Answer:
The distance is 
Explanation:
From the question we are told that
The order of maximum diffraction is m = 2
The wavelength is 
The angle is 
Generally the condition for constructive interference for diffraction grating is mathematically represented as
where d is the distance between the lines on a diffraction grating
So
substituting values
Answer:
W = 0.012 J
Explanation:
For this exercise let's use Hooke's law to find the spring constant
F = K Δx
K = F / Δx
K = 3 / (0.16 - 0.11)
K = 60 N / m
Work is defined by
W = F. x = F x cos θ
in this case the force and the displacement go in the same direction therefore the angle is zero and the cosine is equal to 1
W = ∫ F dx
W = k ∫ x dx
we integrate
W = k x² / 2
W = ½ k x²
let's calculate
W = ½ 60 (0.19 -0.17)²
W = 0.012 J
The answer to your question is -4
Answer:
<em>Wave-Cut Platform</em>
Explanation:
A wave-cut platform, or shore platform <em>is the thin flat area frequently found at the bottom of a shore cliff or along a river, bay, or sea produced by erosion.</em>
When they become apparent as huge areas of flat rock, wave-cut platforms are often most noticeable at low tide.
Very interesting question. I would be happy to answer if it was actually, indeed, a question
