Answer: Hello your question is incomplete attached below is the complete question
Ra = 1132 N
Rb = 522.6 N
Pa = 679.7 N
Explanation:
To determine the scalar components Ra
therefore : Ra = 
= 1132 N
To determine the scalar component Rb
therefore : Rb = 
= 522.6 N
To determine the orthogonal projection Pa of R onto
Pa = 750 cos
= 679.7 N
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:
Explanation:
Electric field due to charge at origin
= k Q / r²
k is a constant , Q is charge and r is distance
= 9 x 10⁹ x 5 x 10⁻⁶ / .5²
= 180 x 10³ N /C
In vector form
E₁ = 180 x 10³ j
Electric field due to q₂ charge
= 9 x 10⁹ x 3 x 10⁻⁶ /.5² + .8²
= 30.33 x 10³ N / C
It will have negative slope θ with x axis
Tan θ = .5 / √.5² + .8²
= .5 / .94
θ = 28°
E₂ = 30.33 x 10³ cos 28 i - 30.33 x 10³ sin28j
= 26.78 x 10³ i - 14.24 x 10³ j
Total electric field
E = E₁ + E₂
= 180 x 10³ j +26.78 x 10³ i - 14.24 x 10³ j
= 26.78 x 10³ i + 165.76 X 10³ j
magnitude
= √(26.78² + 165.76² ) x 10³ N /C
= 167.8 x 10³ N / C .
Global warming is what will happen
<span>If the net force acting on an object increases by 50 percent, then
the acceleration of the object will also increase by 50 percent.
This answer is not offered among the list of choices.
