The correct solution is 'anybody'.

Key Points

• A determiner is a word that is used to modify or introduce the noun in a sentence. It mostly acts like an adjective in that it refers to the noun.
• In the sentence given in the question, the subject of the entence is 'You' and the object of the sentence which is also a noun is 'want'.
• Since the noun 'want' in the sentence indicates 'people to be invited to the birthday', the most appropriate word would be 'anybody'.
  • Option 1, 'anywhere' is incorrect as it is not appropriate to refer to a person.
  • Option 3, 'something' is also incorrect as it is also inapprpriate to use it to refer to a person.
  • Option 4, 'anything' is an incorrect option as it is used to refer to an object not a person.
• Hence the corret answer is Option 2.

The correct answer is 'to burst'.

Key Points

• Non-finite verbs do not work as the actual verbs in the formation of the sentence.
• They have the forms of verbs but they do not work as them.
• They work as adjectives, gerunds, and adverbs in the sentence.
  • ​​E.g.- The plane is all set to take off.
  • Running is good for health.

​Hence, the correct answer is 'to burst'.

The correct answer is "spiteful"

Key Points

• The correct option is 3.
  • The sentence is describing someone who has a "wanton disregard" for the facts. Wanton means without restraint or control, and disregard means to pay no attention to something. Together, this phrase is describing someone who is not considering or caring about the facts in a situation. (प्रचंड का अर्थ है संयम या नियंत्रण के बिना, और अवहेलना का अर्थ है किसी चीज़ पर ध्यान न देना। साथ में, यह वाक्यांश किसी ऐसे व्यक्ति का वर्णन कर रहा है जो किसी स्थिति में तथ्यों पर विचार या परवाह नहीं कर रहा है।)
    • Example: Rampant spread of those wanton in the night.
  • Spiteful is the closest in meaning to this phrase because it implies a negative attitude towards something or someone, which is similar to the idea of not caring about the facts. A spiteful person would likely disregard facts that do not align with their own beliefs or opinions. (इसका तात्पर्य किसी चीज़ या किसी व्यक्ति के प्रति नकारात्मक दृष्टिकोण से है, जो तथ्यों की परवाह न करने के विचार के समान है। एक द्वेषी व्यक्ति उन तथ्यों की अवहेलना कर सकता है जो उसकी अपनी मान्यताओं या विचारों से मेल नहीं खाते।)
    • Example: The politician's spiteful rhetoric was aimed at discrediting his opponents, regardless of the facts.

Hence, the correct answer is "spiteful"

The universal law of gravitation:

• Sir Isaac Newton put forward the universal law of gravitation in 1687 and used it to explain the observed motions of the planets and moons.
• Law states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

• Formula, Gravitational force, , where, F is the gravitational force between bodies, m_1, and m₂ are the masses of the bodies, d is the distance between the centers of two bodies, and G is the universal gravitational constant.
• Here, universal gravitational constant, G = 6.67 × 10^-11 Nm/kg²
• The Universal Gravitational Law can explain almost anything, right from how an apple falls from a tree to why the moon revolves around the earth.

Explanation:

Gravitational force,

• Force is directly proportional to the product of the masses.
• And inversely proportional to the square of the distance between them.
• Hence, both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Concept:

Self-Induction

• Whenever the electric current passing through a coil changes, the magnetic flux linked with it will also change.
• As a result of this, in accordance with Faraday’s laws of electromagnetic induction, an emf is induced in the coil which opposes the change that causes it.
• This phenomenon is called ‘self-induction’ and the emf induced is called back emf, current so produced in the coil is called induced current.

Induced e.m.f can be given as:

​ -----(1)

Where VL = induced voltage in volts, L = self-inductance of the coil,  rate of change of current in ampere/second.

Calculation:

Given:

I1 = +2 Amp, I2 = -2 Amp, dt = 0.05 sec, VL = 8 volt

⇒ dI = I2 - I1 = (-2 - 2) = -4 Amp

From equation 1,

Concept:

• According to Pascal’s Law, the pressure or intensity of pressure at a point in a static fluid is equal in all directions.
• For a plane surface of arbitrary shape immersed in a liquid in such a way that the plane of the surface makes an angle θ with the free surface of the liquid:

A = Total area of an inclined surface, h̅ = Depth of center of gravity of inclined area from a free surface, h* = Distance of center of pressure from the free surface of a liquid

Calculation:

Width = b = 4m, depth = d = 6m, angle of inclination = θ = 30 ° , Distance from free surface = 3 m

From the diagram above, we can see that

Vertical distance of CG from the top plate (x)

Sin θ =

 =

x = 1.5 m

Concept:

Zener Diode:

• A Zener diode not only allows current to flow from the anode to the cathode but also, in the reverse direction on reaching the Zener voltage.
• Due to this functionality, Zener diodes are the most commonly used semiconductor diodes.
• It is a heavily doped semiconductor device that is designed to operate in the reverse direction.

​There are two types of breakdowns for a Zener Diode

• Avalanche Breakdown in Zener diode:
  • ​Avalanche breakdown occurs in the normal diode and Zener Diode at high reverse voltage.
  • When a high value of reverse voltage is applied to the PN junction, the free electrons gain sufficient energy and accelerate at high velocities.
• Zener Breakdown in Zener diode:
  • ​When the applied reverse bias voltage reaches closer to the Zener voltage, the electric field in the depletion region gets strong enough to pull electrons from their valence band.
  • The valence electrons that gain sufficient energy from the strong electric field of the depletion region break free from the parent atom. At the Zener breakdown region, a small increase in the voltage results in the rapid increase of the electric current.

Symbol and VI characteristic:

Explanation:

The Zener diode is a heavily doped PN junction and is connected in reverse biased in the circuit.

Calculation:

Given A = {1, 3, 5, 7, 9, 11, 13, 15, 17} B = {2, 4, ... , 18}.

N is the set of natural numbers and is the universal set.

∴ A^' = {2, 4, 6, 8,....18, 19 , 20, 21...}

B' = {1, 3, 5, 7, .... 19, 20, 21....}

A ∪ B = {1, 2, 3, 4, ... 18}

(A ∪ B) ∩ B′ = {1, 3, 5, 7,... 17}

Now A' ∪ [(A ∪ B) ∩ B′]

= {2, 4, 6, 8,....18, 19 , 20, 21...} ∪ {1, 3, 5, 7, 9, 11, 13, 15, 17}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, .....}= N
