Answer 1

Answer:

1. 1. An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. ... Scientists can't tell that an earthquakeis a foreshock until the larger earthquakehappens. The largest, main earthquakeis called the mainshock.

2. Covering bare bulbs with louvres, lenses or other devices to control light. Increasing the brightness of the area around the glare source. Using adjustable local lighting with brightness controls. Positioning light fixtures to reduce reflected light that is directed toward the eyes.

1. 3. Lightning conductor is a metal rod placed on a building and connected with the ground below to protect the building from being damaged bylightning. Its purpose is to offer a low resistance path to lightening and allow it to .

Answer 2

Answer:

Ans =1) An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismicity, or seismic activity, of an area is the frequency, type, and size of earthquakes experienced over a period of time. The word tremor is also used for non-earthquake seismic rumbling.

Ans =2) Appropriate lighting, without glare or shadows, can reduce eye fatigue and headaches. It highlights moving machinery and other safety hazards. It also reduces the chance of accidents and injuries from ‘momentary blindness’ while the eyes adjust to brighter or darker surroundings.

Ans =3)a metal rod or wire fixed to an exposed part of a building or other tall structure to divert lightning harmlessly into the ground.

a person or thing that attracts criticism, especially in order to divert attention from more serious issues or allow a more important public figure to appear blameless.
