Resistance</h3>
Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:

Given that R₂ = 469 ohm, hence:

But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
![R_1=\rho \frac{l_1}{A_1}=\rho *\frac{6l_2}{[\pi (1/5)r_2]^2} =150 * \rho \frac{l_2}{[\pi r_2]^2}=30*469=70350\ ohm](https://tex.z-dn.net/?f=R_1%3D%5Crho%20%5Cfrac%7Bl_1%7D%7BA_1%7D%3D%5Crho%20%2A%5Cfrac%7B6l_2%7D%7B%5B%5Cpi%20%281%2F5%29r_2%5D%5E2%7D%20%3D150%20%2A%20%5Crho%20%5Cfrac%7Bl_2%7D%7B%5B%5Cpi%20r_2%5D%5E2%7D%3D30%2A469%3D70350%5C%20ohm)

Homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. While, heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
Example of heterogeneous :
Oil and water
Smog
Example of homogeneous:
Salt water
Air
Both, there are two different types of molecules to distinguish that
Answer:
26.6°
Explanation:
refractive index of diamond, n = 2.23
When a ray of light passes from denser medium to the rarer medium and refracts at an angle of 90 degree from the normal of the surface, such angle of incidence in the denser medium is called the critical angle.
By the Snell's law

For critical angle, angle of incidence is critical angle, i = θc and angle of refraction, r = 90
So,
Sin θc / Sin 90 = 1 / 2.23
Sin θc = 0.448
θc = 26.6°
Thus, the critical angle is 26.6°.
