Microsoft and OpenAI are jointly embarking on a $100 billion project to create “Stargate,” an AI supercomputer. Scheduled for launch in 2028, it follows OpenAI’s AI upgrade in 2022. The project aims to surpass existing data centers’ capabilities by 100 times. Divided into five phases, with Stargate as the fifth, a smaller fourth-phase supercomputer is slated for release in 2026. Significant costs will be allocated to acquiring essential AI chips.

Checking Statement I:

Here, as Kirti correctly remembers that her birthday is in the second half of the year, so her birthday is in July or August or September or October or November or December.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Here, as Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December, so we can say that Kirti’s birthday is in November.

Hence data in statement II is sufficient to answer the question.

Hence, Option B is correct.

URL is the name for a web page address.

1. URL stands for Uniform Resource Locator.
2. Every web page that is displayed on the Internet has a specific address associated with it. This address is known as the URL. It tells us the location of the web page being displayed and other related information.
3. As the postal address is required to reach a letter to a person staying anywhere on earth, a unique location (address) of a web element which may be a website or a web page is required in the World Wide Web to view it in the browser. This unique address of the web elements is referred to as a URL.
4. The URL consists of four basic parts, namely, server type, hostname, the folder name, and the filename. Each one of these has a specific function.
5. The “server type” indicates the type of Internet server (Protocol) being accessed. The server type is always followed by “://” and the hostname.
6. The hostname is the Internet address of a remote computer on which the files reside.
7. The folder name indicates the name of the directory in which the files are located.
8. The filename specifies the name of the specific document to be displayed in the browser. The filename itself consists of two pieces of information, the name of the file to be displayed and the file extension, which specifies the file type (.htm for HTML file, .txt for a text file, .bmp for a bitmap image, etc.) 
9. The structure of a URL can be represented as follows: Server type://Hostname/directory/sub-directory/.../filename
10. Example Of URL: www.testbook.com

Thus, option 4 is the correct answer.

 Additional Information

Directory: 

• A web directory or link directory is an online list or catalog of websites.
• That is, it is a directory on the World Wide Web of (all or part of) the World Wide Web.
• Historically, directories typically listed entries on people or businesses, and their contact information; such directories are still in use today.
• A web directory includes entries about websites, including links to those websites, organized into categories and subcategories.
• Besides a link, each entry may include the title of the website and a description of its contents. In most web directories, the entries are about whole websites, rather than individual pages within them (called "deep links"). Websites are often limited to inclusion in only a few categories.

Folder:

•  A digital folder has the same purpose as a physical folder – to store documents.
• Computer folders can also store other types of files, such as applications, archives, scripts, and libraries. Folders can even store other folders, which may contain additional files and folders. Folders are designed for organizing files.
• For example, you might store your digital photos in a "Pictures" folder, your audio files in a "Music" folder, and your word processing documents in a "Documents" folder.

Domain: 

• A domain contains a group of computers that can be accessed and administered with a common set of rules.
• For example, a company may require all local computers to be networked within the same domain so that each computer can be seen from other computers within the domain or located from a central server.
• Setting up a domain may also block outside traffic from accessing computers within the network, which adds an extra level of security.

The correct option is (2)

Concept:-

Bytes:- Bytes are the best units of data on an external storage device.

Key Points

• A byte is an eight-binary digit long unit of data in the majority of computer systems. Most computers utilize bytes to represent characters like letters, numbers, and typographic symbols.
• Although they frequently offer instructions that can test and modify bits, computers are typically built to store data in units called bytes, which are multiples of bits.
• In a computer, the smallest unit of data is called a bit (short for binary digit). One of the binary values, 0, or 1, represents a bit.
• An external storage device, also known as auxiliary storage or secondary storage, is a container for all addressable data storage outside of the main storage or memory of a computer.
• Pen drives, CDs, and DVDs are a few examples of external storage devices. A pen drive is a tiny, independently powered device that attaches to a computer via a USB connector.​

If the car does half the journey @ 30 kmph and the other half at 40 kmph it’s average speed can be
estimated using weighted averages.
Since, the distance traveled in each part of the journey is equal, the ratio of time for which the car
would travel would be inverse to the ratio of speeds. Since, the speed ratio is 3:4, the time ratio
for the two halves of the journey would be 4:3. The average speed of the car would be:
(30 × 4 + 40 × 3)/7 = 240/7 kmph.
It is further known that the car traveled for 17.5 hours (which is also equal to 35/2 hours).
Thus, total distance = average speed × total time = (240 × 35)/(2 × 7) = 120 × 5 = 600 km

If we apply source transformation between the 6-ohm resistor and the 1 A source, we get a 6 V source in series with a 6-ohm resistor. Now we have two meshes. Let us consider

I₁ flowing in the first mesh and I₂ flowing in the second mesh.

The mesh equations are:

9I₁ - 6I₂ = 4

-6I₁ + 16I₂ = 6

Multiplying the first equation by 6, the second equation by 9 and adding them,

54I₁ - 36I₂ - 54I₁ + 144I₂ = 24 + 54

108I₂ = 78

I₂ = 13/18

I₂ = 0.72 A

The short circuit current is 0.72 A

Hence, the correct option is (A).

An over-excited 3-phase synchronous motor is not only used as a motor to supply the needed mechanical power but also acts as a power factor correction device.But generally prefered for power factor correction.

Gross mechanical power output = shaft power + mechanical losses

= 4.1×103+750

= 4850

Here slip =

Slip s =

= 0.03

Rotor copper loss =

= 150W

Hence, the correct option is (B).

B.O.T_unit = Board of trade unit

Number of circuits = Number of sources

P = √3 V_lI_L
V_lI_L= 20/√3
Pf is lagging,
So, P₁ = V_LI_Lcos(30-ϕ)
= 20/√3×cos(30-30) = 20/√3
P₁ = V_LI_Lcos(30-ϕ)
= 20/√3×cos(30-30)
= 10/√3
