send a malicious script to an unwary user using XSS. The end user's browser will run the script regardless of whether it should be trusted because it has no way of knowing.

if "Cindy" in friends: #to check if the element is on the list
print("She is a friend")
# What if i want to know the index of Cindy? In that case do this....
print()
cindy_sIndex = friends.index("Cindy")
cindy_sIndex2 = friends.index("Cindy", cindy_sIndex + 1) # searches for other instances of Cindy
print(cindy_sIndex)
print(cindy_sIndex2)
When it searches for another Cindy, why is there + 1 (-3 line of code)
Answer:
The +1 after cindy_sIndex in the line cindy_sIndex2 = friends.index("Cindy", cindy_sIndex + 1) specifies the starting position for the search for the second occurrence of "Cindy" in the list. This is useful if you want to find all occurrences of an element in a list and you only want to find matches that occur after the previous one.
For example, if the list is ["Harry", "Cindy", "Jack", "Mason", "Cindy"] and you want to find the index of both occurrences of "Cindy", you can use the index method in a loop and specify a starting position for the search each time. The first time you call the index method, you start the search at the beginning of the list (at index 0). The second time you call the index method, you start the search after the index of the previous match, which is 1 (the index of the first occurrence of "Cindy"). This means that the search will start at index 2 and will find the second occurrence of "Cindy" at index 4.
Here is some example code that demonstrates how this works:
friends = ["Harry", "Cindy", "Jack", "Mason", "Cindy"]
# Find the first occurrence of "Cindy"
cindy_sIndex = friends.index("Cindy")
print(cindy_sIndex) # Output: 1
# Find the second occurrence of "Cindy"
cindy_sIndex2 = friends.index("Cindy", cindy_sIndex + 1)
print(cindy_sIndex2) # Output: 4

In general, routing is carried out over a wide range of network types, including circuit-switched networks like the public switched telephone network (PSTN) and computer networks like the Internet. Routing is the higher-level decision-making process used in packet switching networks to direct network packets from their source to their destination through intermediary network nodes using certain packet forwarding techniques. The movement of network packets from one network interface to another is known as packet forwarding. Switches, routers, gateways, firewalls, and other types of network infrastructure generally serve as intermediate nodes.

Jason is attending the CompTIA Partner's Summit convention this year. While at the conference, Jason will need to ensure his smartphone has enough battery power to last the entire day without having to recharge it since it is hard to find an available electrical outlet in the conference rooms. Jason needs to ensure his smartphone is always available for use in order to receive updates from his team back home, as well. Which of the following would you recommend Jason use to ensure he can use the phone all day without his smartphone running out of power?
O Use a wireless charging pad
O Bring a power strip so that more than one person can use an electrical wall outlet
O Set the smartphone to airplane mode
O Use a smartphone case with a built-in battery
I would recommend Jason to; Use a smartphone case with a built-in battery. This is to ensure that he uses his phone all day without the smartphone running out of power.
Using a smartphone case with a built-in battery will allow Jason to extend the battery life of his smartphone without having to find an available electrical outlet to charge while at the conference.
Alternatively to the above correct choice, Jason could also use a portable charger or power bank to keep his smartphone charged.
Setting the smartphone to airplane mode would help to extend the battery life, but it will not be practical for Jason since he needs to receive updates from his team. Being on airplane mode will make his stay offline and unavailable for his team.
Using a wireless charging pad or bringing a power strip would not directly help to extend the battery life of Jason's smartphone.
