Answer:
they play hide and seek with me and im always the seeker U-U
Explanation:
Answer:
d = 1.82 10⁻⁶ m = 1.82 μm
Explanation:
The diffraction phenomenon is explained by a similar equation Young's double slit equation
d sin θ = n λ
Where d is the spacing between the bars, θ is the angled diffraction, n in an integer representing the order of diffraction and λ is the wavelength of light
Let's calculate
d = n λ / sin θ
d = 1 470 10⁻⁹ /sin 15
d = 1.82 10⁻⁶ m = 1.82 μm
We have: Q = m.s.Δt
m = Q / s.Δt
Here, Q = 19.4 J
s = 6.28 J/g C
Δt = 22.9
Substitute their values into the expression:
m = 19.4 / 6.28×22.9
m = 19.4 / 143.81
m = 0.135 g
In short, Your Answer would be Option A
Hope this helps!
