<h2>
Cohesion </h2>
Is the attraction that molecules have for others of their same type.
<h2>
Adhesion </h2>
Is the attraction that molecules have for others of different type by intermolecular forces.
A good example of both is water that can stick to itself through hydrogen bonds (cohesion) and can also stick to a glass due to adhesion.
So, while Cohesion is the force of attraction between adjacent particles within the same body, Adhesion is the interaction between the surfaces of different bodies.
Explanation:
For air, n1 = 1.00003; for water, n2 = 1.3330
Given: θ2 = 30 degrees, then
θ1 = arcsin [(n2/n1) sin θ2]
= arcsin [(1.3330/1.0003) sin (40)]
= 58.93 degrees
Note that since, in this example, light is traveling from a medium of higher density (water; n2 = 1.3330) to a medium of lower density (air; n1 = 1.0003), then n2 > n1, and the angle of refraction (θ1) is larger than the angle of incidence (θ2), thus the light bends away from the normal (in this example, the vertical) as it leaves the water and enters the air.
I think the answer to this is centripetal force.
I may not be correct.
Answer:
The constant angular acceleration of the wheel is 12.16 rad/s²
Explanation:
Given;
initial angular distance, θ = 28
time of the motion, t = 5 s
initial angular velocity is calculated as;
final angular velocity is given as, 
The constant angular acceleration is calculated as;
Therefore, the constant angular acceleration of the wheel is 12.16 rad/s²
