One reason for using an alias is simplicity. T/F
Answers
True. One reason for using an alias is simplicity. An alias is a shorthand or alternate name that can be used to refer to a database object such as a table or column.
Using an alias can simplify the syntax of a SQL statement and make it easier to read and understand.
For example, instead of writing a long and complex SQL statement that references multiple tables and columns, an alias can be used to give each object a shorter and more manageable name. This can make the statement more concise and easier to read, as well as reducing the risk of errors or confusion when working with large and complex queries.
In addition to simplicity, aliases can also provide other benefits such as improved security, as they can be used to hide sensitive information or protect the names of tables and columns from being exposed to unauthorized users.

22.5 s is the correct answer to the given question .
Explanation:

\(d=7.5km=7.5\times 10^3 m\)
For light:
We know that speed of light c

We know that
\(Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms\)
For thunder :
Speed of sound ,v=332 m/s
\(Time\ taken\ by\ sound \\t\’=\dfrac{7500}{332}=22.59 s\)

newList = listOne + list Two
new List = extend(listOne, list Two)
newList = listOne.extend(list Two)
newList.extend(listOne, list Two)
Answers
To add 2 list ---> newList = listOne + listTwo
This will create a new list by concatenating the elements of listOne and listTwo. The resulting list will be:
newList = ['a', 'b', 'c', 'd', 'e', 'f', 's']
The other options are incorrect:
new List = extend(listOne, list Two) is incorrect because extend() is a method of list objects, not a built-in function, and it should be called on a list object. Also, the correct syntax to call extend() is listOne.extend(listTwo).
newList = listOne.extend(listTwo) is incorrect because extend() modifies the list in-place and returns None, so newList will be None.
newList.extend(listOne, listTwo) is incorrect because extend() takes only one argument, which should be an iterable. To extend a list with the elements of another list, you should call extend() with that list as the argument, like newList.extend(listTwo).

You receive an email from your school's head of IT. There is a concern for a potential hack to the school's servers. IT knows some accounts have been compromised, with their login and passwords overwritten by the hackers. They need to reset the accounts that the hackers have changed the passwords on. However, they don't have access to the passwords directly, and the change records were corrupted by the attack. They need students and staff to confirm their passwords by logging into a secure site. If the login fails, they'll know your account was compromised and reset your account immediately.
a.) This could be a phishing attempt. If the situation is as described in the email, this is also serious, but the method suggested is the same methods used by social hackers. Look up your IT Departments phone number and call them about the email.
b.) This is a serious issue, and the email came from the head of IT. The site also shows that it's secure. The longer it takes to reset accounts, the longer the hackers will have access to your account. Follow the instructions in the email from the head of IT.
