Answer 1

Answer:

This relationship between the angles of incidence and refraction and the indices of refraction of the two media is known as Snell's Law.It was my longtime desire to have a pet in my house. 1 liked to have pets because I can spend time with them and play with them. When I expressed my desire to my parents, they agreed to get me a pet of my choice. I decided to have a parrot as my pet. We went to a pet shop and got a parrot.

Parrots have always been fascinating to me. I liked the colour and the sounds they make. I have heard in books that parrots can be trained to speak. That got into my head as I. bought the parrot.

Every day it was a pleasant feeling in the morning when I went near the cage and saw what my parrot was doing. I gave it the name “Bittoo”. I gave him grains and got excited w hen he had them one by one slowly. I developed an attachment with the bird. I really started enjoying Bittoo’s company.

Banking of roads : To avoid risk of skidding as well as to reduce the wear and tear of the car tyres, the road surface at a bend is tilted inwards, i.e., the outer side of road is raised above its inner side. This is called 'banking of roads'.

Consider a car taking a left turn along a road of radius r banked at an angle θ for a designed optimum speed V.
