x = 420
Hence, Option C is correct. 

Explanation:
The application of the internet refers to the various ways in which the internet is used in our daily lives. The internet has revolutionized the way we communicate, conduct business, and access information. However, there are certain activities that are not considered as applications of the internet.
Here, the option "D: Sleeping" is not an application of the internet. Sleeping is a biological process and does not involve the use of the internet. The internet cannot be directly used for sleeping purposes.
Applications of the Internet:
A: Communication
- The internet allows people to communicate with each other through various means such as email, instant messaging, video calls, and social media platforms.
- It enables people to connect with others globally, facilitating communication in real-time.
B: Banking
- The internet is widely used for online banking services, allowing individuals to access their bank accounts, make transactions, and manage their finances online.
- It provides convenience and accessibility to banking services from anywhere at any time.
C: Shopping
- Online shopping has become increasingly popular with the advent of the internet.
- It allows consumers to browse and purchase products from various online retailers, making shopping more convenient and accessible.
In summary:
The internet has numerous applications, including communication, banking, and shopping. However, sleeping is not an application of the internet as it does not involve the use of online services or activities.

The given sentence is already in the passive voice: "You will be looked after well."

The sentence implies that someone (not specified in the sentence) will take care of you properly. Among the options provided:

Option C: "They will look after you well."
This option fits the context as it conveys a similar meaning in the active voice, indicating that someone ("they") will take care of you well. Therefore, the correct answer is indeed option C.

Answer: A: A secret enemy Explanation: The idiom "a snake in the grass" refers to someone who appears to be trustworthy and friendly but turns out to be deceitful or harmful. In this context, the minister was trusted by others, but he proved to be a secret enemy during the revolution. - A secret enemy: Someone who pretends to be trustworthy and friendly but is actually deceitful or harmful. - A treacherous person: Although this option is closely related to the meaning of the idiom, it does not capture the aspect of being a secret enemy, which is the primary focus of the idiom. - An unforeseen danger: This option does not directly relate to the meaning of the idiom, which focuses on a person's deceptive nature rather than an abstract danger. - An unexpected misfortune: This option also does not directly relate to the meaning of the idiom, as it refers to an unfortunate event rather than a person's deceitful nature.

Ohm’s law states I is proportional to V.This holds good at steady temperatures and for the flow of constant current.

The Particle Model of emission and absorption is based on the idea that light is composed of discrete particles called photons, and these photons carry quantized energy. This model helps us understand how atoms and molecules interact with light by either emitting or absorbing photons during electronic transitions.

The long straight wire and side AB  carry current in the same direction, hence will attract each other.
The long straight wire and side CD carry current in the opposite direction, hence will repel each other.
Force on side BC  will be equal and opposite to force on side DA.
Since CD  is farther from the wire than AB,  the force of attraction on  AB  will exceed the force of repulsion on CD.
Hence, there will be a net force of attraction on the loop ABCD and it will move towards the wire.

Long distance radio broadcasts use short-wave bands because they can be reflected by the ionosphere of the earth's atmosphere and thus can be send to longer distances.

Infra red rays are basically heat radiation that gives warmth which support the plant growth. It also helps in treating muscle pain in the same way we use hot water massage for muscle cramps.

 Suppose the angle between the transmission axes of the analyser and the polarizer is θ. The completely plane polarized light form the polarizer is incident on the analyser. If E₀ is the amplitude of the electric vector transmitted by the polarizer, then intensity I₀ of the light incident on the analyser is
I ∞ E₀²
 
The electric field vector E₀ can be resolved into two rectangular components i.e E₀ cosθ and E₀ sinθ. The analyzer will transmit only the component ( i.e E₀ cosθ ) which is parallel to its transmission axis. However, the component E₀sinθ will be absorbed by the analyser. Therefore, the intensity I of light transmitted by the analyzer is,
 
I ∞ ( E₀ x cosθ )²
 
I / I₀ = ( E₀ x cosθ )² / E₀² = cos2θ
 
I = I₀ x cos²θ
when light passes from polarizer it's intensity becomes half and when passed through analyser it becomes,
I = I₀ x cos²θ/2
 

We know that for two coherent sources, the intensity of their maxima is (I_max +  I_min)² and that of its minima is (I_max +  I_min)² . Thus we get the intensity of maxima = 121k and that of minima = 9k, for some constant k as (I_max = 100k and  I_min = k.
Thus we get the ratio as 121:81.

Magnification for convex lens,

Here, f = 10cm = 10 × 10⁻² m, u = 1.5 × 10¹¹ m

∴  Diameter of the image,

Their placements in ECS is in order Y > Z > X.
Thus, reducing nature is also in same order y > Z > X

In anomalous Zeeman effect the splitting of spectral lines occurs due to interaction of the applied magnetic field with the magnetic moment generated by the orbital and 'spin' motions of the electron.

The correct answer is Option B.

Λ_m of AB = 145.05 cm²mol^-1
Λ_m of AB = Λ^oA + Λ^oB (Kohlraush’s law)
      145    = Λ^oA + Λ^oB --- (1)

 Λ_m of CB = 110.10 Scm²mol^-1

 Λ_m of CB = Λ^oC + Λ^oB 
    110.1    =  Λ^oC + Λ^oB --- (2)

Eqn (1) - Eqn (2)
 
145 - 110.1 = Λ^oA + Λ^oB - Λ^oC + Λ^oB
34.9 = Λ^oA - Λ^oC
34.9 = 73.5 - Λ^oC
Λ^oC = 73.5 - 34.9 
       = 38.6 Scm²mol^-1

 ∫ex[tan x + log sec x] dx

Required area :

Let S = {Persons who drive scooter}
C = {Persons who drive car}
Given, n(S ∪ C) = 80, n(S) = 35, n(C) = 60
Therefore, n(S ∪ C) = n(S) + n(C) - n(S ∩ C)
80 = 35 + 60 - n(S ∩ C)
80 = 95 - n(S ∩ C)
Therefore, n(S ∩ C) = 95 – 80 = 15
Therefore, 15 persons drive both
scooter and car.
Therefore, the number of persons who
drive a scooter only = n(S) - n(S ∩ C)
= 35 – 15
= 20
Also, the number of persons who drive car only = n(C) - n(S ∩ C)
= 60 - 15
= 45
