Explanation:
1. Graphite is not used in making ornaments because it is soft, britlle and slippery. It cannot be moulded like gold and silver and neither does it posess and lusture which is a desired characteritics in jewellery.
2. The classrooms are designed in such a way that the distance between the walls are less than 17.2 m. Due to this, the reflections of sound from to walls or echos reach our ears before 0.1 s. Because of this, we are not able to distinguish between the original sound and the echo produced in the classroom.
3. Convex mirrors have the ability to cover wider field of view by forming diminished and virtual image of the objects. Thus, the mirrors fitted on the outside of cars are convex so that larger view of the road can be observed by the driver sitting in the car.
