Answer:
Δx = 2.76 x 10⁻³ m = 2.76 mm
Explanation:
The distance between any two consecutive dark or consecutive bright fringes is given by:
Δx = λL/d
where,
Δx = distance between first and second dark fringe = ?
λ = wavelength of light = 546.1 nm = 546.1 x 10⁻⁹ m
L = distance between slits = 1.35 m
d = slit separation = 0.267 mm = 2.67 x 10⁻⁴ m
Therefore,
Δx = (546.1 x 10⁻⁹ m)(1.35 m)/(2.67 x 10⁻⁴ m)
<u>Δx = 2.76 x 10⁻³ m = 2.76 mm</u>

Answer:
3.5x^2 +25x +250-y=0 derivate this eqn you get 7x +25-1 =0 7x =-24 divided the eqn and you get it then inter the value what you get in first eqn
The second condition is an approach to express the second law of thermodynamics as far as entropy. The equation says that the entropy of a detached regular framework will constantly tend to remain the same or increment – as it were, the vitality in the universe is progressively moving towards turmoil.
