Sol. Kapurthala is a city in Punjab state and famous for production of railway coaches, it was established in 1986 by the government of India.








S7. Ans.(a)
Sol. Two layers of a cloth are warmer because air trapped between the layers acts as thermal insulator restricting the heat transfer. 

S8. Ans.(c)
Sol. A mobile phone charger is basically a step-down transformer which converts high voltage to low voltage. 

S9. Ans.(a)
Sol. Image formed by a plane and a convex mirror is always erect. Concave mirror forms image both erect and inverted depends on the position of the object from the mirror. 

S10. Ans.(a)
Sol. From the ray diagram, it is very clear that the image of the object placed at infinity from a concave lens is virtual diminished and at the focus of the lens.
