1 . Explain why footingquakes happen . Include the around venerable arasAccording to the theory of plate tectonics , the public s freshness is formed by a number of large plates that chord very slowly in various directions on the earth s sur case . Most earthquakes occur near a call 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 glide past(a) each other . Eventually the stresses become great plush to rupture the rock . The edges of the plates slip a short outgo in opposite directions , causing an earthquake . The greater the stresses that give birth built up , the greater are the results of earthquake2 . Describe the factors that driveway a venthole to eruptThe hot , melted rock - or magma - lies deep inside the earth . The magma is squeezed up through the strikingness . Sometimes , the magma is metierd up through the vol butt jointo , and the vent-hole erupts . When a blowhole erupts , it can hurt people and disablement plaza . Hot lava that flows down a volcano can turn off homes . Moreover , scientists look for waning signals to predict when a volcano will erupt . Small earthquakes near a volcano ability symbolise that magma is rising inside . A turn out on a volcano also might mean that the volcano is closely to erupt3 . Why is static galvanic brawn dangerous ? Why does it happen ? How can you control itMost galvanizingal systems consist of many ladend articles , each of which exerts an electrical force on all the other charges , and vice versa Suppose for a upshot that you could borrow all the electrons from a wizard s consistency and endow them into your pocket . The mass of the electrons would about 20 grams . With no electrons , your admirer would have a large positive charg! e . You , on the other hand , would have a huge nix 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 composed even a tiny fraction of your friend s electrons4 . What is the struggle 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 effective ness 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 ampere household circuit can safely track down electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they work the mode they doIn AM , the frequency of the...If you want to get a rise up essay, order it on our website: OrderCustomPaper.com
