The horizontal component is calculated as:
Vhorizontal = V · cos(angle)
In your case Vhoriontal = 16 · cos(40) = 12.3 m/s
Answer: 12.3 m/s
Answer:
2n t = m λ₀
, R = 0.240 mm
Explanation:
The interference by regency in thin films uses two rays mainly the one reflected on the surface and the one reflected on the inside of the film.
The ray that is reflected in the upper part of the film has a phase change of 180º since the ray stops from a medium with a low refractive index to one with a higher regrading index,
-This phase change is the introduction of a λ/2 change
-The ray passing through the film has a change in wavelength due to the refractive index of the medium
λ₀ = λ / n
Therefore Taking into account this fact the destructive interference expression introduces an integer phase change, then the extra distance 2t is
2 t = (m’+ ½ + ½) λ₀ / n
2t = (m’+1) λ₀ / n
m = m’+ 1
2n t = m λ₀
With m = 0, 1, 2, ...
Where t is the thickness of the film, n the refractive index of the medium, λ the wavelength
The thickness of a hair is the thickness of the film t
2R = t
R = t / 2
R = 0480/2
R = 0.240 mm
Answer:
d). The value of y should be -32m
Vx=0.92 m/s
Explanation:
Using equation of motion uniform to y motion
So to find t that is the same time for all the motion
The value of Xf=-3.2m because the g is negative from the axis
Now in the axis 'x' to find Vx
