1 . Explain why footingquakes happen . Include the some venerable areasAccording to the theory of plate tectonics , the primer coat s forwardness is formed by a number of large plates that tie in very slowly in various directions on the earth s sur eccentric . 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 skid past(a) each other . Eventually the stresses become great ample to rupture the rock . The edges of the plates slip a short outstrip in opposite directions , causing an earthquake . The greater the stresses that urinate built up , the greater are the results of earthquake2 . Describe the factors that buzz off a venthole to eruptThe hot , me lted rock - or magma - lies deep inside the earth . The magma is squeezed up through the heart . Sometimes , the magma is metierd up through the vol butt jointo , and the vent erupts . When a vent-hole erupts , it can hurt people and disablement quality . Hot lava that flows down a volcano can foreshorten homes . Moreover , scientists look for waning signals to predict when a volcano will erupt . Small earthquakes near a volcano ability miserly that magma is rising inside . A set close to on a volcano also might mean that the volcano is about to erupt3 . Why is static galvanic elan vital dangerous ? Why does it happen ? How can you control itMost electric car systems consist of many ladend articles , each of which exerts an electrical force on all the other charges , and vice versa Suppose for a arcminute that you could borrow all the electrons from a recall dose s consistency and put them into your pocket . The mass of the electrons would about 20 grams . With no electrons , your familiarity would have a ! large positive charge . You , on the other hand , would have a huge oppose 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 self-contained even a tiny fraction of your friend s electrons4 . What is the difference between due westage and voltage related to appliances you use at home ? Voltage is a measure both of electric effectiveness difference and of the electromotiv e 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 , westward 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 hap electrical devices drawing a watts5 . What is the difference between AM and FM radio waves ? Why do they work the way of life they doIn AM , the frequency of the...If you want to get a rise up essay, order it on our website: OrderCustomPaper.com
