The correct answer is 'SPQR'.

Key Points

• Sentence S is the subject of the passage, thus it must be the first sentence.
• Sentence P, stating that a page can have multiple lines, builds on the concept introduced by S and hence should come second.
• Sentence Q follows suit, logically expanding the topic towards a page being a better measure of length of a book.
• Sentence R, which says "This is with respect to a line.", serves as a fitting conclusion, bringing the focus back to 'lines' from the discussion of 'pages'
• In this sequence, S introduces the concept of differentiating between a line and a page. P then dwells into the composition of how a page can have multiple lines. Q expands on the importance of a page as a measure of length of a book. Finally, R concludes the discussion by returning to the topic of a line.
• Hence, the correct answer is Option 1 "SPQR".

Shortcut Trick

Area of square = 44 × 44

Area of rectangle = 121 × Width

Width = (44 × 44) ÷ 121

Width = (4 × 11 × 4 × 11) ÷ (11 × 11) = 4 × 4 = 16 m

∴ The correct option is D.

Alternate Method

Given:

Length of rectangle (L) = 121 m

Side of square (a) = 44 m

Formula Used:

Area of rectangle = Length × Width

Area of square = Side²

Square Side = 44 m

Rectangle Length = 121 m W Area of Rectangle = Area of Square

Calculations:

⇒ Area of square = 44 × 44 = 1936 m²

⇒ Area of rectangle = Area of square

⇒ 121 × Width = 1936

⇒ Width = 1936 ÷ 121

⇒ Width = 16 m

∴ The correct option is D.

Additional Information

Perimeter and Diagonal Formulas

Perimeter of rectangle = 2 × (Length + Width) and Diagonal = √(Length² + Width²).

Square Properties

Perimeter of square = 4 × Side and Diagonal = Side × √2.

Area Conversion

To find a missing dimension when areas are equal, equate the products and solve: L₁ × W₁ = L₂ × W₂.

The correct answer is option 2, i.e., Parallel to the principal axis.

• A ray of light appearing to meet at the principal focus of a concave lens emerge after refraction will be parallel to the principal axis.
• In the case of a convex lens, the ray passing through the principal focus after refraction becomes parallel to the principal axis.

 

 

The correct answer is 746 watts.

Key Points

• Horsepower: Horsepower is a popular imperial unit of power of an engine. It is defined as the work done by a person or machine per unit amount of time.
• The term Horsepower was invented by James Watt.
• It is a unit of power that compares the power of a machine to the muscle power of the horse.
• In earlier days it was used to measure steam engine power output compared to the power of draft horses. But later on, its usage was expanded to different types of piston engines, electric motors, turbines, and other machinery.
• One mechanical horsepower of 550 foot-pounds per second is equivalent to 745.7 watts.

⇒ 1 Hp = 550 Foot pounds per second

⇒ 1 Pound = 4044822 Newtons

⇒ 1 Foot = 0.3048 meters

⇒ 1 Hp = 550 × 4.44822 × 0.3048 meters

⇒ 1Hp = 745.69 newton meter per second = 746 watt

The correct answer is (C, A, D, B).

 Key Points

• The sentence should start with the subject, which is "he" in this case.
• So, the first part is C.
• The next part should be the verb + preposition, which is "complains about all his."
• So, the next part is A.
• Then, we need to add the object, which is "about all his neighbours and the noise they make."
• So, the next pair must be DB.
• The correct answer is option 2.

Correct sentence: H**e constantly complains about all his neighbours and the noise they make.

Additional Information

• Option 1 (B, A, D, C) is incorrect because it starts with the object instead of the subject.
• Option 3 (B, D, A, C) is incorrect because it starts with the object and also places the subject after the object.
• Option 4 (D, B, C, A) is incorrect because it starts with the object and places the subject after the verb.

Given:

2 [(54 × 17 × 54 × 17) ÷ $(2(\sqrt{289\div 2}))^2$ ]

Concept used:

Calculation:

2 [(54 × 17 × 54 × 17) ÷ $(2(\sqrt{289\div 2}))^2$ ]

⇒ 2[54 × 17 × 54 × 17) ÷ $(2× \frac{17}{\sqrt2})^2$ ]

⇒ 2[54 × 17 × 54 × 17) ÷ $(\sqrt2 × 17)^2$ ]

⇒ 2[54 × 17 × 54 × 17) ÷ 2 × 17 × 17]

⇒ 54 × 54

⇒ 2916

∴ Option 2 is the correct answer.

The correct answer is Joule.

Key Points

• Heat
• It is a form of energy that flows from one body to another due to the difference in temperature between the bodies.
• It is simply the potential energy stored in the bonds that hold particles within the object together.
• Heat or thermal energy is the form this energy possesses when it is transferred between systems and surroundings.
• SI unit of energy is Joule (J) and from above it is clear that heat is a form of energy.
• Therefore the SI unit of heat energy is Joule (J).
