Work = Force x Distance, so you can pull a wagon 10m with 5N of force. Hope this helps :)
Since Fg=(Gm1m2)/r^2, if the masses are halted the gravitational force will be effected as well. In this case, the gravitational force would be lessened as well.
Answer:
(a) 47.08°
(b) 47.50°
Explanation:
Angle of incidence = 78.9°
<u>For blue light :
</u>
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₂ is the refractive index for blue light which is 1.340
n₁ is the refractive index of air which is 1
So,
Angle of refraction for blue light = sin⁻¹ 0.7323 = 47.08°.
<u>For red light :
</u>
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₂ is the refractive index for red light which is 1.331
n₁ is the refractive index of air which is 1
So,
Angle of refraction for red light = sin⁻¹ 0.7373 = 47.50°.
<h2>Unit of Work is Joule.</h2>

Answer:
The thickness of the film is
Explanation:
The relation between the refraction index, and a wavelength is given by
<em>where is the number of fringes, is the wavelength of the incident light, and is the thickness of the film</em>.
<u>From this relation</u>, we have that
wich gives us that
is the thickness of the film.
