Answers
Answer:
1. Three types of wire used are :
live wire ( Red colour)
neutral wire(Black colour)
earth wire (Green colour)
2. The left and right of a mirror image appear reversed because of how we perceive the mirror image. The phenomenon where your left appears as the right and vice versa in a mirror is referred to as Lateral Inversion.
3. When a beam of light falls on rough, unpolished surfaces such as wood, paper etc. the light reflects in different directions. Such a reflection of light from an uneven surface is called the irregular or diffused reflection.
4. The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region.
5. The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock.
6. Forests provide jobs and incomes.
Forests host 80 % of all terrestrial biodiversity.
Forests give us oxygen.
Trees and forests are natural cooling systems.
Forests protect us from disasters.
Forests purify soil, water and air.
7. Effective housekeeping can help control or eliminate workplace hazards. Housekeeping is not just cleanliness. It includes keeping work areas neat and orderly, maintaining halls and floors free of slip and trip hazards, and removing of waste materials (e.g., paper, cardboard) and other fire hazards from work areas.
