Understanding the Problem
In a Young's double slit experiment, the introduction of a transparent sheet in front of one slit alters the path length of the light waves, resulting in a shift of the interference fringes.
Given Data
- Wavelength of light, λ = 4800 Å = 4800 x 10^-10 m
- Number of fringes shifted, N = 30
- Refractive index of the sheet, n = 1.6

Nipun Tuteja answered |
Sum of the numbers (S) formed by taking all the given n digits is-
S=(sum of all digits)×(n−1)!×(111....n times)
Now according to the question, the digits are 1,3,5,7
∴n = 4
Sum of digits = 1+3+5+7 = 16
∴S = 16×3!×1111
Hence the correct answer is (C) 16×3!×1111.

EduRev Humanities answered |
Force vector follows the principle of superposition which says all the force vectors can be vectorially added if applied on one point to get the net force vector. Hence we get
F = F1 + F2 + F3
= (-2 + 3) i + (1 - 2) j
F = i - j = ma
Thus we get a = (i - j) /m
= (i - j) / 2
F = F1 + F2 + F3
= (-2 + 3) i + (1 - 2) j
F = i - j = ma
Thus we get a = (i - j) /m
= (i - j) / 2

- Justice G. Rohini Committee was set up to examine the possibility of creating categories within OBCs for the reservation to ensure “equitable distribution” of representation among all OBC communities. Its objectives include working out a mechanism, criteria, norm and parameters through a scientific approach for sub-categorisation within the OBCs and identifying the respective castes or communities or sub-castes or synonyms in the Central List of OBCs and classifying them into their respective sub-categories.
- Part XVI deals with reservation of SC and ST in Central and State legislatures.
- Article 15(4) and 16(4) of the Constitution enabled the State and Central Governments to reserve seats in government services for the members of the SC and ST.

Neha Sharma answered |
The time period of a pendulum is given by the formula 
Where 'T' is the time period, 'l' is the length of the pendulum, 'g' is the acceleration due to gravity.
Since the lift is moving with a constant velocity downwards, there will be no change in the acceleration of the pendulum. Hence time period will remain same.

Putting x = sinA, y = sinB, we get
cos A + cosB = a(sinA − sinB)
⇒ A − B = 2cot−1a

On differentiating w.r.t. x, we get
Clearly, it is a differential equation of the first order and first degree.

Introduction:
Frenkel and Schottky defects are common types of point defects that occur in crystalline solids. In Frenkel defect, an ion is displaced from its lattice site into an interstitial site, while in Schottky defect, an equal number of cations and anions are missing from their respective lattice sites. Let's analyze each compound to determine which one is likely to show both Fr... more
