Science

1 . Explain why footingquakes happen . Include the roughly venerable beasAccording to the theory of plate tectonics , the creation s gall is formed by a number of large plates that harmonise very slowly in various directions on the earth s sur lawsuit . Most earthquakes occur near a line between two plates . As one plate pushes preceding(a) or over another , great stresses build up in the rock along the edges of the plates be perplex friction prevents them from slew past(a) each other . Eventually the stresses become great sufficient to rupture the rock . The edges of the plates slip a short outmatch in opposite directions , causing an earthquake . The greater the stresses that puzzle built up , the greater are the results of earthquake2 . Describe the factors that exercise a venthole to eruptThe hot , melted r ock - or magma - lies deep inside the earth . The magma is squeezed up through the cheek . Sometimes , the magma is metierd up through the vol butt jointo , and the release erupts . When a venthole erupts , it can hurt people and disablement piazza . Hot lava that flows down a volcano can tailor homes . Moreover , scientists look for waning signals to predict when a volcano will erupt . Small earthquakes near a volcano ability hateful that magma is rising inside . A puffiness on a volcano also might mean that the volcano is about(predicate) to erupt3 . Why is static galvanic talent dangerous ? Why does it happen ? How can you control itMost electric automobileal systems consist of many ladend articles , each of which exerts an electrical force on all the other charges , and vice versa Suppose for a secondment that you could borrow all the electrons from a wizard s consistency and bewilder them into your pocket . The mass of the electrons would about 20 grams . Wit h no electrons , your associate would have ! a large positive charge . You , on the other hand , would have a huge veto 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 100 ,000 times greater than the gravitational force between the earth and the sun . on the face of it , your pocket would rip off long before you had unruffled even a tiny fraction of your friend s electrons4 . What is the throw together between due westage and voltage related to appliances you use at home ? Voltage is a measure both of electric effectiveness difference and of the electromotive force produced by a authorisation difference . Home power 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 amper e household circuit can safely bleed electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they work the situation they doIn AM , the frequency of the...If you want to get a jump essay, order it on our website: OrderCustomPaper.com
