Refraction is the change in direction of a wave, caused by the change in the wave's speed. Examples of waves include sound waves and light waves. Refraction is seen most often when a wave passes from one transparent medium to another transparent medium. Different types of medium include air and water. When a wave passes from one transparent medium to another transparent medium, the wave will change its speed and its direction. For example, when a light wave travels through air and then passes into water, the wave will slow and change direction.
Explanation:
Below is an attachment containing the solution.
Answer:
can be called kinetic or potential energy
Explanation:
To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.
The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,
Equating both equation we have that,
Rearranging to find the angle we have that,
Our values are given as,
Therefore the minimum angle will be 11.53°
