The Nobel Prize for Literature was awarded to Samuel Beckett, an Irish playwright, novelist, and poet, in 1969. He received the prestigious award "for his writing, which—in new forms for the novel and drama—in the destitution of modern man acquires its elevation." Samuel Beckett's works, including his most famous play "Waiting for Godot," have had a significant impact on modern literature and theater.

Yen, Lira and Dollar are currency. Ounce is used for weight.

1st term = 12
2nd term = 12 + 20 = 32
3rd term = 32 + 40 = 72
4th term = 72 + 80 = 152

Thus, the missing term is 5th term = 152 + 160 = 312

The Education of children with special needs should be provided along with children with non-special needs. To promote the education of special needs children along with non-special needs children concept of inclusive education was proposed. In Inclusive Education, all students are welcomed, they have been given equal opportunity irrespective of caste, creed, religion, special-needs, non-special needs.
Hence, the correct answer is, 'Along with other normal children.'

Constructive interference occurs when the path differences (S₁​P−S₂​P) is an integral multiple of λ or (S₁​P−S₂​P)=nλ
Where n=0,1 ,2 3,….

Constantan is an alloy of copper (55%) and nickel (45%) where Manganin is an alloy of copper (84%) manganese(12%) and nickel (4%).
When all metals show increase in resistivity with increase in temperature and semiconductors show the reverse, Constantan and Manganin show a completely different property.
Their main feature is their low thermal variation of their resistivity, which is constant over a wide range of temperatures.
Metals, including alloys, have free electrons as charge carriers. Their movement controls by defects. One of defects of usual metal is oscillations of atoms due to temperature. More temperature - more oscillations - more collisions of electrons with atoms - less mobility - more resistivity. In alloys, like constantan and Manganin, atoms are in disorder. So they have big resistivity. Their additional disorder due to temperature increase is insignificant. That is why they have no temperature dependence on resistivity.
 

In accordance with Kirchhoff’s second law i.e. Kirchhoff’s voltage law (KVL), the algebraic sum of all the potential differences in a closed electric circuit or closed loop that contains one or more cells and resistors is always equal to zero.
This law is popularly called the law of conservation of voltage.
 

When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees.For any angle of incidence greater than the critical angle, light will undergo total internal reflection.

Plane. The shape of the wavefront in case of a light emerging out of a convex lens when a point source is placed at its focus is a parallel grid.

The images of clouds and trees in water are always less bright than in reality because only a portion of the incident light is reflected and quite a large portion goes mid water.

Given,

We have v=f x λ
3x108 m/s= 60000 Hz x λ
λ=5000m
λ=5km
Destructive interference.

A wave front is a line representing all parts of a wave that are in phase and an equal number of wavelengths from the source of the wave. A ray is a line extending outward from the source and representing the direction of propagation of the wave at any point along it. Rays are perpendicular to wave fronts.

The correct answer is option C
Conductivity of a solution is equal to the conductance of a solution of 1cm length and cross section area of 1 square cm it may also be defined as the conductance of one centimeter cube of the conductor .It is represented by the symbol kappa (k) mathematically we can write
K = G×G⋅ conductance ,G⋅=cell constant
The unit of K is ohm−1cm−1 or S cm−1
The conductivity K of an electrolytic solution depends on the concentration of the electrolyte nature of solvent and temperature .molar conductivity molar conductivity of a solution at a given concentration is the conductance of the volume v of solution containing one mole of electrolyte between two electrodes with area of cross section a and distance of unit length.

Given: Concentration of K⁺ inside the cell is 20 times higher than outside:

[K⁺]_inside / [K⁺]_outside = 20

2.303 RT / F = 59 mV (at room temperature)

Objective: Find the magnitude of potential difference (E) across the cell membrane due to this ion concentration difference.

Relevant formula: Nernst Equation For a monovalent ion like K⁺:

E = (2.303 RT / zF) log₁₀ ([K⁺]_outside / [K⁺]_inside)

where:

• E = membrane potential (in volts or millivolts)
• z = +1 (charge of K⁺)
• R = gas constant
• T = absolute temperature
• F = Faraday constant
• [K⁺]_outside, [K⁺]_inside = concentrations outside and inside respectively

Step 1: Substitute values E = 59 mV × log₁₀ (1/20) = 59 × log₁₀ (0.05)

Step 2: Calculate logarithm log₁₀ (0.05) = log₁₀ (1/20) = -log₁₀ (20) ≈ -1.3010

Step 3: Calculate E E = 59 × (-1.3010) = -76.76 mV

Step 4: Interpret result The negative sign indicates that the inside is negative relative to the outside (typical for K⁺ potential).

The magnitude of potential difference is:

|E| = 76.76 mV

Final answer: 76.8 mV (approx)

Isoelectronic species means species having same number of electrons.
In CO; no. of electrons = 6 + 8 = 14
In N₂; no. of electrons = 7 + 7 = 14

C = 84/12 = 7 mole

H₂ = 12 g = 6 mole

O₂ = 56/22.4 = 5/2 mole

12C + 11H₂ + 11/2 O₂ → C₁₂H₂₂O₁₁

L.R. = O₂

11/2 mole O2 produce 1 mole sucrose 5/2 mole O2 will for 5/11 mole sucrose mass of sucrose = 5/11 × (mol. mass)

= 5/11 × 342

= 155.45 g

A number with terminal decimal expansions have the denominator  in the form,
2^m 5ⁿ where m & n ∈ W.
The number 
Which the denominator is in the form,
 with m = 2 , n = 3.
Hence, it has terminal decimal expansion.

The correlation between x and y is positive correlation because it is a correlation where if one variable increases, the other also increases, and if one variable decreases, the other also decreases.

Here the objective function is given by : F = 4x +6y .

Maximum of F – Minimum of F = 72 – 12 = 30 .

Since x is the square of y in relation R.
i.e. option D is correct.

A point C in the domain of a function f at which either f(c) = 0 or f is not differentiable.  
The point f  is called the critical point.
c is called the point of local maxima
If f ′(x) changes sign from positive to negative as x increases through c, that is, if f ′(x) > 0 at every point sufficiently close to and to the left of c, and f ′(x) < 0 at every point sufficiently close to and to the right of c.
c is called the point of local minima
If f ′(x) changes sign from negative to positive as x increases through c, that is, if f ′(x) < 0 at every point sufficiently close to and to the left of c, and f ′(x) > 0 at every point sufficiently close to and to the right of c.
c is called the point of inflexion
If f ′(x) does not change sign as x increases through c, then c is neither a point of local maxima nor a point of local minima.

6 × side² = 3750
Side² = 625
Sice = 25 cm
So the answer = 25 × 25 × 25 = 15,625 cm3
Hence, Option D is correct.

2 × (5x + 3x) = 64
8x = 32
x = 4
