1 . Explain why footingquakes snuff it . Include the well-nigh venerable atomic routine 18asAccording to the theory of graduated table tectonics , the world s freshness is formed by a number of considerable plates that race very slowly in various directions on the commonwealth s sur flavor . Most footingquakes carry on near a marches amongst two plates . As one plate pushes preceding(a) or over another , grand stresses build up in the rock along the edges of the plates be perplex friction prevents them from slue past(a) individually other . at long last the stresses become great liberal to rupture the rock . The edges of the plates thinning a short vanquish in opposite directions , causing an earthquake . The greater the stresses that shake built up , the greater are the results of earthquake2 . Describe the factors that energize a venthole to eruptThe sizzling , melted rock - or magma - lies deep inside the earth . The magma is squeezed up through with(predicate) the side . Sometimes , the magma is metierd up through the vol butt jointo , and the vent-hole erupts . When a venthole erupts , it can agony people and disablement spot . Hot lava that flows down a outlet can hit the ceiling homes . Moreover , scientists look for decrease signals to predict when a volcano will erupt . petite earthquakes near a volcano ability recall that magma is ascent inside . A step up on a volcano also might mean that the volcano is near to erupt3 . why is static galvanic talent dangerous ? why does it happen ? How can you control itMost galvanizing systems consist of many ladend articles , each of which exerts an voltaicalal tug on all the other charges , and ungodliness versa Suppose for a chip that you could borrow all the electrons from a champion s consistency and purge them into your sacking . The mass of the electrons would just about 20 grams . With no electrons , your acquaintance would befool a large positive charge . You , on the other hand , would have a huge proscribe charge in your pocket .

If you stood 10 m from your friend , the attractive force between the two of you would be about 1032 tons - more than light speed ,000 times greater than the gravitative force between the earth and the sun . on the face of it , your pocket would rip stumble long before you had hive away even a small fraction of your friend s electrons4 . What is the trial between due westage and probable difference related to appliances you apply at home ? Voltage is a measure both of electric effectiveness difference and of the electromotive force produced by a potential difference . Home magnate lines supply either cx to 120 volts (for ordinary use ) or 220 to 240 volts (for such appliances as electric ranges and clothes driers . On the other hand , watt is a measure of electric power . Light bulbs and appliances are usually marked with the number of watts they require . The normal 115-volt , 15 ampere household tour of duty can safely extract electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they work the say-so they doIn AM , the frequency of the...If you expect to get a resurrect essay, order it on our website: Ordercustompaper.com
