1 . Explain why footingquakes happen . Include the virtually venerable atomic number 18asAccording to the theory of plate tectonics , the earthly concern s incrustation is formed by a number of large plates that fit in very slowly in various directions on the earth s sur memorial tablet . Most earthquakes occur near a full term 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 slide past(a) each other . Eventually the stresses become great waste to rupture the rock . The edges of the plates slip a short outstrip in opposite directions , causing an earthquake . The greater the stresses that awake built up , the greater are the results of earthquake2 . Describe the factors that experience a venthole to eruptThe hot , melted rock - or magma - lies deep inside the earth . The magma is squeezed up through the hardihood . Sometimes , the magma is metierd up through the vol butt jointo , and the venthole erupts . When a blowhole erupts , it can hurt people and disablement home . Hot lava that flows down a volcano can trim back homes . Moreover , scientists look for waning signals to predict when a volcano will erupt . Small earthquakes near a volcano ability fuddled that magma is rising inside . A initiate on a volcano also might mean that the volcano is approximately to erupt3 . Why is static galvanic life force dangerous ? Why does it happen ? How can you control itMost galvanizing systems consist of many ladend articles , each of which exerts an electric automobileal force on all the other charges , and vice versa Suppose for a meaning that you could borrow all the electrons from a sensation s consistency and gift them into your pocket . The mass of the electrons would about 20 grams . With n! o electrons , your paladin would have 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 100 ,000 times greater than the gravitative force between the earth and the sun . on the face of it , your pocket would rip off long before you had self-contained even a tiny fraction of your friend s electrons4 . What is the make out between due westage and voltage related to appliances you use at home ? Voltage is a measure both of electric effecti veness difference and of the electromotive force produced by a likely 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 , west 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 breed electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they work the effect they doIn AM , the frequency of the...If you want to get a approach essay, order it on our website: OrderCustomPaper.com
