Answer:
The film thickness is 4.32 * 10^-6 m
Explanation:
Here in this question, we are interested in calculating the thickness of the film.
Mathematically;
The number of fringes shifted when we insert a film of refractive index n and thickness L in the Michelson Interferometer is given as;
ΔN = (2L/λ) (n-1)
where λ is the wavelength of the light used
Let’s make L the subject of the formula
(λ * ΔN)/2(n-1) = L
From the question ΔN = 8 , λ = 540 nm, n = 1.5
Plugging these values, we have
L = ((540 * 10^-9 * 8)/2(1.5-1) = (4320 * 10^-9)/1 = 4.32 * 10^-6 m
Answer: 154.08 m/s
Explanation:
Average acceleration
is the variation of velocity
over a specified period of time
:

Where:

being
the initial velocity and
the final velocity

Then:

Since
:

Finding
:


Finally:

Ok so it is 42.8 because if you - 43.9 by 1.1 by the way don’t listen to any of the I just want point
<span>The answer for this statement would be true. A person should accept the reality. Never do something that can possibly hurt you in the future. Do not try to do the impossible because at another period, you can may still be able to change the situation. </span>
